00:00:00इस अब चयां पूप कर अगर कभी स्कूल जाते थे तो कभी कभी केमेस्ट्री की लेबरेट्री की गलियों में आना जाना होता था

00:00:23। और जब उन गलियों में आना जाना होता था तो कभी-कभी आपने देखा होगा

00:00:29chemistry के laboratory में ऐसे कुछ उपर से गिराते रहते थे wound वो और वो सारा का सारा

00:00:35जो कारिकरम था actually उसी को कहते है titration तो मन में सबसे पहला सवाल

00:00:40titration है क्या दूसरा सवाल इसे कैसे करते हैं इसके पीछे concept क्या है logic क्या है उन पर बाते करते हैं

00:00:46सबसे पहला सवाल आपके titration है क्या और करते क्यों है

00:00:49imagine करते हैं आज मेरे सामने वहाँ पर एक लिटर की bottle है और यह जो एक लिटर की bottle है

00:00:56we got 1 mole of solute. How much? If we got 1 mole of solute,

00:01:02then tell us how much? 1 mole of solute. 1 liter of water is 1 mole of solute,

00:01:07then the molarity is 1 mole of solute. But the twist is not a twist.

00:01:12I have 1 liter of water in your face, and I have something to do with it,

00:01:17and I didn't tell you how much. I didn't tell you how much.

00:01:21I tell you, tell us what the molarity is.

00:01:25Now, you can't tell us, because you don't know how much you get.

00:01:30So, I'll tell you, this is a solution, which the concentration has no one?

00:01:34This will be the solution of unknown concentration, right?

00:01:37This will be the solution of unknown concentration, right?

00:01:38If we know a solution, which the concentration has no one,

00:01:43this whole methodology, we will tell you.

00:01:46Titration. Titration is a method, a method, a way, a way,

00:01:50which we can tell you, which we can tell you,

00:01:52which the concentration of unknown solution is what the concentration is.

00:01:55Now, you can tell us, you can tell us,

00:01:57how much you can tell us, what the logic is.

00:01:58What the logic is?

00:01:59How much you can tell us?

00:02:00We can tell you, this is a method.

00:02:01Experimental method.

00:02:02Experimental method.

00:02:04To calculate.

00:02:06Experimental method.

00:02:08To calculate.

00:02:09Concentration of unknown solution.

00:02:12Okay, one minute.

00:02:13Last class has nothing,

00:02:14I will tell you,

00:02:15but a little bit about it.

00:02:17Concentration of unknown solution.

00:02:19Okay.

00:02:20The past topic,

00:02:21before you with the syllabus,

00:02:22I want to understand this.

00:02:23In the last year,

00:02:26there will be a new topic added,

00:02:27which has been called practical chemistry.

00:02:28What do you want to inspire?

00:02:29When the practical chemistry check,

00:02:31I want to show you?

00:02:33If there is not any topic of practical chemistry,

00:02:35and what I want to tell you,

00:02:37I want to tell you,

00:02:38If there is no problem, then I will tell you a new topic, which is called Practical Chemistry.

00:02:44In Practical Chemistry, there is a simple answer.

00:02:47You can see the practical manual from NCRT, which is the practical manual,

00:02:52which is written in our syllabus.

00:02:55Our NEET, which NTA has given us, what do we say?

00:02:59When we talk about Practical Chemistry,

00:03:02the first topic that we cover is titration.

00:03:05And then, when we talk about Titration,

00:03:10when we talk about Titration,

00:03:13there are two types of titration in your syllabus.

00:03:17One is acid-based, and one is redox.

00:03:20This is very good to clear that acid-based titration in your syllabus,

00:03:25and redox titration in your syllabus.

00:03:28What I will tell you about everything.

00:03:30I will tell you about the syllabus.

00:03:32The syllabus has been added.

00:03:33With this, we have some of the examples.

00:03:35In the thermo code, we have to add some of the details.

00:03:37In the the enthalpy of solutions,

00:03:39we have already taught us.

00:03:41This has also covered the chapter in the same chapter.

