00:00:00and class can link I will share you in Telegram.

00:00:03You can click on this link and then where the link goes,

00:00:09it will go, it will come.

00:00:12First of all, next class can homework.

00:00:19Today until it happened,

00:00:21it will be good to revise.

00:00:27If you have done it,

00:00:34if you have done it,

00:00:37if you haven't done it,

00:00:39please do it.

00:00:40Then you will ask ELP number 9,

00:00:431, 9, 10.

00:00:47Then you will ask ELP number 10,

00:00:522, 3, 4, 5.

00:00:566, 11, 12, 13, 13 and 14.

00:01:06Then you will ask exercise 1.

00:01:09Exercise 1,

00:01:11which you have done before,

00:01:13there are 4 questions.

00:01:1580 to 84.

00:01:16Then you will ask exercise 3.

00:01:19In exercise 3,

00:01:20there are very good questions.

00:01:22This is a good question.

00:01:24this question.

00:01:251, 2, 1, 2.

00:01:26It is a good question.

00:01:271, 2, 1, 2, 2, 1, 2, 3, 3, 4, 3,

00:01:311, 2, 2, 3, 1, 2, 3, 4, 3, 4, 3, 2, 3, 2, 3, 3, 2, 3, 4, 3.

00:01:33This is all you can do when you have a question, when you have a question, your confidence is high, then you can do it with exercise 2.

00:01:4239, 40, 42, 60, 61, 64, 65, 87, 89.

00:01:53If you do it with exercise 2, then you can do it with exercise 4.

00:02:00In exercise 4, you have to do it with exercise number 22, the number 30, the number 31.

00:02:08If you are making this fun, you think that the value of your spending is the amount of money.

00:02:23। । । । । । । । ।

00:02:53। । । । ।

00:03:22। । ।

00:05:02And so with the big sharp light, you should all modomy increase in a very short part.

00:05:05So once again, one charge, you should have 0.1 mole.

00:05:09How much, 0min micromer ночihow?

00:05:11And then you could try to plan before the output is 1000 to 6, 개�otti.

00:05:14You could be 50.9 instead.

00:05:15Now tell yourself what much.

00:05:16How much before the output is aso, which is the first one?

00:05:19Quite the point?

00:05:20The logic and the concept is very simple.

00:05:24Theopia is where low is instead instant.

00:05:26That here protecting the output doesn't work.

00:05:29Then you see the way.

00:05:30Whole everyone does.

00:05:48a

00:05:50big

00:05:53than

00:05:55the

00:05:56question

00:06:00that

00:06:01it is a mathematical term to measure effectiveness of a buffer, to measure effectiveness of a buffer.

00:06:30किसी भी buffer का, effectiveness ना अपने का, एक mathematical concept है, buffer capacity, सरी होता क्या है, लिखेगा second point,

00:06:39it is the ratio of, number of moles of, SA और SB added, SA और SB added to pH change,

00:06:54to pH change, अगर मैं इसे, एक formula के सक्ट में लिखना चाहूं, तो कुछ ऐसे लिखोंगा मेरे प्यारे बच्चों,

00:07:01जो buffer capacity है, जो buffer capacity है, इसका मतलब है, कि आपने कितने SA या,

00:07:09SB के mole मिलाए, और उसमें से कितना pH का change आया, आप उन दोनों का ratio निकाल दो,

00:07:16वो जो ratio है, उसे ही नाम दिया गया buffer capacity, उसे ही नाम दिया गया buffer capacity, अगर एक बच्चा numerically सोचे, तो ऐसे सोचे, कि सर हमें SA और SB के mole बताएंगे, वो mole और pH के change को हम divide कर देंगे, हमें क्या मिल जाएगा buffer, बच्चों, एक छोटा सा common sense का सवाल पोशता हूँ,

00:07:37pH change denominator में है कि numerator में, तो अगर pH change कम होगा, तो buffer capacity, बोलो, ये दोनों directly है कि inversely, यानि मैं ऐसा भी कह सकता हूँ, कि buffer capacity जादा, buffer capacity, यानि pH में change, तो buffer अच्चा की बुरा, buffer अच्चा, तो buffer action जादा, बोलो हाया ना,

00:08:00तो यहां से एक rule बन गया, एक concept बन गया, concept ये बना, कि buffer capacity किसी भी solution का जितना जादा, तो buffer action उतना जादा, और buffer action होगा जादा, तो बताओ buffer अच्चा की बुरा, अच्चा, बोलो, डन, अब आप जब बजार जाते थे, तो pH range भी नहीं पूछते थे,

00:08:26सीधे कहते तो भाईया buffer capacity बताओ, वो कहता था इसकी 5, इसकी 10, इसकी 15, जिसकी buffer capacity सबसे ज़ादा, वो buffer सबसे, बोलो, डन, हमने सीखा क्या, हमने ये सीखा, कि buffer है क्या, हमने ये सीखा, कि कौन सा buffer अच्चा है, कौन सा buffer, उसको समझने के दो पैमाने है, या तो pH range से देख �

00:08:56buffer capacity, चलेगा, एक सवाल लिख लो जरा, तो प्यारे बच्चों, यहां से सिलसला सुरू होने वाला है सवालों का, और मैंने आते ही कहा है, आज की जो class है, as per I need equilibrium, the conclusion of all the class, जितना भी तक आपने पढ़ा है, और सारे mix सवाल चलने वाले हैं, चलेगा, सबसे पहले, इसी topic का स�

00:09:26If two solution A and B are having buffer capacity of 10 and 20 respectively, then which buffer solution will be having maximum buffer capacity?

00:09:56Sorry, will be having maximum buffer action, which buffer solution will be having maximum buffer action?

00:10:05बच्चों, buffer capacity अलग चीज है, buffer action अलग चीज है, हाँ यह बात अलग है कि buffer capacity ज्यादा, तो buffer action भी, क्या सब को buffer action का मतलब पता है?

00:10:19जब भी buffer action बोलना होता था, सर बोलते थे buffer यत, क्या बोलते थे?

00:10:24तो सायद, मैंने buffer action को एक कोड़ वर्ड ने बोला था, जिसको बोला था, buffer यत बोलो हाँ या ना, buffer capacity ज्यादा, यानि buffer में change ना होने देना, pH में change ना होने देने की capacity ज्यादा, तो buffer अच्छा, तो buffer action,

00:10:40simple ता सवाल, अगर यह fact पता है, तो क्या बन जाएगा? A solution की buffer capacity कितनी है? 10, B की कितनी है? 20, कौन सा नंबर बड़ा है? 20, तो buffer capacity ज्यादा, तो buffer action ज्यादा, तो क्या answer भी हो जाएगा?

