00:00:2910, 13, 14, 16, 19, 23, 24, 27, 29, 32.

00:00:46जब आप ये कर लें, इसके वाद आपको करना है concert builder 1 and 2, उसके वाद आपको करना है concert builder 4, उसमें कुछ एक selected सवाल है, 3, 4, 5, 7, 8 और 10.

00:01:01आप जब सवाल कर रहे हों, तो हो सकता है कि एक दो सवाल mix up मिल जाए, तो उन्हें छोड़ दीजे, mostly जो सवाल है वो उन्हीं topic के अभी तक हमने लिए, जो आपने पढ़ लिए हैं, जब ये सारा कुछ आप कर लें, तो आपके इस वाले, नए वाले module में, हर chapter में कुछ salt example भी

00:01:31perception ये होता है कि भई, वैसा करके मतलब easy है, लेकिन यहाँ पर जो concept builder है, उसमें अच्छे सवाल है, तो आप observe करिएगा, जब भी मैं कभी concept builder की homework दूँगा, तो या तो सबसे last में दूँगा, और या तो कई बार बहुत ही high level है, किसी chapter में तो नहीं भी करते हैं, लेकिन जब �

00:02:01page number 256 में, page number 256, 123, ये homework रहेगा आपका next class, and again, जब आप ये homework कर रहे हैं, तो सबसे जरूरी, जो भी आपका पुराना homework है, पहले उसे complete करें, तो पुराना homework complete करें, जब ये सारा का सारा हो जाए, फिर से आपको revise करना है, from lecture 1 to lecture last, sir, paper का syllabus कितना हैगा, पिछरी class में बताया था,

00:02:31purpose एक बड़ा simple है, कि आप हर lecture को important माने, आप हर lecture को properly पढ़ाई करें, कई बार हम paper के त्यारी में, paper के पहले वाला lecture या कुछ lecture मिस करते हैं, और एक सवाल पुरी chapter से कई बार बनता है, और उसी chapter से बनता है, जिसे आप, उस lecture से बनता है, जिसे आप छोड़ देते हैं, इसलि�

00:03:01salt hydrolysis के सवाल कर रहे थे, उन्हीं सवालों में, एक सवाल मैंने आपको homework दिया था, इस्टार्ट हो रहा हूँ, बच्चों, आपका ध्यान चाहिए, उन्हीं सवालों में मैंने आपको homework दिया था, 10K power minus 2 molar, HCO whole twice barium, और सायद मैंने यहाँ पे PKB दिया था, और PKB format iron का, सायद

00:03:31चारिए, अगर आप solution को पहचानेंगे, तो यह जो solution है, ना acid का है, ना base का किसका है, salt का, देखो प्यारे बच्चों, यह तो समझ में आ गया, यह solution salt का है, अब अगला सवाल यह है, कि किस type के salt का है, क्योंकि हर salt का अपना एक अलग formula है, अपना एक अलग concept है, तो सबसे पहल

00:04:01acid और strong base का salt है, हाया ना, अब क्योंकि यह weak acid और strong base का salt है, तो formula हमें वही वाले लगाने है, कहीं कोई दिक्कत नहीं है, अपना formula लगाते हैं, तो pH का formula जो कि 7 से ज़्यादा होगा, तो 7 प्लस half, Pka प्लस half log C, बोलो हाया ना, आप सब ने इसे value रखा होगा, sol क्या होगा, क्य

00:04:31इस पूरी कहानी में, बस, बस ठीक है, ठीक है बेटा, इस पूरी कहानी में, इस पूरी कहानी में, जो interesting point था, वो यह नहीं था, क्या answer क्या है, सवाल अगर आप समझ गए, तो तुरंत आ जाएगा answer, खेल यह था, क्या आखिर हमें करना क्या है, आप जब ध्यान से देखें

00:05:01क्या आज weak parents से format iron आया है, यानि आज पानी को कौन तोड़ेगा, format iron, तो इस पूरे formula में हमें concentration, पूरे salt का लिखना है, कि format iron का, format iron का, अब हमारा पूरा का पूरा focus हो चुका है, format iron के concentration में, तो प्यारे बच्चों, जैसा कि आप देख पा रहे हैं, HCO whole twice barium का, जब dissociation होगा,

00:05:31यानि कि आज इस सवाल में कितना है, 10 की पावर, minus 2, तो मैं कहूंगा, what should be the concentration, 2 into 10 की पावर, minus 2, बलो हाया न, यह जो ionic equilibrium है, एक सांप सीड़ी के जैसा है, जहां हर step में सांप दसने को बैठे, सांप सीड़ी में कई बार 99 तक पहुँच जाते थे, और फिर कई बार वो सां

00:06:01होसे बड़ा hurdle है, और वो है calculation का, अब हम कैसे calculation करते हैं, सुनिएगा, जब हम आगे बढ़ते हैं, तो pH is equal to 7 plus half PK, लेकिन प्रस्ट में हमें PK नहीं दिया, क्या दिया है, PK भी, अब हमारा अगला target क्या निकालनेगा है, PK, तो PK कैसे निकाले, जैसा मैंने आप से कहा था, क्या

00:06:31अब यहाँ पे values को रखते हैं, तो 7 plus half into 10 plus half into log C, और C की value है 2 into 10 की power minus 2, बोलो हाँ या ना, अब यहाँ पे सबसे बड़ा hurdle किसका है, calculation का, आप यखीन नहीं करेंगे, यही calculation हर बच्चा करता है, और मुस्ली बच्चों के answer अलग आते हैं, आज फिर भी आप पढ़ रहे हैं,

00:07:01मत करो जहाँ आपने किया है, उस पन्ने को बदल दो, उस जगे को बदल दो, वहना दिमाग में ऐसा pressure होता है, कि अगर आपने 2 को 4 लिखाता है, तो 4 नजर ही नहीं आता, 2 ही नजर आता है, इसलिए अगर कभी calculation mistake हो जाए, तो वहाँ दुबारा calculation मत करिये, जहाँ आप कर र

00:07:31log C में गलती होती है, तो समभल के करो न या, क्यों मैं इसे हवा में करने कोशिस करूँगा, यह दिमाग में trigger हो जाना चाहिए, यहाँ लिखा half चलेगा, log A into B, log A into, तो मैं कह दूँ log A plus log B, बोलो done, अब क्या 10 की power minus 2 से बाहर minus 2 आएगा, log 2 की value 0 point, तो minus 2, 0 point 3, minus 1 point, upon 2, तो �

00:08:01minus 1 point 7, by 2, और यह आएगा, 170 बटे दो, यानि 0 point 85, और minus करोगे तो answer जाएगा, 11 point, बोलो हाई अला, मैं नहीं कहता हूँ, calculation करने का यह मात्रिक तरीका है, कुछ बच्चे क्या करते हैं, यहाँ पे minus लगाते हैं, और यहाँ भी minus लगाते हैं, तो जब यहाँ minus लगा दिया, �

00:08:31बोलो हाई ना, और आपके सामने answer है, and answer is 11.15, इसी concert पे, इसी concentration पे उन्होंने buffer में खेला है, उन्होंने J23 में भी है, आपके module में solve example भी है, बस इतना था, कि अगर आपने concentration 10 की power minus 2 रख दिया, तो option कोई और match करेगा, और सही concentration रखा तो option कोई, बोलो हाई ना, अगर आप सम�

00:09:01concentration नहीं है, यह उस आयन की concentration है, जो पानी को तोड़ रहा है, बैसे कितने बच्चों ने solve कर लिया था, यही answer आया था, ठीक है, तो इस पूरी कहानी में एक छोटा सा concept था, C is not the concentration of iron, C is the concentration of that iron, which undergoes hydrolysis, बढ़ूं आगे, इसी profile का, similar profile का एक सवाल और देता हूं, और सवाल है,

00:09:31लिखिएगा अगला सवाल, if, if pka, if pka of lactic acid, if pka of lactic acid is 5, if pka of lactic acid is 5, उन्होंने हमें lactic acid का pk दे रखा है, और नीचे lactic acid का formula लिखा था, ठीक है,