00:03:44After that, there is a small topic.

00:03:46There is an additional topic called Collides.

00:03:48In the collides, we have to talk about preparation methods.

00:03:51So I want to say that your syllabus practical chemistry added 5-6 topics, and those 5-6 topics, how to cover them?

00:04:00The first one is titration, I cover ionic, I'm saying. If I don't study here, then there is no difference.

00:04:07But we will finish this whole story from practical chemistry.

00:04:10Redox titration, when I do redox, the concept of gram equivalent, I tell you all the numericals.

00:04:16Redox titration, what is covered in redox titration?

00:04:18Kemeno 4 vs. oxalic acid, Kemeno 4 vs. oxalic acid,

00:04:23and then another topic is Kemeno 4 vs. more salt.

00:04:27Children, the reaction is right?

00:04:29They are inorganic chemistry in detail,

00:04:32but the numericals, the concept of gram equivalent,

00:04:36we have already redoxed redoxed.

00:04:39And you can see gram equivalent of gram equivalent.

00:04:41Where gram equivalent of A, B, B, C, D.

00:04:44Listen, numericals are already that,

00:04:47which you have already covered in redox.

00:04:49Just the reactions to IOC,

00:04:51we will tell you.

00:04:52Pulling out that I cover this, Ionic.

00:04:54This numericals is covered in redox.

00:04:57Redox is covered in IOC.

00:04:59The reaction is covered in the IOC.

00:05:00The thermo already covered in chapter.

00:05:02Indicator titration will be now.

00:05:04Then the colloids will be a small section,

00:05:07which you will need to do with practical chemistry.

00:05:10Don't assume that any practical class will be in practical chemistry.

00:05:13Did I say clear?

00:05:15Don't think that practical chemistry will be in practical chemistry.

00:05:18I will fit everything in the chapter.

00:05:20I will fit everything in the chapter.

00:05:22There will be a small topic which will be called colloids.

00:05:26Then we will see the last one.

00:05:28What will I say to you today?

00:05:30Titration.

00:05:31So first think about practical chemistry.

00:05:33If you have a practical chemistry,

00:05:34then you will need to be in practical chemistry.

00:05:37What are we trying to calculate?

00:05:39Consent of unknown.

00:05:41This is the answer to you.

00:05:43I have a solution that we don't know.

00:05:45We don't know the concentration of that.

00:05:48We want to know the concentration of that.

00:05:50And the concentration of that method is called titration.

00:05:55Let's imagine.

00:05:58I have a glass.

00:05:59You can see a glass.

00:06:00You can see a glass.

00:06:01This one was given an solution.

00:06:03Here what is called solution.

00:06:04What is the solution?

00:06:05This one is a concentration.

00:06:06What is the solution?

00:06:07It won't be known.

00:06:08What is the concentration?

00:06:10We don't know the concentration.

00:06:12I will say unknown concentration.

00:06:13That is in the world of chemistry.

00:06:14What is the analysis?

00:06:15How is the analysis?

00:06:16What is the analysis we're doing?

00:06:18What is the analysis?

00:06:19We've just said analyze.

00:06:21What is the analysis?

00:06:22What is the analysis?

00:06:23Here in other terms of technical terms?

00:06:25It will beotto.

00:06:26Tight trend.

00:06:27Tight trend.

00:06:28Okay, now listen to this solution, this is the concentration we know, or not?

00:06:33So, when we know the unknown solution we know the concentration we know,

00:06:38then we know a solution which is the concentration we know.

00:06:43So, the second point, to calculate the unknown concentration,

00:06:49to calculate the unknown concentration, we have to use,

00:06:55a solution of known concentration.

00:07:12We have to use a solution of known concentration.

00:07:16can use the foundation of which the concentration we know.

00:07:21We build a foundation of the emphasize which is above our solution.

00:07:24We build a concentration of which the concentration we know.

00:07:30And only we have to create the foundation of which we know as that,

00:07:34as we call the tiefing trend, what do we call it?

00:07:36Tightrend.

00:07:37We do.

00:07:39Tightrend.