00:10:54अब सोचो, अगर यही सवाल, मैं थोड़ा सा numerical अंदाज में लिखता तो कुछ ऐसे भी लिख सकता था, लिखो, यह असान है भई, अरे असान है न, दो नंबर है कौन सा, किसकी छमता ज्यादा, सर 20 वाले की, तो कौन अच्छा buffer, सर 20 वाला, कहा buffer action ज्यादा, 20 वाला, अरे simple

00:11:24buffer capacity of a solution, if buffer capacity of a solution is 10, एक solution है, उसकी buffer capacity कितनी है, 10, then calculate, then calculate, pH change, then calculate, pH change, if, if 0.1 mole,

00:11:49of a, is added to the solution, is added to the solution, सभी बच्चा सवाल समझ गया, एक solution है, उसकी buffer capacity, 10 है, और सवाल मुझे कहता है, कि बताओ, उसमें pH का कितना change आएगा, अगर हमने, बोलो प्यारे बच्चों, कितना मिलाया है, 0.1, आसान है,

00:12:17फॉर्मॉले से करना चाहते हैं, तो फॉर्मॉले से करें, नहीं तो फील भी आपके सामने है, तो अभी मैंने आपको buffer capacity का formula क्या बताया था,

00:12:24मोल्स आफ ऐसे एड़र अपन पी एच चेंग, क्या मुझे buffer capacity दे रखी है, यह सर्, क्या मुझे मोल्स आफ ऐसे दे रखा है, यह सर्, क्या हम से pH चेंग पूचा है, यह सर्,

00:12:38so what will be the pH change, आरे, simple सी बात है यार, 0.01, बताओ यह change है, कि बहुत थोड़ा change है, और ऐसा buffer जिसमें इतना मामुली change आ रहा है, सायद उसे अच्छा buffer माना जाएगा, कहानी को समेटते हैं, और धेर सारे सवाल करते हैं, चलेगा,

00:12:55point number one, क्या सबको buffer clear है, मैं बोलूँगा, आप सुनते रहिएगा, right, एक ऐसा solution, एक ऐसा, जिसमें थोड़ा सा, थोड़ा सा, भर भर के, लेकिन pH में कोई खास change, क्या यही solution buffer कहलाया, अगर कोई buffer होगा, तो buffer का buffer action होगा,

00:13:15buffer action का simple सा मतलब है, H plus को consume करना, O H को consume करना, फिर से release नहीं करना, यही कहलाता है buffer action, हर buffer का buffer action होगा,

00:13:27buffer action जितना ज्यादा, buffer उतना अच्छा, बोलू आसान है, क्या हमारे सामने तीन प्रकार के buffer थे, एक ऐसा buffer था, जो एक ही substance से बना था, और एक ऐसा buffer था, जो mixture से बना था,

00:13:45एक था, क्या सबको याद है, तीनों की condition याद है, कौन सा solution है, याद है, तीनों का pH याद है, pH range याद है, इस पूरी कहानी में बस दो बात याद रखना, अगर कभी कोई सवाल आएगा सबसे पहले solution पहचाना, और अगर reaction होती है, तो reaction कराईए, सबसे पहले बनने वाले solution का

00:14:15स्ट्रॉंग होगा, तब तब reaction कराया जाएगा, शुरू करें सिलतला सवालों का, पहला सवाल, अच्छा, हर सवाल को सीखने कोशिस करना, सारे सवाल standard है, और हो सकिन सवालों को दुबारा लगाना पड़े तो लगाईएगा, चलेगा, लिखिएगा, पहला सवाल, calculate the pH of, calculate the

00:14:45HcN solution, HcN solution, present with 10 की पावर माइनस 3 मोलर, KcN solution, present with 10 की पावर माइनस 3 मोलर, KcN solution, if Ka of HcN, is 10 की पावर माइनस 6,

00:15:09HcN का हमें के दे रखा है, और उन्होंने हमसे solution का pH पूचा है, रुको, कोई भी सवाल आएगा, सबसे पहले step क्या सोचेंगे, सबसे पहले solution को पह है, मुझे ये method आपके दिमाग में sit करना है, ना क्यान से निकलवाना सिखाना है, समझिएगा, ये chemistry है, और chemistry में भी आईव

00:15:39बताओ, आज reaction होगी कि नहीं होगी, सिंगल है कि make sure, तो reaction हो सकती है कि नहीं हो सकती, reaction की condition बोलो, acid होना, base होना, ये base है कि नहीं है, तो पहली condition तो fail हो गई, अब दूसरी में आओ, एक वरकरायन होना, मगर strong में होना, और साथ में दूसरा भी strong होना, तो strong तो है, लेकिन दू

00:16:09जो है, जो होना है हो चुका, अब कोई reaction होने वाली, अब बताओ, ये जो solution है, क्या ये weak acid है, अचा रुको, आपने कितने solution पढ़ें, या तो होगा single, या तो होगा mixture, या तो होगा mixture में भी, या तो pure salt होगा, या तो salt के साथ कुछ होगा, तो कुछ था, तो buffer ही तो बना था,

00:16:39condition है, बोलो ये buffer है कि नहीं है, तो सबसे पहले solution को पहचाना, अब buffer है, तो आप से पूछा क्या है, तो formula किसका लगाओगे, लगाईए pH का formula आपको देता हो, 30 से 40 seconds सभी बच्चे solve करे, आंसर बोलना नहीं है, बस रूल रहेगा, पहला सबसे सिंपल, करते चलिए फटा-फ�

00:17:09मैं क्या बोल रहा हूँ, समझ पाए, हर buffer की अपनी pH range होगी, जरा मुझे बताओ, इसका k कितना है, 10 के पावर, minus 6, तो इसका pH range, pH range, pH range, 5 to 7, right, चलिए, लगा लिया formula, लगा लिया formula, सबसे पहले pH का formula, pH बराबर pk plus log, concentration of conjugate iron, upon weak acid, बोलो डन,

00:17:39क्या हम pk निकाल सकते हैं, pk यानि की minus log of k, सारी value को रखिए, salt करिए, कितना आएगा, 6, अब यहाँ चलते हैं, log, conjugate iron, मैं हमेशा कहता था, conjugate iron, हमेशा strong से ही आएगा, conjugate iron, हमेशा strong से ही, इस concept को मैंने salt में already सिखा दिया,

00:17:59और वहाँ मैं कहता था, concentration हमेशा उस iron की लिखेंगे, जो पानी को तोड़ेगा, जो पानी को, जो पानी को, मुझे बताओ, क्या आज यहाँ पे strong ये है, क्या ये पानी को तोड़ेगा, तो क्या मुझे इसकी concentration लिखनी है, जो salt की concentration है,

00:18:17वही cyanide की concentration है, क्योंकि KCN जो पानी में टूटेगा, तो K plus और CN minus बनाएगा, एक छोटा बच्चा भी समझ सकता है, एक मुल जाएगा तो एक मुल ही, तो कितना है वो, 10 की power minus 3, तो वो कितना होगा, 10 की power minus 3, यानि प्यारे बच्चों ये कितना, 10 की power minus 3, 10 की power minus 2, एक एक स्�

00:18:47पाइन पर है कि नहीं है, ये passing mark से pass हुआ है, क्या अच्छे से pass हुआ, इसका pH range क्या 5 तो 7 होना था, जादूई buffer तो तब होता, जब इसका pH 6 होता, बोलो डन, एक सवाल पूछने का मन करा, पूछ लूँ, जादूई buffer होने की condition क्या है, जो concentration, जादूई buffer होने का pH बराबर प

00:19:17जब जब concentration अलग होगा, तब तब वो जादूई buffer नहीं होगा, बोलो डन, बोलो डन, दे दूँ अगला सवाल, लेखो जड़ा, ये सब को clear है, चलिए, सवाल करोगे तो सीखोगे जो सिखाने वाला हो, right, please, formula लगाना है, answer पाना है, बढ़ूँ आगे, calculate, calculate the pH, calculate the pH of resultant solution, calculate the pH

00:19:47of resultant solution, which is formed, which is formed by mixing, which is formed by mixing 60 mg acetic acid, which is formed by mixing 60 mg acetic acid, and 20 mg NaOH,

00:20:10which is formed by mixing 60 mg acetic acid, and 20 mg NaOH, to prepare a solution of 10 liter, to prepare a solution of 10 liter, total volume कितना दिया है,

00:20:31if Ka of acetic acid is 1.8 into 10 की पावर, minus 5, if Ka of acetic acid is 1.8 into 10 की पावर, minus 5,

00:20:50रुको, रुको, कर लोगे, मैं समय दूँगा, मुझे step number one, कोई भी सवाल आएगा, reaction होती है,

00:20:57तो reaction, सबसे पहले बनने वाले solution का पता, सर ने reaction की मात्र दो ही condition बताई,

00:21:03इतनी बड़ी आयोनिक, उसमें केवल दो condition, ये तो याद कर लो बेटा, इतनी बड़ी chemistry की दुनिया,

00:21:10मात्र दो condition में summarize किया है, वो तो याद करो, या तो acid base होना,

00:21:14या तो कोई वरकर आयन होना, जो कि strong में होना, और साथ में कोई दूसर भी strong होना,

00:21:19चाहिए, बोलो दोनों acid base हैं की नहीं है, reaction होगी की नहीं होगी,

00:21:24कराईए reaction बनने वाले solution का पता लगाईए,

00:21:28समय देता हूँ पूरे एक मिनट, आज आपको करना है, आपको सीखना है,

00:21:49क्या बात है, answer आ चुका है, आप सब के बीच में, दो बच्चों के,

00:22:14तीन, मैं तो पूछ भी नव, answer क्या आया है, मैं तो चाहता हूँ पहले आना तो सुरू हो, सही तो होई जाएगा,

00:22:25चलिए, step number one, क्या समने reaction करवा लिया, चेक करते, जो बच्चा बिलकुल नहीं कर पाया,

00:22:30पहला कदम बढ़ाईए, पहला कदम बढ़ाईए,

00:22:32C-S-C-O-H, प्लस N-A-O-H, बोलो क्या बनेगा, C-S-C-O-N-A, प्लस पानी, बोलो डन, मुझे बताओ, इसके कितने मिलिग्राम, और इसके कितने, तो मैं 20 भेज़ दू, 40 बचेगा, 0 बचेगा, कितने बच्चों ने ऐसा किया,

00:22:50किसे ने किया होगा, अरे किया होगा, बताओ गरबड क्या हुआ, Istoichiometry, मोल बताती है, Istoichiometry weight नहीं बताती है, आप कभी भी reaction weight में नहीं कराते, weight में कराते इतनी बड़ी chemistry का जन्मी नहीं होता, अरे हाया न, फिर तो कितना असान होता, 10 ग्राम रियक्टर्न का, 10 ग्राम इस

00:23:20।

00:23:50Hello, one mole is 1 millimole, because I have a weight in gram.

00:23:57Mole is what is weight in gram.

00:24:00So if I write gram, then 10 to minus 3 is what I have.

00:24:05If I don't write, then I write simply 1 millimole.

00:24:08If I write a gram, then I write a gram.

00:24:11Then I write a gram.

00:24:13If I write a gram, then it is not a gram.

00:24:16Where the gram is 10 to minus 3, where the gram is 10 to minus 3,

00:24:20where the gram is 1 millimole.

00:24:20It's going to be.

00:24:21Now, I will tell you, I will tell you,

00:24:22I will tell you, how many of these are going to be?

00:24:23I will tell you, how many of these are going to be?

00:24:2820 by 40, how many will be?

00:24:30Half.

00:24:30Millimole.

00:24:31I will tell you.

00:24:32Now, start with questions.

00:24:34How many of these are going to be?

00:24:37And then, I will tell you.

00:24:39Then, I will tell you, 30-40 seconds, start with questions.

00:24:42I would like to ask you all questions.

00:24:44Because we have the last question to reach your questions.

00:24:45Which is interesting.

00:24:46What is the answering answer?

00:24:51Pretty answer?

00:25:00Check it out.

00:25:01I will tell you.

00:25:01It was not going to be.

00:25:01But it is not going to be.

00:25:02You know how many of these are going to be.

00:25:07this is not a good one.

00:25:09So,

00:25:10t equals 0

00:25:11is the number of millimoles

00:25:13and the number of millimoles

00:25:15are the number of millimoles.

00:25:17Let's go.

00:25:19If it's 0.5

00:25:21and it's 0.5

00:25:23will be done.

00:25:25So,

00:25:27how much will it be?

00:25:29Now,

00:25:31here,

00:25:33how much will it be?

00:25:35Rule for revise.

00:25:37Step number one.

00:25:39First of all,

00:25:41reaction.

00:25:43Reaction.

00:25:45As a SB

00:25:47salt.

00:25:49So,

00:25:51how much will it be?

00:25:53Now,

00:25:55it will be done.

00:25:57What's the same?

00:25:59This is what is called Acetic Acid, which is salt.

00:26:06What is called Acetic Buffer?

00:26:11So, what is the formula?

00:26:13What is the formula?

00:26:15What is the formula?

00:26:17Let's go.

00:26:18So, my children, I will put the formula in the formula.

00:26:20All right.

00:26:21So, my children, I will put the formula in the formula.

00:26:24A plus log.

00:26:25Concentration of conjugate upon weak.

00:26:29Bolo done.

00:26:30Koi mujhe pk solve karke bata saktahe?

00:26:33Banja kya?

00:26:34Mijn idhar solve karraho.

00:26:35So, pka is equal to minus log of 1.8 into 10 ke power minus 5.

00:26:41Chun-chun ke log yad karae thae.

00:26:43Kaya sabko log 1.8 yad hai?

00:26:450.26.