00:10:01lactic acid जो कि अपने आप में एक organic acid है, बताइए इससे हम weak माने के strong माने, दूसरा concept, क्या हमें lactic acid का pk दे रखा है, अगर pk दिया है, तो सौभाविक सिवात हमें weak ही मानना पड़ेगा, क्योंकि इस पूरे chapter में strong का कभी भी equilibrium constant सवाल न देता है, न पूचता है, चलेगा, अग

00:10:31देन calculate the pH of 0.005 molar, देन calculate the pH of 0.005 molar, calcium lactate solution, calcium lactate solution, calcium lactate solution,

00:10:55अब इस पूरी कहानी में, आपने calcium lactate का नाम पहरी बाल सुना है, लेकिन आपको दिमाग में इतना concept लगाना पड़ेगा, कि lactic acid से एक ही hydrogen निकल सकता है, यानि कहने को तो बहुत tough सा लग रहा है, लेकिन behavior वैसा ही है, जैसा formic, अर बोलो भाई, अगर मैंने आपके सामने य

00:11:25बस फरक कितना है, आज formic acid नहीं, आज कौन सा acid है, तो ठीक है साब, lactic acid है, तो lactate बना है, लेकिन अगर उसमें replaceable hydrogen एक है, तो जैसे वहाँ बनाता वैसे वहाँ भी, बोलो हाया ना, concept लगाईए, आपके answer के weight में, answer बोलना नहीं है, बन जाये तो हाथ खड़े करेंगे, answer ब

00:11:55concentration लिखना सीख जाए, वो लिखना सीख गया है, तो सवाल आपके गलत हो ही नहीं सकते हैं, examiner कितना भी कोशिस करें,

00:12:01calculation error नहीं आ सकता, बिल्कुल perfect answer आता है, क्योंकि values ऐसी हैं कि calculation error आ ही नहीं सकता है,

00:12:19चलिए, जो बच्चे अभी भी नहीं समझ पाए, उनको आसान बनानी के लिए मैं कह दूँ, calcium lactate का formula हो जाएगा, calcium la hole twice, मान लो,

00:12:28अरे मान लो, कुछ दिर पहले सर ने HCO hole twice barium वाला सवाल करके बताया था, अरे यहां lactate लिखा है, मान लो ना यार,

00:12:37खत्म है सवाल, वो लो बन जाएगा, पूरी क्लास cancer चाहिए, पूरी क्लास, सवाल एक आदत के जैसे है, जब तक सवाल नहीं लगाएंगे, तब तक chapter grip में नहीं आएगा,

00:12:49जितने सवाल दिये गए, अगर एक बच चाहिए, जब से रोज homework करे ना, end of the day, आप जब module के पन्ने पलटेंगे, एक-एक सवाल में टिक लगा होगा,

00:12:57चाहे बक size का हो, चाहे concept builder का, चाहे LP गा, यही तो ताकत है हमारी यार, रोज 10-10 सवाल लगाते रहो, कितना बड़ा पहाड पूरा हो जाएगा, पता ही नहीं चलेगा, बस रोज कुछ न कुछ करते रहे हैं, बढ़ू आगे, चलिए साब, कितना बच्चों का answer आ चुक है,

00:13:27पीएच निकालना है, तो क्या पीएच इसका साथ से ज़्यादा साथ से काम, क्यों calcium strong base होता है कि weak base, कुछ न बोला, कुछ strong ही माना, और कुछ, अगर के भी बोला जाएगा, तो weak माना जाएगा, बात हो गई है, मेरे प्यारे बच्चों, क्या यहां से concentration आ गया, क्या आपको

00:13:57क्या हम पीएच लिख ले, और जब आप यहां से पीएच का formula लिखते हैं, तो 7 plus half pka plus half log c, जिस बच्चे से calculation नहीं आता है, उसका फर्ज बनता है, वो बोर्ड में देखे, half into 5 plus half into log c, और यहां लिखूगा मैं log, 10k power minus 2, जैसे log c आएगा, समल के solve करना है, यही सर हमेशा कहत

00:14:27अब यह कितना आएगा, 7 plus 2.5, बोलो डण, क्या यहां से minus 2 बाहर आएगा, minus 2 by 2, minus log 10 की value, यहां minus 1 कह दूँ चलेगा, और इसको solve करोगे answer कितना आएगा, 8.5, is this clear or not, बढ़ू आगे, प्यारे बच्चों आओ देखते हैं, हमने अभी तर क्या-क्या सीक लिया है, अब यहा

00:14:57से कुछ दिरों पहले एक chapter शुरू हुआ, जिसका नाम था अरेनिया, सहब काहनी equilibrium बोलो हाया ना, मैंने कहा, इस chapter हमें एक ही काम करना है, बोले तो, क्या हमने single solution का pH निकालना सीखा, single strong acid, single strong base, single weak acid, single weak base, हमने सब का pH निकाला कि नहीं निकाला, और अगर कभी strong आए, तो concept, ज

00:15:27मोनो चाहे हो, पॉली, चाहे हो, चाहे हो, और जब भी weak आएगा, तो सोचा जाएगा, मोनो है कि पॉली, मोनो है तो O, D, L, पॉली है तो एक alpha, एक से जादा alpha, या तो K, आएगा, याद है कि नहीं आदे, पक्का, single single, हो गया, mixing वाला भी, S, A, S, B, S, B, W, W, कितनों को formula या

00:15:57A1, C1, plus K, A2, C2, याद आया, WA, WA, W, W, W, S, A, S, B, अलग-अलग खिलाडी की एक जैसे, अलग-अलग खिलाडी की एक जैसे, ताकत जुडेगी, घटेगी, ताकत भुले तो gram, N1, V1, N2, V2, कभी होगा बराबर, कभी होगा जादा, कभी होगा कभी होगा, कभी होगा acid, क�

00:16:27जब स्ट्रॉंग के साथ वीक आए, को मनाय निफिक लगाया, और स्ट्रॉंग वाला ही H+, माना, क्या S, B, W, B, होगया, क्या S, B, W, A, होगया, हुआ की नहीं हुआ, स्ट्रॉंग-बेस के साथ वीक एसेड मिलाया, जाएगा, तो सॉल्ट बन, और सॉल्ट का पी-एच निक

00:16:57क्या ये मिलाने जुलाने कारिक्रम चल रहा, और सम्मे पानी वाला केस भी, अरे बोलो ना यार, अब क्या हुआ, जरा ध्यान से सुनिएगा, आज आप पुरसत में खाली बैठे थे, मान लो, आज आप पुरसत में खाली बैठे थे, और आपने जो आखरी सलूशन बनाया �

00:17:27ये सॉलूशन एसिड का है, बेस का किस सॉल्ट का, किस टाइप का सॉल्ट है, वीक एसिड, वीक एसिड, वीक एसिड, बोलो भाई, क्या मुझे इसका पी एच निकालना आता है, क्या बच्चे बच्चे को पी एच का फॉर्मला आता है, इसका पी एच का फॉर्मला है, 7 प

00:17:57Don't claim in 0-2-3-12-3-4-0-3-10-3-10,

00:18:08What will be ajsion?

00:18:10should the power of O ?

00:18:11How are you,

00:18:13how are you,

00:18:24if the power of O a value-tooth equip you need ałącoule function,

00:18:29it will resolve the power of O ?

00:18:31If the power of O is chosen,

00:18:36लेके गए वो instrument लेके गए जिससे pH न पा जाता है आपने जब उससे pH निकाला pH x से हलका सा कम आया कितना कम कितना कम अगर इसकी value थी 5 मान लो वैसे इसकी value 6.5 है मान लो तो अगर 6.5 माना तो इसका जो pH आएगा वा आया 6.42 6.42 यानी अंतर कितना आया ना के बराबर अरे बोल

00:19:06but then you get a little bit of a nice

00:19:10of you.