00:07:40With the help of tightrend, with the help of?

00:07:46Okay, so what we are doing is calculation of concentration of unknown solution with the help of some known solution.

00:08:08Okay, so what we are doing is calculation of concentration of unknown solution.

00:08:20Both solutions must be of opposite nature.

00:08:29When we have titration, the two solutions must be of opposite nature.

00:08:36This means that if we have acid and acid, we must be of base.

00:08:42If we have oxidant, we must be of reductant.

00:08:46If we have oxidant and acid, we must be of oxidant.

00:08:50If we have oxidant and acid and base, we call acid-based titration.

00:08:57What do we say?

00:08:58If we have oxidant and oxidant, we call it redox titration.

00:09:03If we have oxidant and oxidant, we call it redox titration.

00:09:07What do we say?

00:09:08What do we know?

00:09:09Concentration.

00:09:10If the other solutions are opposite, just like we can be chosen from the Americas,

00:09:38the next point is type of titration. Next point is type of titration. So,

00:09:45dear children, first of all, we are studying. We are studying titration, and we are studying

00:09:53acid-base titration, which is our syllabus, that is redox titration. But today's class

00:10:01in this class, my discussion is going to be where to go, which is the acid-base titration?

00:10:08Okay, now you will do titration. What will you do to know the unknown solution?

00:10:16What is the concept of the logic and the concept of this concept? We don't know

00:10:22or we don't know. And we don't know. Okay, here is the solution.

00:10:27We don't know the same nature. Okay, if both are opposite, then we will be

00:10:32going to be reaction or not? If we don't know the base, then we will be reaction.

00:10:36Okay, when will it be reaction? It will be reaction when it will be,

00:10:40until the acid will be neutral, until the acid will be neutral.

00:10:44Meaning, until the reaction will be complete, until the reaction will be

00:10:48going to be agree or not. When we do titration, what do we do?

00:10:53So titration, we will take two opposite solutions to the opposite solution.

00:10:58We will take the opposite solution, when we do reaction complete.

00:11:00Then we will take the next point. Titration is performed.

00:11:04Titration is performed until reaction is complete.

00:11:09Titration, we will perform until the reaction will be complete.

00:11:12We will complete. We will remember one more time.

00:11:14We will do the same thing.

00:11:22Write the reaction.

00:11:27See what we do?

00:11:29એક નીય ભ ભાસ એઓ હણ્તતાર્યે પારાંતપ્તલે પીર હીસે હારંતરયે દેંતર સેહેવે

00:11:35when the reaction is complete.

00:11:59complete.

00:12:01Next point, end point.

00:12:03End point.

00:12:05One word is end point,

00:12:07and one word is equivalence point.

00:12:11One word is end point,

00:12:13and one word is equivalence point.

00:12:15Let me tell you,

00:12:17end point and equivalence point

00:12:19are today for us

00:12:21one way, but

00:12:23two are a little.

00:12:25What is the end point?

00:12:27Equivalence point is equal.

00:12:29It will be.

00:12:31When you were in school,

00:12:33and if some child has experienced it,

00:12:35if it was said in school,

00:12:37it was said in school,

00:12:39it was said in neutral point.

00:12:41Does anyone have experimented in school?

00:12:45If you were said in school,

00:12:47then it is said in school,

00:12:49the same word is called neutral point.

00:12:51Point number one.

00:12:53End point is different.

00:12:55Equalence point is different.

00:12:56Equivalence point.

00:12:58For a particular situation,

00:13:00these three are the same.

00:13:02Now, what do we say?

00:13:04We perform the opposite nature

00:13:06of the solution?

00:18:00the

00:18:01In the next few minutes, we will be able to make sure that if the world has any titration in my face, I will tell you how the end point can we tell you.

00:18:08It's the theory, it's the concept, it's the theory.

00:18:09Let's go, kids.

00:18:11If you tell me the end point, what do you tell me?

00:18:14So, I have to understand that I need something that I want to know, that reaction is complete.

00:18:19Number one, the solution is to tell you.

00:18:22What can you tell me?