00:26:47So, 5 minus 0.26.

00:26:494.74.

00:26:50Bolo done.

00:26:51Kya mery pk ki value a gai?

00:26:54Pk kitna aya?

00:26:554.74 plus log.

00:26:57Ajao jarah.

00:26:58Conjugate iron ka concert bolo lenge.

00:27:00Conjugate iron.

00:29:43chalo chhođo

00:29:45jambi aap ko equilibrium पढ़ा रहा था तो मैं हमेसे एक line कहता था सबसे पहले reaction को खींच की क्रियम पर लाना याद है given information

00:29:53से compare कराना वो गाना फिर से गाना वो एक rule का वो एक मंत्र था जो पूरी equilibrium का था चीक उसी प्रकार से आयनिक का मंत्र है क्या सबसे पहले

00:30:03solution को पह है सबसे पहले solution को पह है reaction होती है तो reaction आप मुझे बताओ जो

00:30:10substance है single है कि mixture तो reaction होगी कि नहीं होगी कितने बच्चे कहरे reaction होगी reaction हो नहीं

00:30:17condition बोलो एक बार याद करो ना एक बार एसे नहीं acid base हो ना acid है है क्या कोई base है तो पहली condition

00:30:27cross अब दूसरी में आओ ऐसे नहीं छुन लो एक बार एक बढर सुन लो कोई worker आयन हो कोई

00:30:34worka strong में हो को कोई और साथ में strong भी हो और हाया ना strong में हो

00:30:45strong भी हो strong में हो strong भी हो या दो गया बताओ reaction होगी कि नहीं होगी मतलब पका-पका या

00:30:53to maintain to maintain a constant to maintain

00:31:22a constant pH of 9

00:31:25to maintain a constant pH of 9

00:31:28रुको, सबसे पहले वहम तोड़ दूँ, आधी जनता को तो यह नहीं पता है

00:31:31उन्हें लगता है, acidic buffer का pH साथ से कम होगा

00:31:34यह buffer है कि नहीं है

00:31:36acidic है के basic है

00:31:38इसका pH साथ से कम होना चीए कोई जरूरी है

00:31:41आपके सामने मैंने कितना pH लेखा है

00:31:43तो पहले दिमाग से वहम हटा दो

00:31:45acidic salt का solution, acidic हो कोई जरूरी

00:31:47acidic buffer का solution, acidic हो कोई जरूरी

00:31:50अले हलो, आधे AR यहाँ पर गलत हो जाएंगे

00:31:54नाम acidic है, लेकिन solution acidic है कोई जरूरी

00:31:56सुरू हो जाईए

00:31:57लगाईए formula, पूरा समय लीजिए

00:32:00करके बताईए

00:32:01हो सकता है, बन जाए

00:32:03समाल अगर

00:32:08force की बाते करेगा तो force का formula लिखोगे

00:32:10pH की बाते कर रहा तो pH का formula लिखो

00:32:13लिखो, किसी बच्चे का अंसर भी आ चुका है

00:32:16बोलेंगे

00:32:17चलो, जो बच्चे नहीं कर पाए

00:32:31step number one, क्या सबसे पहले solution को पहचाना

00:32:34ये buffer है कि नहीं है

00:32:36चलो साब, ये वाला level तो cross हो गया

00:32:38पहला साब, cross

00:32:40सबसे पहला साब तो यही होता है

00:32:41बच्चा solution गलत ना पहचान ले

00:32:43दूसरा साब, अब सवाल किस की बाते कर रहा है

00:32:45volume, volume, लेकिन कुछ pH बोला है कि नहीं बोला

00:32:48तो buffer आती है आपको pH का formula याद आएगा

00:32:50आप बताओ, pH का formula याद दूआ कि नहीं याद दूआ

00:32:53बोलो, pH बराबर

00:32:55प्लस लॉग, concentration of conjugate

00:32:58upon conservative

00:33:00अब रुख जाओ, यहाँ मोल भी लेक

00:33:02मिली मोल भी लेक

00:33:04ग्रामिक प्रेंड भी लेक

00:33:06मिली ग्रामिक प्रेंड भी लेक

00:33:08अरे बोलो नया, दिमाग लगाओ

00:33:10अगर हम कुछ भी लिख सकते हैं तो सवाल में

00:33:12जो information given है

00:33:14information क्या volume और molarity की है

00:33:17बोलो नया, सुनो, सुनो

00:33:19क्या मैं यहाँ सीधे वी कैसे 2 molar लिख दूँ

00:33:21और क्या मैं यहाँ 5 molar लिख दूँ

00:33:23अब दिमाग लगाओ, अगर मैं 5 molar लिख दूँगा

00:33:26तो जो उसने पूछा है वो आएगा कैसे

00:33:28जो उसने पूछा है वो

00:33:30तो सीधे लिख दूँगा फिर तो सवाली नहीं हुआ

00:33:33मतलब मुझे कुछ यहीं पे खेलना है

00:33:35हाँ या ना, क्या उसने मुझे से वॉल्यूम पूछा है

00:33:37मतलब मुझे यहाँ कुछ ऐसा लिखना है

00:33:39कि वॉल्यूम आ जाए

00:33:40क्या जाए, रुको जरा

00:33:42क्या सबको मॉलाइटी का फॉर्मला याद है

00:33:44बोलो M बराबर N बाई V

00:33:47तो N बराबर M इंटो V

00:33:50क्या यहाँ मॉल लिखने की पर्मीशन है

00:33:52और अगर मॉल लिखने की पर्मीशन है

00:33:54तो फिर मॉलाइटी इंटो वॉल्यूम लिखने की भी

00:33:56पर्मीशन है

00:33:57फिर से ट्राई करो

00:33:59मैं चाहता हूँ आज आप सवाल करे

00:34:01जिनका अंसर आगया अच्छी बात है

00:34:06I'm doing.

00:34:12I'm not saying that the 8 is correct or the 2 is correct.

00:34:15I'm saying that it's good, then the first is correct.

00:34:19What do you say? 12 is correct.

00:34:24What do you say?

00:34:26Now, this is how simple you play in this.

00:34:29Let me know how the formula is linked.

00:34:31Let me know this.

00:34:32This is where I know, this is where I know.

00:34:35नी पता नहीं लेकिन निकाला जाओ allerdings जो जो पता है लिगदो

00:34:40जो जो नहीं पता कोज में निकल पड़ो है हरे हलो चलिए साफ समय समाथ होता हुआ

00:34:46अगला सवाल करना टाइम सब अगला करना अभी तो सवाल शुरूब भी नहीं वगा आ

00:34:50I'll go get some kind of work

00:47:16What do I have done?

00:47:17K is 10 to power minus 6.

00:47:19Concentration is 2 into 10 to power minus 2.

00:47:21Go, say it's wrong.

00:47:27Bhol may not know.

00:47:28This is mole.