00:19:121 minute.

00:19:14You can see strong?

00:19:15No.

00:19:16Why is strong?

00:19:17That is the strong base of OH minus sign?

00:19:18You can see OH minus concentration.

00:19:20You can see OH minus concentration.

00:19:21So you want pH.

00:19:22You want to add pH?

00:19:23No.

00:19:24No.

00:19:25No.

00:19:26You want to add to pH?

00:19:27No.

00:19:28Do you want to add pH?

00:19:29No.

00:19:30No.

00:19:31You want to add pH.

00:19:32No.

00:19:33No.

00:19:34foreign

00:19:48foreign

00:20:02You have also asked about dilution.

00:20:0510% dilution, 1% dilution, 100% dilution, 2% dilution.

00:20:10You have to find a pH of water.

00:20:16How much water?

00:20:19How much water?

00:20:21How much water?

00:20:23This water.

00:20:25How much water?

00:20:33How much water?

00:20:35Oh, cruciate.

00:20:39yeah, help me...

00:20:43How much water?

00:20:45What

00:20:46water?

00:20:51Copy me, Next Reading, Buffer, Solution.

00:20:55Copy me, Next Reading, Buffer, Solution.

00:20:59Buffer, Solution.

00:21:03Copy me, Next Reading, Buffer, Solution.

00:21:07I will read it.

00:21:09Buffer, Solution.

00:21:11Now, here you will have an idea that the end of the buffer solution is what is going on.

00:21:16In the Russian language, I say that the buffer solution is what is going on.

00:21:19It is a solution.

00:21:49It is a solution whose pH almost remains constant.

00:22:02Whose pH almost remains constant.

00:22:10Sir, you haven't said it constant.

00:22:12Almost remains constant.

00:22:14On addition of small amount of SA or SB or on dilution.

00:22:32On addition of small amount of SA or SB or on dilution.

00:22:40Bucs, you can say it because of the change, it is actually constant.

00:22:53Then, it is a solution.

00:22:56So total, what kind of methods were there?

00:22:58A little bit, a little bit.

00:23:02But in pH, there was no change.

00:23:04What was the name of the world? Buffer.

00:23:08Now, this name is Buffer.

00:23:10Buffer means Registence.

00:23:12What does that mean?

00:23:14Some years ago, it used to be 2G.

00:23:16If it used to be a video,

00:23:18it used to be a circle,

00:23:20and it used to be a buffer.

00:23:22It used to be a buffer.

00:23:24If it used to be a buffer,

00:23:26it seems like hanged.

00:23:28Hanged to be a little change.

00:23:30Right?

00:23:32So Buffer, why do we say?

00:23:34Because if it's X,

00:23:36it's a little bit.

00:23:38It's a little bit.

00:23:40It doesn't change.

00:23:42It doesn't change.

00:23:44It doesn't change.

00:23:46It doesn't change.

00:23:48It doesn't change.

00:23:50It doesn't change.

00:23:52It doesn't change.

00:23:54It doesn't change.

00:23:56It doesn't change.

00:23:58It doesn't change.

00:24:00Next point.

00:24:02Buffer means.

00:24:04Buffer means.

00:24:06Resistance.

00:24:08Buffer means.

00:24:10Resistance to change.

00:24:12Resistance to change its pH.

00:24:14To change its pH.

00:24:16Buffer means.

00:24:18Resistance to change its pH.

00:24:20To change its pH.

00:24:22To change its pH.

00:24:24To change its pH.

00:24:26This Code here is the same way.

00:24:28It doesn't change its pH.

00:24:30To change its pH,

00:24:32if it doesn't change its pH.

00:24:34Whether it's such a buffer solution

00:24:36has the same way.

00:24:37It is then the same way.

00:24:38You have to change that.

00:24:40Why any solution becomes buffer?

00:24:53Why any solution becomes buffer?

00:24:59Why any solution becomes buffer?

00:25:05Why any solution becomes buffer?

00:25:35If you have to be buffer, you will not say it.

00:25:40You will not say it.

00:25:41But you will remain.

00:25:43Where is buffer?

00:25:44Where is buffer?

00:25:45Insonity will go more multiple.

00:25:47In the same way, if the buffer is more than buffer, then you will go lower.

00:26:01A buffer is what is the pH of the change?

00:26:03Is it the good or not the good of the change?

00:26:05So, the buffer action will be more than the better.

00:26:07So, the buffer will be better.

00:26:09So, the pH will change in the lower part.

00:26:11So, the next point.

00:26:13You can write the next point.

00:26:15Why any solution becomes a buffer?

00:26:17So, because of the buffer action.

00:26:19Because of the buffer action.

00:26:23The buffer action is the only reason

00:26:26that a solution will become a buffer.

00:26:28What is the buffer action that you want to call?

00:26:30If you want to call it in your local language,

00:26:32then say it is a buffer.

00:26:34What is the buffer action?

00:26:38What is the diagram also?

00:26:40Now, we'll listen to it.

00:26:42So, if we're using the salt,

00:26:44we'll understand.

00:26:46So, the salt is the weak acid, weak base.

00:26:48If the salt is weak acid,

00:26:50then we will have the conjugate ions?

00:26:52My dear, what is salt,

00:26:54is the strong electrolyte,

00:26:56is strong electrolyte is the world's salt is strong electrolyte is the exception

00:27:02is no one is not all salts are strong electrolyte without a single exception

00:27:10when salt goes in water and goes in water and goes in water and goes in water and goes in water

00:27:15is the amount of acid acid and ammonia to which acid acid which added it汁 acid

00:27:22it will be extra and strong ambience went by the heat of the worker have

00:27:28a Pop right there is no work and iron of the sun should be are duty and

00:31:12have said that the buffer is a buffer, but in the same way, strong conjugate acid and strong

00:31:18conjugate base is a combination of the buffer. So, the buffer is a new thing. The strong

00:31:23conjugate mixture is what the buffer is. So, the buffer is a solution that if you

00:31:40are a little bit like this or a little bit like this, then the pH is not going to be

00:31:47a specific change. Now, my intention is that the acid is made of acid, so it will not

00:31:50be that much as it will be. But it will be less than that, that the buffer is not going

00:31:55to be as much as it will be. So, the pH is not going to be constant, but it will be almost

00:32:01constant. So, the buffer is not going to be constant. If you are going to be an

00:32:33I can't help my PS. I can't help my PS. The whole ACETA, does it mean?

00:32:37You understand?

00:32:38It means this whole story is not like that you want to get the mind to get this or get this.

00:32:42You will find a limit.

00:32:45Then you will find the limit on the very dark concept.

00:32:47You will find the limit on this very dark concept.

00:32:48Now, in the same case, you will have a limit like human being.

00:32:50So, this is the limit.

00:32:52The limit will be the limit.

00:32:54What do you want to write?

00:32:55I will write the point.

00:32:56The tendency of..

00:33:02tendency of, tendency of buffer solution, tendency of buffer solution to consume, to consume extra added, tendency of buffer solution to consume extra added,

00:33:29H plus or OH minus IN, extra added H plus or OH minus IN and convert into molecules which will not dissociate further.

00:33:59Convert into molecules which will not dissociate further known as buffer action.

00:34:09Known as buffer action.

00:34:12This process, buffer action.

00:34:15Then, buffer solution is basically, buffer solution is basically combination of strong conjugate acid and strong conjugate base.

00:34:30Buffer solution is basically combination of strong conjugate acid and strong conjugate base.

00:34:37Buffer solution is basically combination of strong conjugate acid and strong conjugate base.

00:35:00My dear, what is the solution

00:35:02that you have in front of salt?

00:35:04Do you know how the salt is?

00:35:07Do you know how the salt is?

00:35:08Do you know the salt is weak acid,

00:35:09weak base, salt, pH,

00:35:10formula?

00:35:11Do you know all the kids

00:35:12who are here?

00:35:18Come on, you understand.

00:35:19Come on, you understand.

00:35:21My dear, if I have a little

00:35:22like this, what do you know?