00:18:24What can you tell me?

00:18:26That's the other way.

00:18:27It's a blast.

00:18:29If the reaction was complete, everything would be full.

00:18:32If it's a good thing, it would be good.

00:18:35If it's good, it would be good.

00:18:37We said, this is good.

00:18:39Another way, let's take a look.

00:18:41When it's done, when it's done, it will be a titration.

00:18:44First, it's warm.

00:18:46Let's take a little bit of an arbonne.

00:18:47Sir, I've been doing an arbonne.

00:18:49Acid base.

00:18:51You can't hit the hands.

00:18:53Yes or no.

00:18:54That's what I want to say.

00:18:55I want to tell you, all the sense organs are, all the sense organs are used to be able to tell you that the end point is not.

00:19:03And believe me, every sense organ is related to a substance.

00:19:07But today, we will use a substance in our syllabus, which will tell you the end point, without any smell, without any sound, just by changing its color.

00:19:17Just by changing its color.

00:19:18And this is a substance.

00:19:20Indicator.

00:19:21Indicator.

00:19:22Indicator.

00:19:23What is it?

00:19:24Indicator.

00:19:25I'm going to teach you how to use titration.

00:19:26How to use titration?

00:19:27How to use titration?

00:19:28If we have hypothetical questions, what do we do?

00:19:30What do we do?

00:19:31Confirm.

00:19:32Next point.

00:19:33Diagram.

00:19:34Diagram.

00:19:35Diagram.

00:19:36particle.

00:19:37Give me a Doc.

00:19:39What is it?

00:19:39Little of course.

00:19:40Something, did you take a step toward the picture?

00:19:40Just, literally.

00:19:41I am making a работать.

00:19:43Yeah.

00:19:45We, we Soci préc岩.

00:19:45Notice there are 500 foot cubes and pictures.

00:19:47Like, every question, the first one is asking, is this person transformation, the last quarter?

00:19:49The first thing that you've been able to mention, is when you know about 1T, the last four square feet.

00:19:53Yes, even because then this also follows from the Crafts.

00:19:56Ha hap Hap?

00:19:57theory. So what we are doing, that is titration, let us write N1, V1 and N2. Yes, you can

00:20:05make a designer, no matter what you can make. Your own laboratory, your own design. I

00:20:10see that children have a bottle bottle. All of this is no problem at all. This is a

00:20:16school. It's not a laboratory, it's a designer. Do you get it? I don't know. I write the next point to find

00:20:26end point. So, dear children, now our concept, our concept, now we have to use the end point.

00:20:36Right? We have made four lines in the world. We have to make it so far.

00:20:40Yes or no? Yes or no? Strong acid, strong base, weak acid, weak base, weak base,

00:21:09in the world. What do you think? So, there are two situations. One is a dog and one is a dog.

00:21:14So, when the dog is a dog, when the dog is a dog, the dog is a dog, the dog is a dog.

00:21:18So, the dog is a dog, the dog is a dog. We have to identify when the dog is not at home. Yes or no?

00:21:33No. Oh, no. You are the dog. Who calls it? Yes or no? No? Yes or no. We have to

00:21:43identify when the dog is not at home. The human animal, the dog is not at home. So,

00:21:46Now, the question is, the end point is how to identify, right?

00:21:54So, the end point is how to identify,

00:22:01how to identify, how to identify,

00:22:06which means indicator.

00:22:09So, the next point is,

00:22:13to identify, end point,

00:22:18to identify, end point,

00:22:21we have to use a substance known as indicator.

00:22:24So, we have to use a substance known as indicator.

00:22:25So, we have to use a substance called indicator,

00:22:28which is what is called indicator.

00:22:31Indicator, where is the word?

00:22:33Indicator.

00:22:35What does it mean?

00:22:37What does it mean?

00:22:39Which point?

00:22:41Indicator.

00:22:42These are organic substances,

00:22:47these are organic substances,

00:22:51which indicate end point,

00:22:55which indicate end point,

00:22:59by color change.

00:23:02Now, some years ago,

00:23:04there is a question came.