00:47:30Buffer has no difference.

00:47:32Here is the difference.

00:47:33There will be the mole.

00:47:34The mole will write the name here.

00:47:36Here will be the concentration.

00:47:37There will be the concentration.

00:47:38And concentration will be the volume.

00:47:40Divide will be the volume.

00:47:41Here will be the volume.

00:48:11I don't think I'm going to do it I don't think I'm going to do it I don't think I'm going to

00:48:30in the class of 11 years later the question is the one who does it?

00:48:35and the question is the total of 600 questions in the class and the question is the one who

00:48:42has answered question is the one who has answered question?

00:48:48what should be the concentration so concentration kiska nikala axion ka the mole but a volume

00:48:56mole kitna 0.02 or volume kitna hai thus so it comes out to into 10 ki power

00:49:06hiya na shall yeh saab yeh a chuka hai concentration or isko karengi sol to batayyeh

00:49:13kitna answer ayega 10 ki power minus 6 into 2 into 10 ki power minus 3 karloge sol

00:49:21me kar djeta hoon sol karne pyaayega 2 into 10 ki power minus 9 ab joh bachis ko nahi

00:49:28karpaate unke leye dekho kaisa karna hai dekhlo eek baar aray hum log force nikala dhe catch plus

00:49:32yahaan a chuka hai 2 into 10 ki power minus to 10 se multiply 10 se

00:49:38or 10 ki power minus 9 chalega to 10 to 20 upon 10 upar ya minus 10 right so

00:49:51loghe to bolu kitna aya ga hai hai hai hai hai hai hai hai hai hai hai hai hai hai hai hai hai hai hai hai

00:49:57तो concentration of h plus कितना आएगा four point चलो छोड़ो सोचते हैं into 10 ki

00:50:08a reference का से होगा

00:50:09यह क्यों उसको करूंगा तो नहीं होगा

00:50:23कि बुलेंगे answer कि अंडरू बता रहे हो पीएच बता रहे हो एक बच्चे का answer है four point four eight

00:50:36कि वो बता रहे जिनको अपने answer का पता नहीं है अच्छा आ रहा है अभी ठीक है भाई चलो तो हाँ

00:50:45कि अब हमें अंडरू ट्वंटी सॉल करना रुको अगर 16 होता तो कितना होता और पच्चीस है कि यह सोले है कि पच्चीस है कि बीस है तो यह है बीचो बीच तो आप भी आ जाओ

00:50:57अग्याँ है समझभा रहें क्या और जब आप बीचों भी चाहें कित्रा है इंगा 4.4 लिखने सा डर लगता 4.4 लिखें लिघ लो

00:51:08Ты led me to do citation By Alice in general and you should try to post it left

00:51:20to learn more about this.

00:51:23Right now it's the 5th

00:51:25you already think about each level means logical

00:53:03Hello, because you have 6, whatever you want to do, I have 6.

00:53:07I have 6.

00:53:08So, you can say something new name.

00:53:10It's not a simple concept.

00:53:11Let's write a question.

00:53:13Let's write a question.

00:53:14In the next question,

00:53:15there is a question.

00:53:17What is the difference between today?

00:53:19Cacian is 0.01

00:53:22and HCL is 0.02.

00:53:29Mole.

00:53:300.02 mole.

00:53:33This is a mole.

00:53:35This is a mole.

00:53:37Volume is 10 liters.

00:53:38And K of Cacian is 10-6.

00:53:41If I want to save you,

00:53:44Volume is 1 liters.

00:53:46I will give you a question.

00:53:48But I want to say,

00:53:51where there is concentration,

00:53:53where there is concentration,

00:53:55where there is concentration.

00:53:56In the buffer there is no difference.

00:53:58But in the other places,

00:54:00there is a difference.

00:54:05Step number one.

00:54:06First of all,

00:54:07the solution.

00:54:09I have noticed the solution.

00:54:10What is the reaction?

00:54:11What is the reaction?

00:54:12Yes sir.

00:54:13What is the one?

00:54:14It will be.

00:54:15If I have done this,

00:54:16I will cover it.

00:54:17One time,

00:54:18let us cover it.

00:54:19So,

00:54:20KCN plus HCL,

00:54:21HCl, when reaction becomes HCl, HCl plus KCl, right?

00:54:31T equals 0, KCN.

00:54:33How many more is this?

00:54:340.01, this is 0.02, this is 0.02, this is 0.01, this is 0.01, this is 0.01.

00:54:45The first thing is, if you have questions, if you have any questions, don't do any questions.

00:54:51The answer is not the answer, the answer is the synchronization.

00:54:55When you have a discussion, or you have seen it in the rhythm,

00:54:59which is not the same, so never do it, please.

00:55:02This is the school paper.

00:55:04You will have to learn a step, but if you are desynchronized,

00:55:08then you will have to learn the board.

00:55:10This is the most important problem.

00:55:12We have to keep the dependency here.

00:55:14Let's go.

00:55:15I am going to tell you, today is KCL.

00:55:18The rules are always saying that

00:55:20the first thing is the solution.

00:55:22There is a reaction.

00:55:24The reaction?

00:55:25The water, the SASB, the SASB.

00:55:28Let me tell you, today is the solution.

00:55:32Now ask yourself, who are these two?

00:55:34One is HCN, and one is HC.

00:55:37This is the weak acid or not?

00:55:39This is the strong acid or not?

00:55:41Sir said that whenever the weak acid comes,

00:55:44the strong will go.

00:55:47One thing is correct.

00:55:49This is the main case sheet.

00:55:50This is

00:56:01which you must force the consumer and you can filter out.

00:56:01I sensualize these two.

00:56:02Other�� the��logic side cts.

00:57:30I will give you a question, I will give you a question, I will give you a question and write a question.

00:57:39I will give you a question, write a question, calculate the pH, there will be no answer.

00:57:45Calculate the pH of resultant solution which is obtained by mixing 200 ml of 0.01 mol.

00:58:14NH4OH with 200 ml of 0.01 mol.

00:58:39HCl solution, if Kb of NH4OH is 10 raised to the power minus 5.

00:58:57If Kb of ammonium hydroxide is 10 raised to the power minus 5.

00:59:02I will give you a question, I will give you a question, first of all, one component is more than one.

00:59:09Rule number one, if there is a reaction, if there is a reaction,

00:59:14condition, condition, condition, acid base,

00:59:16how do you know, acid base or not?

00:59:18So, reaction or not?

00:59:20Start, reaction, check,

00:59:22what will happen, what will happen,

00:59:23what will happen.

00:59:24What will happen,

00:59:25what will happen,

00:59:26what will happen,

00:59:27the question,

00:59:28what will happen,

00:59:29this question,

00:59:30you will give me a question.

00:59:31I don't know.

01:00:01So the answer will come, then the answer will go away.

01:00:05Think about it, think about it, think about it, think about it.