00:35:24So, what do you know?

00:35:24KKB, what do you know?

00:35:25KK का मतलब क्या है?

00:35:31बेटा, KK का मतलब क्या है?

00:35:34Eclibrium constant

00:35:35कितनी चीजों से

00:35:36depend करता है?

00:35:37एक है reaction,

00:35:38एक है temperature.

00:35:40तीसरा हो कोई पहमाना?

00:35:41फिर समय pH का

00:35:42formula लिख रहा हूँ.

00:35:43Rough कर रहा हूँ.

00:35:437 plus half

00:35:48बोलो भाई,

00:35:49अगर मैंने थोड़ा सा

00:35:50S मिला है.

00:35:51क्या मिला है?

00:35:51तो क्या उसका K बदलेगा?

00:35:53क्या KB बदलेगा?

00:35:55क्या 7 बदलेगा?

00:35:56बोलो ना यार.

00:35:58तो pH बदला कि

00:35:59ना के बराबर बदला.

00:36:00अब आपने थोड़ा सा

00:36:01S भी मिला है

00:36:02और भर भर के पानी मिला है.

00:36:03क्या मिला है?

00:38:38तो मैंने बहुत सरल भासा में कहा

00:38:40pH constant होके सवाल आपको confuse करे

00:38:43तो कहना यह buffer

00:38:44acid के मिलाने से

00:38:46base के pH में change नहीं आए

00:38:49यही buffer कहलाएगा

00:38:51बोलो done

00:38:51मैं आपके रोचक चथ्य बताता हूँ

00:38:53एक रोचक जानकारी बताता हूँ

00:38:55बता दू क्या

00:38:55क्या आप सबको पता है हम सबके अंदर

00:38:57blood है

00:38:58क्या आपको पता है हमारा blood एक buffer है

00:39:00तभी तो कितनी भी कचोड़ी के साथ

00:39:02चटने खालो आप खट्टे नहीं होते

00:39:04सोचो अगर आपका blood buffer नहीं होता

00:39:07सोचो

00:39:07अगर आपका blood buffer

00:39:10तो चटनी खाने के बाद आप खट्टे हो जाते

00:39:13और करेला खाने के बाद आप

00:39:14लेकिन ना आप खट्टे होते हैं

00:39:17ना आप कडवे होते हैं

00:39:18क्योंकि हमारा जो blood है वो कैसा है buffer

00:39:20हमारा जो blood है वो कैसा है buffer

00:39:23and what is the best part

00:39:24what is the best part

00:39:25What is the best part?

00:39:26This blood buffer pH is 7.4,

00:39:29which is what you can find.

00:39:31What happens in this buffer action?

00:39:34What happens in this buffer action?

00:39:36What happens in this buffer action?

00:39:38How does this buffer action happen?

00:39:39I feel a few days.

00:39:41But you can keep H2CO3

00:39:43and HCO3 minus bicarbonate ion

00:39:45that is the buffer action in our blood.

00:39:48It's like a human's...

00:39:51and a human's...

00:39:53You can understand?

00:39:54If it's the buffer action,

00:39:56it will be the buffer action.

00:39:57If it's our blood,

00:39:59it will not be the buffer action.

00:40:01Done.

00:40:02Now, I have said that

00:40:03that every buffer can be used by a human's.

00:40:05Humanity can be used by a human's.

00:40:07If you eat a little,

00:40:09you can eat a little,

00:40:10you can eat a little,

00:40:11you can eat a little.

00:40:12You understand?

00:40:13What is the width?

00:40:14What is the range?

00:40:15What is the limit?

00:40:16The book of our blood

00:40:18is the minimum pH of 7.1

00:40:207.1

00:40:22and maximum pH

00:40:237.7

00:40:24If you have 7.1

00:40:26or 7.7

00:40:27or 7.7

00:40:28or 7.7

00:40:29or 7.7

00:40:30or 7.7

00:40:31or 7.7

00:40:32or 7.7.

00:40:33So,

00:40:34blood

00:40:36blood

00:40:37buffer

00:40:38which is how pH

00:40:39which is the,

00:40:407.4

00:40:41and buffer action

00:40:42that is because of

00:40:43H2CO3

00:40:44and SCO3-

00:40:45range is 7.1

00:40:46to 7.7

00:40:47Okay.

00:40:48Is this a general knowledge? Yes, yes. The question was, if you made a buffer, then why do you make a buffer?

00:40:58Okay, the world has such a solution, which has such a solution, which has such a solution.

00:41:04The biggest question is, is that we need to do that?

00:41:08I will tell you, that there are so many tools, which are written by store at a cool temperature.

00:41:16The reason is, if the temperature will change, then the pH will change.

00:41:23The 7 pH on the 7th, it will be the same.

00:41:27What will happen? The same.

00:41:29The same. If the power is the same, it will also be the same.

00:41:32Do you understand?

00:41:33So, if the power is the same, then the pH will change.

00:41:37If the power is the same, then the action will change.

00:41:41Ultimately, the buffer can be done.

00:41:43The buffer can be done by many times.

00:41:45The question is, how do you make a buffer?

00:41:48How do you make a buffer?

00:41:49How do we make a buffer?

00:41:50How do we make a buffer?

00:41:51How do we make a buffer?

00:41:52Now, the number one, the point number one is the buffer solution.

00:41:56It's the problem of clear.

00:41:57Make one solution, which allows a little bit of water to be the same.

00:41:59The buffer should be the exact History limit.

00:42:01The first solution is a lot of water to be the same country.

00:42:02The first solution comes from pH.

00:42:04The first solution is just 20 per hour.

00:42:05How do we make a buffer solution?

00:42:06The first solution gets the same.

00:42:07The first solution becomes a little bit of water.

00:42:08The first solution is basically enough.

00:42:09This is the first effect.

00:42:10It comes from pH and unter the first time.

00:42:11The first reason why I'm going to do the basic concept.

00:42:12पीएच में चेंज उतना कम होगा, these are the basic concept जो भी तक आपके दिमाग में सेट हो जाए, चलेगा, अब जैसा कि आप जानते हैं, जब भी हम किसी topic को पढ़ते हैं, तीन हिस्सों पढ़ते हैं, theoretical, mathematical, numerical, तो इसे भी हम तीन हिस्सों पढ़ेंगे, सबसे पहले theory cover करते हैं, चलेगा

00:42:42नहीं हुई है, हलो, एक बच्चा नीट की त्यारी करने गया, पहले दिन, क्या मेरा selection होगा, क्या मैं जीत पाऊंगा, क्या मैं ये संघर्सों का दौर लड़ पाऊंगा, संदेह से जो सफर सुरू होता है, वो कभी सफल नहीं होता है, क्या बोला मैं समझ पाए, संदेह सं�

00:43:12कर बनाए, उनको हमने 3 कैटेगरी में डिवाइड किया, और overall देखा जाये, तो हम कह सकते हैं 2 कैटेगरी, सबसे पहले type को हमने कहा, साथ में लिखते चलना, theory साथ में, theory rule, theory साथ में लिखेंगे, साथ में, concept पहले समझेंगे बाद में, numerical जितना समय दुतने में करना है, नह

00:43:42I need a strong conjugate acid or a strong conjugate base.

00:43:46If you can understand the concept that the concept is that

00:43:48that the H-plus will eat.

00:43:50Where the H-plus-O-H will eat tendency,

00:43:54they will make all the buffer.

00:43:55How do you make it?

00:43:56How do you make it?

00:43:57So, let's see.

00:43:58Let's see.

00:43:59Let's see.

00:44:00Let's see.

00:44:01Let's see.

00:44:02Let's see.

00:44:03Let's see.

00:44:04Let's see.

00:44:05Let's see.

00:44:06Let's see.

00:44:07Let's see.

00:44:09Let's see.

00:44:11Let's see.

00:44:13Next.

00:44:14So,

00:44:18this is aMG-Mix buffer,

00:44:20which means aMG-Mix buffer.