01:00:12First of all, the first solution, let's go.

01:00:15Step number one, all children will do it.

01:00:17I will not check the copy, I will not do it.

01:00:20If I want to learn two steps, three steps, when will it become?

01:00:23I will not know.

01:00:24All of you have a reaction?

01:00:26Tell me, what made it?

01:00:28NH4, CL.

01:00:29How easy are you?

01:00:31NH4, OH, PLUS, HCL.

01:00:34Same will be NH4, CL, PLUS, PANI.

01:00:38I will give you a question.

01:00:41I already had a mole, I had to give you a mole.

01:00:44Today I had a mole.

01:00:46First of all, I had to give you a mole.

01:00:48Because the molarity has no reaction.

01:00:50Hello?

01:00:51Who has to give you a mole?

01:00:53It will happen.

01:00:54It will happen.

01:00:55It will happen.

01:00:56But it will happen.

01:00:58No.

01:00:59No.

01:01:00Mole.

01:01:01No.

01:01:02Mole.

01:01:03Reaction.

01:01:04Next point.

01:01:05Mole.

01:01:06Mole.

01:01:07Mole.

01:01:08Mole.

01:01:10Mole.

01:01:18Mole.

01:01:23No.

01:01:24Mole.

01:01:25pluck.

01:01:26?"

01:01:27I will show you.

01:01:29Lol?

01:01:31Lol buradan is doctor.

01:01:33Anyway,

01:01:34I will show you.

01:01:37Ky Celsius.

01:01:382.

01:01:38We will also reveal two.

01:01:41How many millions to get in the middle?

01:01:44So,

01:01:45we have millions of millions of millions of millions of millions.

01:01:49So,

01:01:50will you start?

01:01:51Not yet.

01:01:52How much will it be?

01:01:53How much will it be?

01:01:54How much will it be?

01:01:55but we have zero to save it.

01:01:57You can't get it in the numerical

01:01:59but you don't have to get it.

01:02:01You can't get it.

01:02:03Now, you can tell me,

01:02:05how will it become?

01:02:07How will it become?

01:02:09How will it become?

01:02:11Now, tell me,

01:02:13the solution is who made it?

01:02:15Oh, you've been single.

01:02:17I felt like this mixture is

01:02:19but it's not the mixture.

01:02:21Now, which salt is?

01:02:23Weak, base, strong, acid.

01:02:27Rooko, Jara,

01:02:29क्या पानी में salt बन क्या आया है?

01:02:31क्या उसमें से एक वर्कर आयन है?

01:02:33कोहराम मचाए,

01:02:35पानी के तोड़के जाए,

01:02:37salt hydrolysis का concept लगाया,

01:02:39अरे, salt hydrolysis आ गया इसमें?

01:02:41Strong भी आ गया, weak भी आ गया, salt भी आ गया,

01:02:43अरे, हाँ या ना,

01:02:45उसका concept लगाऊंगा,

01:02:46सुरू हो जाओ,

01:02:47फिर समय देता हूँ आपको.

01:02:49अब salt कौन सा है,

01:02:58उसका pH का formula याद करो,

01:03:00solution acidic है, basic है, यह सोचो,

01:03:02और अगर solution, एक बच्चे न मुझे answer बोला,

01:03:05मैंने सायद answer सुनते ही मना कर दिया, क्यों?

01:03:08क्योंकि मुझे पता है, salt अगर acidic solution है,

01:03:11तो pH कभी साथ से जादा हो ही,

01:03:13समझ पाए बच्चे?

01:03:15बोलना नहीं है, रूल भूल गए आप?

01:03:29मैंने answer बोलने का इसलिए मना किया होता है,

01:03:31क्योंकि हमारे बच्चे ऐसे होते हैं,

01:03:32वो कहते हैं सरान सरां, बताओ तरीके हम बताते हैं,

01:03:35और अगर कभी मैं कह दूँ,

01:03:37हाँ answer 4.5 सभी सब का आ जाता है,

01:03:39कहीं से भी निकाल लेते हैं,

01:03:41उस तो उल्टा फुल्टा मल्टिप्लाई करके,

01:03:43आई जाता है,

01:03:45सर आ गया सर,

01:03:47इसलिए answer बोलने का नियम नहीं है,

01:03:49सीखो ना यार, जलतियां करिए, कोई दिकत नहीं,

01:03:51मगर सीखने का अपना मजा है, आईए,

01:03:53यहां तक पहुँच गए, रुको, रुको, रुको, अब बताओ, यह सॉल्ट है कि नहीं है,

01:03:57अब सॉल्ट कौन सा है,

01:03:59सबसे पहले सॉल्यूशन को पह है,

01:04:01पहचान लिया, अब कौन सा सॉल्ट है,

01:04:03स्ट्रॉंग आसिड वीग बेस,

01:04:05लगाओ कंसेप्ट,

01:04:07सबसे पहले सॉल्ट है,

01:04:09सुल्ट है,

01:04:11स्ट्रॉंशन का पहचा से कम साथ से जादा,

01:04:13पहच का फॉर्मला याद है,

01:04:15सेवन माइनस हाफ,

01:04:17पी के भी,

01:04:19माइनस,

01:04:21हाफ लॉक सी, बोलो ड़न,

01:04:23रुख जाओ, रिवाइस करते हैं,

01:04:25यह यह पी नहीं है, बी है,

01:04:27पी जैसी कोई चीज नहीं है, मारकर ने धोका दिया,

01:04:29आया न, चलिए,

01:04:31मुझे बताओ, सेवन माइनस हाफ,

01:04:33पी के भी, मैनस हाफ लॉक सी,

01:04:35क्या मुझे सेवन पता है,

01:04:37क्या मैं पी के भी निकाल लूँगा,

01:04:39समस्या कौन देगा,

01:04:41सी का मतलब कांसन,

01:04:43उस आयन का, जो पानी को तोड रहा है,

01:04:46बोलो, डन, अभी बताओ,

01:04:48क्या वो आयन यहां से आएगा,

01:04:50यह कंसंट्रेशन है कि मिली मौल,

01:04:52तो मुझे कंसंट्रेशन निकालना,

01:04:54सबसे बड़ा साप यहां पे,

01:04:56क्या कंसंट्रेशन निकाल लोगे,

01:04:58कंसंट्रेशन का फॉर्मला बोलो,

01:05:00कंसंट्रेशन का फॉर्मला लिख रहा है,

01:05:03कंसंट्रेशन निकाल रहे हैं,

01:05:07तो मौल में आपका लिख दूँ,

01:05:09किसका, कितने मौल हैं,

01:05:12दो, वॉल्यूम कितना,

01:05:14दस लिख दूँ,

01:05:15अरे वो सवाल दस वाला खतम हो गया,

01:05:17you can buy a 200 plus 200-400-10 liter-wool-are sir

01:05:23with the previous question yes or no?