00:44:22There is also aMG SCEr particulate,

00:44:26which means aMG-Mix buffer.

00:44:28To strengthen the cure,

00:44:31which means a includes a Interpreter likeMG buffer.

00:44:33It means aMG buffer.

00:44:35For example,

00:44:36a mixture can happen.

00:44:38Now Mixed Buffer in two categories. One is Acidic Buffer and one is Basic Buffer.

00:44:45The story before you start before me, I am going to your mind to you.

00:44:49Acidic Buffer means that it is not that it is Acidic.

00:44:52Acidic Buffer means that it is Acidic.

00:44:55Acidic Buffer means that it is Acid.

00:44:58Basic Buffer means that it is Basic.

00:45:01Basic Buffer means that it is Basic.

00:45:04If you think the adheres are

00:45:24Acidic Buffer for more.

00:45:28Acidic Buffer means that it is Acidic.

00:45:30There will be Acidic.

00:45:33How are Acidic?

00:45:34So acidic buffer called base, basic buffer called base.

00:45:38That pH 7% has no need to be.

00:45:40This concept is set.

00:45:42Let's go.

00:45:43Acidic salt, solution can be acidic.

00:45:46Acidic salt is different.

00:45:48Normal salt has no need to be acidic.

00:45:51Do not know.

00:45:52So this is not a rule.

00:45:54It's not a rule that the name is the solution.

00:45:55It's not a problem.

00:45:56Acidic buffer is not a pH 7% will be less than that.

00:45:59Acidic buffer is the one that we will be using acid.

00:46:01So let's write down the line.

00:46:02Which we have made acid.

00:46:04Which we have made acidic buffer.

00:46:08And which we have made base.

00:46:11Basic buffer is the one that we have made basic buffer.

00:46:13How is acid?

00:46:14How is base?

00:46:15How is the concept?

00:46:16But in my mind, this is my set.

00:46:20Acidic buffer is the one that we have made acid.

00:46:24So as I said before, I will cover the theoretical part.

00:46:28I will cover the next few minutes,

00:46:29I will make this one that I will cover the next few minutes.

00:46:31So let's understand that it is simple or that it is acidic.

00:46:34Because this is not a problem.

00:46:35Step number one is the first solution.

00:46:40So first, it is the first solution.

00:46:42Which acid is the basic?

00:46:44Which is the basic?

00:46:45Which is the simple?

00:46:46Say it.

00:46:47Come and play and play.

00:46:48Find who?

00:46:49Play and play.

00:46:50Play and play.

00:46:51Play and play.

00:46:56Simple buffer.

00:46:57Come and play.

00:46:58Simple buffer.

00:46:59Sir, what is this?

00:47:00What is this?

00:47:01This is a solution.

00:47:02Okay, sir.

00:47:03An aqueous solution of.

00:47:04An aqueous solution of.

00:47:05An aqueous solution of.

00:47:06An aqueous solution of.

00:47:07Salt of.

00:47:08Salt of.

00:47:09Salt of.

00:47:10Weak acid.

00:47:11Weak base.

00:47:12Weak base.

00:47:13Weak acid.

00:47:17Weak B Cause.

00:47:23Weak acid.

00:47:25Weak base.

00:47:26Salt.

00:47:27Salt.

00:47:28silicon.

00:47:29buffer. Can you explain what this is? Why is this a strong conjugate anion? It's a strong

00:47:42conjugate. It's a h plus. It's a h plus. It's a consume. It's a minus. It's a consume

00:47:51कर लिया और solution उसका effect नजर नहीं यही कारण है वो buffer के है तो buffer इसलिए है क्योंकि जो भी h-plus मिलाया जो भी o-h मिलाया उसे solution ने

00:48:02गायब कर दिया घर से जो पैसा उसे गायब कर दिया तो कोई फरक ही नजर नहीं आया पता ही नहीं चला आया की नहीं आया अगले महीने फिर वही हो गया आया ना समझ पा रहें क्या तो ऐसा solution क्या बोला मैंने

00:49:16is weak, then you will get two reactions complete and you will get salt. What will be? What will you get? What will you get? Acid. What will you get?

00:49:24Base. But what will you get? Salt. Tell me, this will be buffer or not? Buffer or not? Buffer or not?

00:49:31This will be a simple buffer or mixed buffer. It will be a substance of salt or salt or weak acid or weak base.

00:49:40Either this or this. Equimolar mixture of. Equimolar mixture of. Weak acid and weak base.

00:49:51If it doesn't say salt in the same way, then you will say that in the copy of the question,

00:49:58that you will say that both are equal and if they are equal, then you will say that how is buffer? Simple buffer.

00:50:05If you are a small question, tell me, my dear children, this is a simple buffer or not?

00:50:14Tell me, my dear children, this is a simple buffer or not?

00:50:18Yes. I'm checking. I'm checking. I'm checking. I'm checking.

00:50:22I'm checking.

00:50:23I'm checking.

00:50:24Now this is a simple buffer or facet.

00:50:25Weak acid?

00:50:26Weak acid?

00:50:27Yes.

00:50:28Base?

00:50:29But two weak ones?

00:50:30Yes.

00:50:31Entre-measible.

00:50:32I'm checking.

00:50:33I see.

00:50:34It's not a much, not a major study.

00:50:35It is the source of salt.

00:50:36It will be a small effort or not?

00:50:39It will be a small buffer.

00:50:39Yes.

00:50:40Do you, it will be a small buffer?

00:50:42Yes.

00:50:43Weak acid?

00:50:44No.

00:50:44Yes.

00:50:45I am checking.

00:50:45gone. If someone is weak as a weak base, then the simple buffer is going to go.

00:50:51A, G, C, N is a simple buffer or not? It's easy to read.

00:50:57What is the buffer? What is the buffer? What is the buffer action?

00:51:01The buffer action is less. The buffer action is less.

00:51:05The buffer is less. The pH is less.

00:51:09The buffer is less.

00:51:16Do you feel free or not?

00:51:18If I give myself a K, KB, I can see that the less KB is less.

00:51:23The less KB is less.

00:51:24The less KB is less.

00:51:26The buffer is less.

00:51:28I don't understand.

00:51:29I don't understand.

00:51:31I don't understand.

00:51:33The buffer is less.

00:51:35The buffer is less.

00:51:37The buffer is less.

00:51:38эфф effect is less.

00:51:39Didn't we, my gut?

00:51:40About this buffer action?

00:51:42The buffer action is less.

00:51:44The buffer action is already discussed.

00:51:46When does this buffer action have discussed?

00:51:49Have you discussed it?

00:51:51Did you get some in-pointления discussion?

00:51:52How many CASX?

00:51:54Yes.

00:51:55Potentially.

00:51:56Entry here, I applied.

00:51:57I don't understand.

00:51:59it

00:52:11I am making a piece of paper and I'm going to see this paper and I'm going to touch this

00:52:16by the way.

00:52:20You know, you've got a lot of people who are very interested in this.

00:52:29There was a lot of people who were interested in this.

00:52:33in which people are very famous.

00:52:35One chapter is the one?

00:56:08completely dissociation

00:56:09that it is not!

00:56:10This acid is the salt.

00:56:12All salts are strong electros

00:56:15without a single.

00:56:17Can I see on paper this one?

00:56:21But on paper,

00:56:22here in the solution,

00:56:24it will be on iron.

00:56:25Can I see acetate iron?

00:56:27Can I see H-plus?

00:56:29Can I see H-plus?

00:56:30Can I see H-plus?

00:56:33If H-plus is acetate iron,

00:56:36foreign

00:56:42foreign

00:56:48foreign

00:56:54foreign

00:57:00foreign

00:57:04I have a little of S b. I have a little of S b. I have a little of S b. So, what?

00:57:11What does it mean to H minus? Now tell us.

00:57:13How can I eat?

00:57:15Na plus. Na plus. I say I will be changing your back. You can eat.

00:57:20Who can eat? Acetate iron.

00:57:24This is minus minus minus.

00:57:26This is so much.

00:57:26I can't get minus minus.

00:57:27It's not going to eat.

00:57:30okay one minute, I have OH minus written, really OH minus will be solution will be base

00:57:34solution will be, so what is inside the base will be, here the solution will be

00:57:40this acid reaction will be or will not do it, say it will be, and in the right

00:57:44meaning of SB or WB, and you will know something odd ion is going to happen,

00:57:49I am going to tell you what I didn't want to do, is that OH minus H plus will be

00:57:54is

00:58:22with the effect.

00:58:23It's not easy to let me know ultimately the effect of the H plus OH.

00:58:27But if you can change your pH to change the way?

00:58:30So, this will be the buffer action or not?

00:58:33Then tell you how it is to make it the buffer or not.

00:58:35The buffer is the reason why the pH is less than the pressure.

00:58:37But the buffer is the reason why it is the acid.

00:58:41We don't know if there is an acidic buffer.

00:58:45If there is an acidic buffer,

00:58:47then it's a standard to require it.

00:58:50Just give a good sound.

00:58:52It's a choice.

00:58:54It's a good sound.

00:58:56It's a good sound.

00:58:58It's a good sound.

00:59:00It's a good sound.

00:59:02It's one cup of salt.

00:59:04It's one cup of salt.

00:59:06This cup of salt.

00:59:08What he said?

00:59:10It's a good sound.

00:59:12You say,

00:59:14It's a good sound.

00:59:16I just, how do you say?

00:59:18it is a conjugate it is a conjugate be hona it is a conjugate be hona it is a conjugate be hona

00:59:27sat me for katein be hona it's just a banke rana so tamasa dekhe ga thali bha jai ga

00:59:34lekin kuch karne wala kya me aasa keh do a big acid hona us-ta strong conjugate base

00:59:42do not understand, is it correct? Is it weak acid?

00:59:49Yes, weak acid will be strong, and we will have a strong base, and we will have a ketion,

00:59:56we will have another one from the bottom, sodium, potassium, rubidium, cesium, barium,

01:00:02strong, magnesium, magnesium, iron, iron, silver, silver, why do you understand?

01:00:11Fundamentals, here are the two of us, and we will say that we will eat,

01:00:17we will understand, or if it is possible, we will say that we will put the water in the water,

01:00:21hydrolysis or not, and when hydrolysis was there, the water was dissociated,

01:00:28ultimately, the H plus and OH minus is going to imbalance, what do you do?

01:00:33So the story of the story is that if there is an acidic buffer, it will be a weak acid,

01:00:37if it is a conjugate, it will be a ketion, which will be a strong base,

01:00:43and if everything is in a container, then you will say that the solution is how it is.

01:00:49Compromise will be the next point.

01:00:50So the first thing we will say is that the buffer action.

01:00:57I don't know.

01:01:27That's the case, it's a case.

01:01:28Buffer action of acidic buffer.

01:01:31Buffer action of acidic buffer.

01:01:38What's the case? Acidic buffer?

01:01:41What's the case?

01:01:42What's the case?

01:01:44What's the case?

01:01:45What's the case?

01:01:46What is the case?

01:01:47For an acidic buffer, which are the following reaction represent buffer action?

01:01:51We need to know the reaction.

01:02:06Now, the line we have in front of you.

01:02:08This line is very detailed.

01:02:10In the past 4-5 years, we have a very easy question.

01:02:15But in the past, one or two times, they have a very good question.

01:02:20And in the same concept, we have a little depth.

01:02:23Right?

01:02:24If you have a solution, if you have a weak acid, it's a conjugate.

01:02:31And in the same way, we will say it's a buffer.

01:02:33I will explain it.

01:02:34Let's just read it.

01:02:36The condition is,

01:02:58We can play both.

01:03:00Because if we play both, then the buffer will not maintain.

01:03:03What does buffer mean?

01:03:04H plus can consume, OH can consume.

01:03:07They can play both.

01:03:09Is this clear?

01:03:20Have you read it?

01:03:22Here you will read it.

01:03:23Buffer action of acidic buffer.

01:03:28If you were small, you wouldn't do anything to me.

01:03:36If you were few times, when you came to my dad,

01:03:40you would do anything to me.

01:03:42You would do nothing to me.

01:03:44You would do anything to me.

01:03:46So the thing is,

01:03:49when you're having a new mind,

01:03:51you might not studyias.

01:03:53You wouldn't study them.

01:03:54Don't start expecting you.

01:03:55You are studying yourself.

01:03:57should I have?

01:03:59do you want us to read it?

01:04:00I should have.

01:04:02We have the same text to see you.

01:04:03And now I need your thoughts in detail.

01:04:07I have suggested you,

01:04:09I have you told my example.

01:04:11I have something else.

01:04:12CST COH plus NAOH

01:04:15What a buffer is or not?

01:04:19You understand?

01:04:21You know it.

01:04:22There is a different answer.

01:04:23I have a simple answer and I will tell you

01:04:25SCS-CoH plus CST-CoNa.

01:04:28Bolo is buffer or not?

01:04:30Step back to board your watch.

01:04:33Step back to board your watch.

01:04:33Post on the or the HTML.

01:04:34hcl plus NaCl.

01:04:35Top up there.

01:04:36Or not?

01:04:37And do a lot of thinking.

01:04:40Don't understand the common action was.

01:04:42The odd action was.

01:04:43Condition number one.

01:04:45Vue acid is it.

01:04:46Conjugate is it.

01:04:47Conjugate is it.

01:04:48This is not.

01:04:49So, evotic buffer.

01:04:51In a way,

01:04:51I have one example.

01:04:52Let's give it a goal.

01:04:53Discuss it.

01:04:53Let's do it.

01:04:54Next point for example.

01:04:56So, dear children,

01:04:57if there is a weak acid,

01:05:01and it is a conjugate,

01:05:03then we will say that it is an acidic buffer.

01:05:09If there is a point,

01:05:10all the points are in star.

01:05:12If there is a point cover,

01:05:13then I have a question.

01:05:15If there is a acidic buffer,

01:05:17then it needs a weak acid.

01:05:19It needs a conjugate,

01:05:21and a cation,

01:05:23which we will say,

01:05:25which is the same effect of your skin.

01:05:27Okay, let me know.

01:05:29This is the third one.

01:05:31I will say this.

01:05:33This is the third one.

01:05:35This is the third one.

01:05:37Now, let me know.

01:05:39This is the third one.

01:05:41How many children can say buffer?

01:05:43Why not?

01:05:46Why did your brain come down?

01:05:48Why should your brain come down?

01:05:50I will say three conditions.

01:05:52Now look at how much you can twist it. How much you can twist it.

01:05:55That's the only thing you can do.

01:05:57It's a weak acid, it's a conjugate, it's a cation,

01:06:02which is a darsak, but it's a bay.

01:06:05It's a house. It's a house.

01:06:08It's a house.

01:06:10Let me tell you, it's a buffer or not?

01:06:12It's a buffer.

01:06:14What happens?

01:06:15You can play it.

01:06:16But you can twist it.

01:06:18If you have a mono acid, then it's a poly.

01:06:21What do you want?

01:06:22If you have a poly, next start.

01:06:24If you have a poly weak acid.

01:06:26Next start.

01:06:27If you have a poly weak acid.

01:06:29If you have a poly weak acid,

01:06:30If you have a poly weak acid,

01:06:33you can mix one hydrogen system.

01:06:35I'm taking H2CO3.

01:06:37If it is a 2CO3 and it is a dude,

01:06:40if it is a h2CO3 and it is a NOH,

01:06:43then it's a weak acid base.

01:06:45It's a 2 Deutschen reaction.

01:06:47What do you want?

01:06:48If I tertiary reaction,

01:06:50So, first of all, what can we do in front of us?

01:06:53We can get H2CO3 from one hydrogen.

01:06:56And one hydrogen from one salt has formed a form of NaCO3, which is called NaCO3.