01:05:27Tell me, what volume was 400 ml?

01:05:301 min.

01:05:31This mole is a million, this is a million.

01:05:33And the million is not a million.

01:05:36I will say that 1,200 will take 1 by 2 into 10 to power minus 2.

01:05:42I will say that 0.5 into power minus 2.

01:05:44to go together to have the minus three and then the minus three to enter the

01:05:48the consultation I am asked to put formula with the salt.

01:05:52Oh sorry this is the same thing.

01:05:55Yeah, yeah, pH is equal to seven minus half.

01:05:58PKB's nusvalidic.com

01:06:00Let's do that.

01:06:02You can do that.

01:06:03Yeah.

01:06:04Yeah.

01:06:05Yeah.

01:06:06Yeah.

01:08:09क्लियर है हर सवाल में काम एक ही कर रहे सबसे पहले solution को पह है

01:08:12reaction होती है तो reaction इसी तर्ज पर अगला सवाल लिख लिए पहले से

01:08:17हां कि आप बात करें बहुत टाइम है मैं समझा रहा हूं एक एक स्टेप इसलिए आप करेंगे तो

01:08:27आप आधे करेंगे फॉर्मला लगा लिया पी के भी हवा में कर लिया सी को सॉल क्या इतना तो नीठ डॉक्टर बनने वाले

01:08:34कितनी के Pizza कि यह भी नहीं कर सकते है हाह कर लिक हो जरा अगला सवाल है लिखो कि

01:10:32is like a don't know I said a different solution a different way a bit of a week

01:10:40or the other way so we can solve the name of the concept of a buffer or put it or

01:10:46put it up and then it's hard to put it up and then it's not a buffer yeah yeah

01:10:50now I'm a buffer if you can see the buffer concept I can see the answer

01:10:57the question does you do?

01:11:05Yes sir, some answer was given.

01:11:12There is 3.3.

01:11:14The answer is given.

01:11:20४ घचान गया कि solution कैसा है buffer � अब दूसरा क्या सवाल हमसे pH पूछा है तो formular pH का लगा लो,

01:11:37Now copy pH formula,

01:11:39formula,

01:11:40you can't write.

01:11:41pH is equal to pK,

01:11:43plus log concentration of conjugate iron upon weak acid.

01:11:49Now check.

01:11:51How many things are known?

01:11:52We don't know.

01:11:54Hello.

01:11:55How many things are known?

01:11:57And how many things are known?

01:11:58We don't know.

01:12:00So, the other thing,

01:12:01we don't know.

01:12:02How many of you can get KB?

01:12:04We don't know.

01:12:05That's so simple, right?

01:12:09So, I'll start with PKB.

01:12:12And PKB, how much will it be?

01:12:1310.

01:12:14Here, PK, how much will it be?

01:12:154.

01:12:16So, 14 minus 10, that is 4.

01:12:18Let's get 1.

01:12:19Now, all my work will be here.

01:12:21Tell me,

01:12:23conjugate iron and weak acid.

01:12:25Can I know the weak acid?

01:12:27Where are the efforts?

01:12:29Conjugate iron.

01:12:30Can I get here?

01:12:31Can I have Henderson equation salt?

01:12:34Nicho Jinko Jinko Henderson equation

01:12:36sna

01:13:04is 2 into 10 ki power minus 3, right?

01:13:06Sari values ko put karthay hain, solve karthay hain,

01:13:09to pk ka maan kitna aya? 4,

01:13:11aur yahaan liqtah hoon log,

01:13:132 into 10 ki power minus 3,

01:13:15aur weak acid kitna hai 10 ki power minus 2,

01:13:18kya aap isse solve karthay hain?

01:13:19Jab isse solve karthay hain,

01:13:21to aagla saap calculation me kiasse dhsega,

01:13:23suniye ga, 10 ki power minus 2 per gya,

01:13:25to 10 ki power 2,

01:13:26that comes out 2 into 10 ki power minus 1,

01:13:30rukho jara, kya aap b minus log ye laga dhu?

01:13:32Aap satark ho chukye hain,

01:13:34aapko pata hai,

01:13:34kahaan kahaan sawal galat hootay hain, right?

01:13:36Yeh aapke negative ko avoid karhe ga.

01:13:38Negative kyun hoota hai?

01:13:40Kaya bari ispere bhi dependent,

01:13:41aapne cheezo ko sikha kaise hai?

01:13:43Aagar bar bar un steps ko dhimang me rakhengue,

01:13:45jahaan galat hoota hai,

01:13:46aapki habit me hooga,

01:13:47to negative nahi hooga.

01:13:49Chalega?

01:13:49Aayya saab,

01:13:50isko solve karlo ge kya?

01:13:52To 2 into 10 ki power minus 1,

01:13:54mujhe proper log ka formula lagana padega.

01:13:56To log a plus log b, right?

01:14:0010 ki power minus 1,

01:14:01minus 1 log 2 ki value 0.3,

01:14:04to minus 1 0.3,

01:14:05minus 0.7,

01:14:07minus 0.7,

01:14:09to 4 minus 0.7 comes out 3.3.

01:14:12Is this clear?

01:14:14So the correct answer is 3.3.

01:14:16Sabhi bachche kar lhe.

01:14:17Step number 1,

01:14:18solution peh hai.

01:14:19Step number 2,

01:14:20PKB se PK nikaalou.

01:14:22Step number 3,

01:14:23C ki concentration.

01:14:24Step number 4,

01:14:25mtlap saap,

01:14:26log C mein galti.

01:14:28Chalega?

01:14:29Har step me sambhal ke chalenghe,

01:14:30toh antak sahih answer pehunchenghe.

01:14:32और ये इस profile के अच्छे सवालों में है,

01:14:35ये मस सोचना,

01:14:35ऐसा सवाल आए नहीं,

01:14:36मैंने J233 का,

01:14:38salt hydrolysis का,

01:14:38same profile के सवाल आपको कराया है.

01:14:40और J233 में लगभग लगभग जो paper अच्छा होता है,

01:14:43तो हमारी needs match कर जाता है.

01:14:45Hello?

01:14:46अगर समझ पाए हैं,

01:14:47तो क्या मैं अगला सवाल दे दू?

01:14:49एक बहतरीन सवाल.

01:14:51वो वाला दे दू क्या?

01:14:52लेखो फिर आज वो सवाल आपको दे देता हूँ.

01:14:55लिखिए.

01:14:55दूरिंग, दूरिंग, टाइट्रेशन, आधे तो इसी में परिशान, कठीन होगा कुछ.

01:15:05अच्छा, अब मैं यहां से दो बाते कहना चाह रहा हूँ.

01:15:08एक, यह सब्द क्या है?

01:15:10इस टॉपिक की निव भी रख रहा हूँ.

01:15:11और दूसरा इस सब्द से घबरानी क्या वश्रक्ता नहीं है.