01:07:01Tell me, first of all, this is a buffer or not?

01:07:04I will not repeat again.

01:07:07This is a buffer or not?

01:07:09What is the concept of a weak acid?

01:07:11It's a conjugate.

01:07:13And then, it's a cation.

01:07:17It's a reaction.

01:07:19This is a buffer or not?

01:07:20But, forget not to go, this salt is like hydrogen, which can come out.

01:07:26I said, this is like a salt, which is called Acetic.

01:07:29Can I say?

01:07:30Can I say hydrogen can come out?

01:07:33Can I say hydrogen can come out?

01:07:35This salt will be further reaction.

01:07:37And when it's further reaction,

01:07:39then, in front of you, my dear children,

01:07:41what will be the second compound?

01:07:43NaCO3 with NaCO3.

01:07:44NaCO3, I will say.

01:07:46I want to say, when will it be poly-weak acid?

01:07:48What is poly-weak acid?

01:07:49What is poly-weak acid?

01:07:50What is poly-weak acid?

01:07:501 minute.

01:07:51I have a concept.

01:07:51I will check.

01:07:521 minute.

01:07:52One minute.

01:07:53I said that all the children can be taken from the same time.

01:07:58Two of them are coming together and one-one.

01:08:01If the first hydrogen is coming together, then HCO3- will be taken?

01:08:05If the first hydrogen is coming together, what will happen?

01:08:08If the hydrogen is coming together, the acid is weak or strong?

01:08:10This is not the conjugate.

01:08:12It is the conjugate.

01:08:13It is the conjugate.

01:08:14The conjugate is weak.

01:08:15If the hydrogen is coming together,

01:08:18but you don't forget to leave it as the hydrogen is coming together.

01:08:21When the hydrogen is coming together,

01:08:23listen, if it is the respect of this, it is the base.

01:08:25If it is the respect of this,

01:08:27but if it is the hydrogen,

01:08:29the hydrogen is released.

01:08:30When the hydrogen is released,

01:08:32it will become carbonate?

01:08:33I will tell you,

01:08:34today it has HCO3- will be taken from the other side.

01:08:36If it is not acid,

01:08:39it will be the most weak.

01:08:41If the first hydrogen is coming together,

01:08:44the second hydrogen is more difficult.

01:08:46Do you agree or not?

01:08:47If the input has is with the solution,

01:08:50think of ourselves.

01:08:52If this is the solution rate via salt,

01:08:54the hydrogen is in AL plus.

01:08:56At last,

01:08:57the acid has been working on CO3-.

01:08:59This is like,

01:09:01I think,

01:09:03я tasks can behave Apple that as a red,

01:09:04But if it happens in regards to Dublin.

01:09:05It will become states that guitarатели.

01:09:07Pick up top,

01:09:09this can become so far,

01:09:10If you believe in the Cya- on the other side,

01:09:16I have a cation with cation.

01:09:18The water reaction is not done with the water.

01:09:20Sir, this one is not said, it's a cation.

01:09:22Sir, this one is not said, it's a cation with cation.

01:09:23Sir, this one said, the solution is in this,

01:09:25this and this, and this all together.

01:09:28Tell us, this is a buffer or not.

01:09:30So, today, we can create one buffer,

01:09:32and create two sets of buffer.

01:09:33So, when there is a poly-acid,

01:09:35it doesn't make a buffer,

01:09:36it is a set of buffer.

01:09:37What does it make?

01:09:38Next, it makes a star.

01:09:39In poly-weak acid, it is a set of buffer.

01:09:43Poly-weak acid, it is a set of buffer.

01:09:46So, it's a big love,

01:09:48that in any poly-weak acid,

01:09:50how many sets will become?

01:09:52So, it's how many sets will become?

01:09:55So, how many sets will become?

01:09:56Two.

01:09:57If there are three hydrogen,

01:09:58then three.

01:09:58So, let's make a rule.

01:10:00If any acid,

01:10:02any acid,

01:10:03which is a base city,

01:10:06any acid,

01:10:07which is a base city,

01:10:09which is a base city,

01:10:12which is a base city,

01:10:14which is a set of buffer,

01:10:17which is a set of buffer,

01:10:18which is equal?

01:10:19Is this clear or not?

01:10:21I have a question.

01:10:23I have a question.

01:10:25H2CO3,

01:10:26how many sets will become?

01:10:27S3PO4?

01:10:28S3PO4?

01:10:29S3PO2?

01:10:30S3PO3?

01:10:31S3PO3?

01:10:32S3PO3?

01:10:33S3PO3?

01:10:34S3PO3?

01:10:35S3PO3?

01:10:43comes down!

01:10:45Word it out!

01:10:46My dear school,

01:10:47my dear guys,

01:10:48many times,

01:10:49one thing happened happening here.

01:10:52What about this rule?

01:10:52One Schwartz system kiyaam?

01:10:54First

01:10:57will be able to do it with water, will be able to do other things as well.

01:11:01This is the question of the question.

01:11:03So, the question is,

01:11:05the question was,

01:11:06it was 4 options,

01:11:08although there wasn't any one thing in the chat.

01:11:10There were 4 options,

01:11:11but there were 1 option to know the buffer,

01:11:13which was very weird to know.

01:11:15What is the option?

01:11:16What is the rule?

01:11:18Let's move on to the next.

01:11:19So, I will leave the next point 5 star.

01:11:22Next point 5 star

01:11:23Next point 5 star

01:11:54all how many replaceable hydrogen is? How many set of buffer? Right? If I tell you,

01:12:01my first question, if I tell you, if I tell you, if I tell you, if I tell you, if I tell you,

01:12:09if I tell you, S3PO4 plus Na2HPO4, tell me is this buffer or not? How do you say?

01:12:17How do you say? You tell me, you tell me, how do you tell me? You tell me, you tell me,

01:12:21let me tell you, 1-bic acid, it's a conjugate, cation, cation, cation, cation.

01:12:27It's no matter, but the four options were, one option was this.

01:12:33S3PO4 plus Na3PO4. Hello? Na3PO, you understand? Let's go, I can tell you,

01:12:42what I have to do with this. I am going to give you an idea of this.

01:12:47Let me ask a question.

01:12:49I will give you an idea of the other one.

01:12:51The second one is occuring this by the way.

01:12:53I will give the negative one.

01:12:55What is重要?

01:12:56As well, the next one I will make it.

01:12:58The other one will give it,

01:13:01so that one is correct.

01:13:02Our question is not the same.

01:13:05It is the same and that,

01:15:53ऐसे डेख buffer की कहानी अगर कोई बच्चा अच्छा नहीं बोलता तो बोलना छोड़ देना वो क्यूं गंदा उगलते हैं जहर भी नहीं उगलते

01:16:13अगर आपने बोलना नहीं सिखा तो बोलना बन कर दो बेटा

01:16:24और क्लास का तो नियम है बोलना चुप चाप से पढ़ाई करिए

01:16:33पहले मैंने नियम बनाया था दान दिखाई आपके लिए वो भी नियम नहीं है आप चुप चाप से पढ़ाई करिए

01:16:42आपको बताना है इन में से कौन acidic buffer है और कौन acidic buffer इन इडाउट इन में से कौन acidic buffer है कौन acidic buffer नहीं है

01:17:00कि किसी को बुलाने से यह ठीक हो जाता है क्या है सच में हादे कर ऐसे टाइम वेस्ट कर लो सर्वड़ाता है न है

01:17:15पिटा चिर्कूट समझते हैं चिर्कूट लेगो जल दिसने

01:17:26जल्दी लिखे प्लीज प्यारे बच्चों आपके सामने मैंने कुछ

01:17:35combination लिखे हैं आपको इसमें पहचानना है कौन acidic buffer है और कौन

01:17:39acidic buffer नहीं है बहुत आसान सा खेल है बस उन सर्थों पर जीना है

01:17:44अच्छा अब आपके सामने जो solution है इनमें देखके पहचानना है केवल हमेशा इतना