01:15:14बहुत सिंपल से कहानी है.

01:15:16अभी तक जो आपने पढ़ा, वही पूरी कहानी टाइट्रेशन में समाही थे.

01:15:19कैसे? लिखिएगा.

01:15:20During titration of acetic acid, 40% of acetic acid is neutralized.

01:15:3840% of acetic acid is neutralized by sufficient amount of potassium hydroxide के हुए अच्छ.

01:16:00इसको थोड़ा फील कर लो.

01:16:03Potassium hydroxide के बारे में क्या बोला है?

01:16:06Sufficient amount.

01:16:07तो वो कम है कि जाड़ा है?

01:16:11Sufficient का मतलब क्या होता है?

01:16:13जाड़ा की कम?

01:16:15Sufficient का मतलब कम?

01:16:18बेड़ा, आपके कितने नमबर आ रहे?

01:16:20Sufficient मतलब 200 आ रहे.

01:16:21Sufficient का मतलब क्या? कम की जाड़ा?

01:16:24Sufficient का मतलब पर्याप्त.

01:16:26ना जादा ना कम.

01:16:28If it starts with one molar concentration of acetic acid,

01:16:57then calculate pH of solution.

01:17:04And in the bracket, we have the acetic acid that we have to do.

01:17:091.8 into 10-5.

01:17:17If you study this, you need to study this.

01:17:22When you give me a question in paper,

01:17:23then my motive will not be asked to make a question.

01:17:27So, when you ask a question,

01:17:29then try to make a question.

01:17:30Just a small concept of a concept,

01:17:32so that you will learn it.

01:17:33I am saying that you will get it,

01:17:35that you will not be able to study this paper,

01:17:37which you have to study,

01:17:39which the concept is strong,

01:17:40that you will make a question.

01:17:42Let's go.

01:17:44It will become an easy question.

01:17:47You have to make an illusion.

01:17:49You will make a concept.

01:17:50It will become an easy question.

01:17:54Step number one.

01:17:57How do you do those things up?

01:17:59What do you do?

01:17:59Acid base or no?

01:18:00Yes.

01:18:00-р motion ?

01:18:01Reaction or how do you turn will leave your reaction?

01:18:02Yes.

01:18:02بans感觉 it happens.

01:18:03Following the reaction,

01:18:04slightly more何?

01:18:05Acetic, acid and

01:18:06Acetic

01:18:07plus Élasesnivehá

01:18:09cooledasek ,

01:18:10strong base是啊,

01:18:11and this result will

01:18:13not be made a problem.

01:18:15Salt plus…

01:18:15Pants

01:18:16That will balance that.

01:18:17desire in reply is using

01:18:18so that if you keep adjusting,

01:18:19sometimes more intermediate than this error

01:18:19will not be needed to write…

01:18:24It willcíaishes up.

01:18:25Ambossate mr. relieving

01:18:29individually

01:18:31yeah

01:18:33yeah

01:18:36yeah

01:18:39yeah

01:18:42yeah

01:18:46yeah

01:18:53कि मैंने एने लिख दिया क्या के है सॉरी सॉरी मैंने पोटेशियम बोला था तो आज यहां पे हम सब

01:19:02के सामने आ चुका है सॉल्ट और साथ में वीक असर्ड सोलूशन का पता लगा यह कैसा सॉलूशन है

01:19:07तो क्या मैं फॉर्म्ला बफर का लगा लूँ एक वीक असर्ड है यहस उसका सॉल्ट है यहस और हम फॉर्मला लगाते हैं पी एच का राइट जब हम पी एच का फॉर्मला लगाते हैं तो पी एस इस्कॉल टू पी के

01:19:19plus log of

01:19:21concentration of conjugate iron

01:19:24upon weak acid

01:19:26eq bachcha کہta ha concentration of ci

01:19:28bhai kyun galat yaad kar rho

01:19:30pura conjugate iron bolne me kya

01:19:32dhikkat hai

01:19:32jab suru se galat yaad karthay hain

01:19:34to shawal bhi aapke galat hootte hain

01:19:36yaa ap nahi sache pa rhoen

01:19:38और yahe karaan hai bachcha bara bara bara pardtah hai

01:19:40ek bar tabiat se pardlo na yaar

01:19:41ab batao ye ci boloo ga conjugate iron

01:19:45conjugate

01:19:45or niache kya likhar hai haom

01:19:47weak acid

01:19:49what should be the PK

01:19:59four point

01:20:00solve

01:20:01I mean

01:20:01I don't think

01:20:02I don't think

01:20:03I don't think

01:20:04I don't think

01:20:17sir

01:20:17पहली बार तो आपने concentration बोल दिया है, और नहीं बोला होता, तो भी buffer में mole भी चलेगा, millimole भी चलेगा, gram equivalent भी चलेगा, milligram equivalent भी चलेगा, acid में और base में सोचना है concentration होना चाहिए, यहाँ buffer में कोई दिक्कत नहीं है, तो link देता हूं में, conjugate time कितना है, 0.4, और यह कितना है, 0.6, च

01:20:47होच गये थे, आतों कि answer कि यार, हाया ना, बढ़िया, तो pH is equal to 4.74, प्लस, log 2 by 3, तो log 2 minus log 3, log 2 की value, log 2 की value, 0.3, log 3 की value, 0.48, चलेगा, इसको solve लिए आंसर 4 पॉइं, the correct answer, is clear, पक्का, कहानी आगे बढ़ाऊं, अभी तक हमने क्या क्या सीखा, सब को clear है,

01:21:17और भी सवाल कर सकते हैं, लेकिन जितने सवाल किये हैं, सब में concept एक ही था, सबसे पहले solution को पह है, और जो मैंने आज हुंबग दिया, आप से request करूँ, अप लीज उसे करिएगा, ठीक है, प्यारे बच्चों, अभी तक ionic का एक बहुत बढ़ा हिस्सा खतम हुआ, अब यह

01:21:47हैं कुछ जिन में सब लोग पढ़ाएंगे, चलेगा, जो titration topic है, वो है क्या, that is the part of practical chemistry, that is the part of, तो ऐसा समझ लो, कि मैं ionic तो पढ़ा ही रहा हूं, लेकिन जो practical chemistry का हिस्सा है, वो भी यहीं add कर रहा हूं, तो आप अलग से यह मत सोचना, कि उसकी अलग से class होगी, चलेगा,

01:22:17एक-एक सवाल लगाईए, 600 सवाल का target मेरा नहीं आपका होना चाहिए, अच्छा, इनका इनको करने दो, आपको करना है, चलेगा, दूसरा, paper में बढ़िहां सवाल मिलेंगे, समल करना, negative मत कराना, और discussion कल online, offline, दोनों रहेगा, that's all for today, thank you so much, offline doubt में रहेंगे, online discussion रहेगा, चल