01:17:56simple नहीं आएगा क्या-क्या modification सब बताऊंगा अभी फिलाल इसमें पहचानें

01:17:59समने कर लिया सुरू के 3-4-5 डिसकस कर ले बताऊ पहला वाला है कि नहीं है परफेक्ट दूसरा वाला सबसे बन गया

01:18:10weak acid है उसका conjugate है कैटायन है asdic buffer है असान है अगला वाला weak acid है उसका conjugate है साथ में कैटायन है

01:18:22नियम ऐसा नहीं था कि बस वहीं हो कहीं भी हो solution के अंदर तो कैटायन है ना यार मतलब यह rule मत बनाना है कैटायन वहीं बस हो यहां ना हो overall solution सब तूटा होगा बोलो ना यार

01:18:32तो solution में ऐसा कैटायन हो purpose क्या है कैटायन reaction ना करें तो आपने कैटायन भी worker ले लिया ना फिर खेल बिगड़ सकता है logic समझ पा रहे हो ना तो उसे मैंने सब्दों में ऐसे बोला एक ऐसा कैटायन हो जो पानी से reaction ना करें अरे हलो और वह च्छे के च्छे ही होने चाहिए च

01:19:02किसके ना होने पर यह होगा मेरा जो best option होगा मेरे हिसाब से तो H2CO3 प्लस NASCO3 ही होना लेकिन अगर कोई option नहीं हुआ माल लो सारे strong हो गए यह सा सवाल थापको मिलेगा PYQ में और मुझे मजबूरी में चुनना पड़ा तो फिर चुनूगा दूर का conjugate याद रहेगा ठीक है

01:19:32इतने बच्चे कह रहे हैं यह weak acid है कि strong acid है रूल एक weak acid होना अब ऐसा समझो ना मैं थोड़ा design बना के लिख दिया concept वही है मेरे प्यारे बच्चों यहां से क्या हटाया H plus और क्या चिपकाया K K मतलब potassium जो कि strong base से आया है एक weak acid होना उसका conjugate भी होना साथ मेकटायन भी होना ज

01:20:02हाँ ठीक है acid यहां H2S है यहां acid auxному Acid है आउं रुको यह आपके सामने potassium के अलावा देखो potassium के अलावा देखो

01:20:13But if you don't see, the result of potassium, in which you can see the same.

01:20:15You can see that.

01:20:17This is the potassium.

01:20:19Is it the conjugate?

01:20:21Potassium in which you can see the conjugate.

01:20:23But if you know that you don't know the acid,

01:20:25you can behave.

01:20:27So, do you think the acid is the weak acid.

01:20:31Or, it's the conjugate.

01:20:33But these two cation are different.

01:20:35So, what do you think?

01:20:37What do you think?

01:20:39this is when magnesium is a sodium or sodium is such a ion that we don't react to this.

01:20:45Then we don't do this.

01:20:47Now, there is no question.

01:20:49Yes, a buffer is not.

01:20:51This is the next question.

01:20:53If you have asked this question, write the next question.

01:20:58It will be the next star.

01:21:00The star will be the seven star.

01:21:02And A2, B4, O7.

01:21:09We call this borax.

01:21:13This is a compound.

01:21:17This is something that happens.

01:21:19This is a buffer or not.

01:21:21This is a concept that if you don't know the chemistry,

01:21:25then you can't do it.

01:21:27And the best thing is that if you don't come,

01:21:29you can't do it.

01:21:30But if you don't come,

01:21:31the last to last year was solubility.

01:21:33When you get these things,

01:21:35which you've never heard about,

01:21:37you don't have common sense.

01:21:38Now, A2, B4, O7 is a compound.

01:21:41Now, if I say borax.

01:21:43But if you don't come,

01:21:45if you don't come,

01:21:46if you don't come,

01:21:47if you don't come,

01:21:48if you don't come,

01:21:49if you don't come,

01:21:50if you don't come,

01:21:51if you don't come,

01:21:52if you don't come,

01:21:53if you don't come.

01:21:54You understand what?

01:21:55A2, B4, O7.

01:21:56Now,

01:21:57I'll tell you a fact.

01:21:58When you come,

01:21:59you come to the board.

01:22:00Come to the board.

01:22:01Come.

01:22:02Come.

01:22:03Come.

01:22:04Come.

01:22:05Come.

01:22:06As a different,

01:22:08As a different case.

01:22:10This thing must be better.

01:22:11Come.

01:22:13Yeah?

01:22:14Yeah?

01:22:15Take some.

01:22:171 Byrd.

01:22:18Do this.

01:22:19A1 odc.

01:22:20First of 5.

01:22:21Is it going?

01:22:22Come.

01:22:23Come.

01:22:24No question,

01:22:25see how it is going.

01:22:26See how we're going to?

01:22:27Your body are asking?

01:22:28All right.

01:22:29What?

01:22:30His body

01:22:31If we see the reaction of the borax, we need to know the reaction that we need to go to the borax.

01:22:38And we need to convert the boric acid into the borax.

01:22:41What is the question?

01:22:42What was the question?

01:22:43What was the question?

01:22:44What was the question?

01:22:45It was not the borax.

01:22:46Now, when borax goes to the borax, what is boric acid?

01:22:50What is the solution?

01:22:52Now, there is another compound that we call.

01:22:56We don't have to balance.

01:22:57Na, 2,O4 minus.

01:22:58S3,O3 acid is, yes.

01:23:01Acid is because it gives H plus iron and because it accepts OH minus iron.

01:23:06I said, I didn't say that.

01:23:08I will say that in S3,O3.

01:23:11Here is the vacant pure vital.

01:23:13H plus iron is not.

01:23:14H minus iron is not.

01:23:15It is not.

01:23:16It is not.

01:23:17In Arrhenius's definition, it was H plus.

01:23:20In Arrhenius's definition, H plus is S per NCRT.

01:23:23But in extended version, H plus is OH.

01:23:26Orlando.

01:23:27Is this, OH minus iron and H again?

01:23:29This is.

01:23:30Do you want this OH minus iron?

01:23:31Do you know this?

01:23:32That doesn't mean such a simply.

01:23:33Not.

01:23:34We don't hear the kuvio acid like pore radio.

01:23:36It is.

01:23:37Sooo this is the bottom line?

01:23:38There.

01:23:39reaction के अंदर क्या है यह हाँ यह तभी जानोगे जब reaction पता तो अभी आपने पूरा

01:23:43IOC नहीं पढ़ा है धिर जब पढ़ोगे जान जाओगे लेकिन मैं कह रहा हूं अगर reaction पता है

01:23:47मान लो तो क्या अब आप बता सकते हो बफर है कि नहीं है एक वीक असट हो ना उसका

01:23:54conjugate भी हो ना सर ने यह कब कहा conjugate हमें साइस प्लस वाला चलेगा अरे यह

01:23:59वाट इस कॉंजुगेट इस्पिसीज हाविं डिफरेंस और वन एच प्लस और बोलो ना यार वह

01:24:06कॉंजुगेट है कि नहीं है है तो एक वीक असट होना चाहिए उसका

01:24:10कॉंजुगेट भी होना चाहिए साथ में कैटायन भी होना जो पानी से रियक्शन नहीं करना बोलो यह बफर है कि नहीं है और कौन सा बफर है

01:24:20इस दस क्लियर और नॉट तो प्यारे बच्चों हमें बफर पहचानना अना चीस में स्टार्ड लगा देना एजड़ केस दिमाग में रखना पड़ेगा बहुत पुराना सवाल था चलेगा चलेगा बाई मैं आपको होमग दे दिया है तो बेल हो गई कि अपनी ठीक है आप

01:24:50और आपको पता है बहुत सिंपल सा खेल है जो सिलिबस उसे कंप्लीट करो सवालों की प्रैक्टिस करो जिस सब्जक्त में डाउट है टीचर से पूछो लेकिन मेहनत करो that's all for today मिलते इस क्लास में थैंक यू सो मच