00:23:05The question was,

00:23:07what is the question?

00:23:08Is the question?

00:23:09Is the question?

00:23:11Is the question?

00:23:12Is the question?

00:23:13what is the question?

00:23:14Do I understand?

00:23:15What do you think?

00:23:16The question?

00:23:17Yes.

00:23:18I have to ask my question.

00:23:19Can you,

00:23:20look at the question?

00:23:21Is the question?

00:23:23How can you turn on that?

00:23:24However, however, indicator indicates end point, by using any of our sense organs.

00:23:50But if you have any of our sense organs, you can use any of our sense organs.

00:23:59But in the 12th level or school level, what are the indicators?

00:24:07What did you say?

00:24:08Now, some years ago, a scientist named Oostwald.

00:24:11What was the name?

00:24:12Oostwald.

00:24:13What was the name?

00:24:14Oostwald.

00:25:05Oostwald.

00:25:06Oostwald.

00:25:07Oostwald.

00:25:08Oostwald.

00:25:09acid are weak organic or base.

00:25:12Say, it's going to go.

00:25:14In the same way,

00:25:15it's going to be acid or it's going to be weak.

00:25:20If it's weak,

00:25:22then the equilibrium is in life.

00:25:23Everything is in the same way.

00:25:25Say, it's going to be a concept.

00:25:27Listen to this.

00:25:29I'm telling you, what the world is.

00:25:31What do you mean?

00:25:32Every weak substance,

00:25:34every weak acid,

00:25:35every weak base,

00:25:36is the ones that you can see,

00:25:39the only number of properties,

00:25:41or the other ones,

00:25:42form-a-like,

00:25:44or some kind of smell,

00:25:45in fact.

00:25:46But if it's this one,

00:25:48then you can create an indicator.

00:25:49So write,

00:25:52what can change its color?

00:25:54What can change its color?

00:25:57What can change its color?

00:26:00Now, we tell them what we have to learn.

00:26:02What are we doing today?

00:26:03We are going to know.

00:26:05हम क्या पता करते हैं सब्दों को बոलिए साइद यह WhatsApp पहली बार सुनरे हऊँ प्लीज repeat

00:26:10करिएगा हम क्या पढ़ रहें उसमें क्या पता करतें कोन संटरेशन किसका पता करते हैं यही सवाल आते

00:26:18what is analyte?

00:26:19And there is a paper that I have shared,

00:26:22so that's why analyte is studied,

00:26:24right?

00:26:25It's an analyte.

00:26:26Analyte, which we can analyze,

00:26:28titrate, which we can often use.

00:26:30Ultimately, we know how we know it is.

00:26:32D women's grammar,

00:26:34what about the end point?

00:26:36Indicator,

00:26:38we know it is.

00:26:40We know the woman we know after the end point.

00:26:44Even if we know it,

00:26:46the end point is coming.

00:26:48Now, how do we know how to take a picture?

00:26:50Here we have the indicator,

00:26:52here we have two concepts.

00:26:54You have two indicators established in society.

00:26:56Here you have two indicators,

00:26:58What I've said here is acidic.

00:27:00And here you have to tell me,

00:27:02What I've said,

00:27:02The population is what you have learned?

00:27:05It's acidic indicator.

00:27:06You can see it.

00:27:08It's acidic indicator.

00:27:11It's acidic indicator.

00:27:12It's basic indicator.

00:27:14छलेगा, एक होगा, acidic indicator एक होगा, basic indicator रुको जड़ा यह acid है कि weak acid, तो जब हम acid लिखते थे, क्या है लिखते थे? अभी कोई normal acid, यह indie, तो हम इसे लिख देंगे h-i-n, बोलो चलेगा, तो acidic indicator का paper presentation हो जाएगा h-i-n, और basic indicator का paper presentation हो जाएगा inиться अ-o-h,

00:27:43Hello!

00:27:44Acidic Indicator, what is the solution in the solution?

00:27:48Basic Indicator.

00:27:50Bolo done.

00:27:51Concepts, what is the indicator?

00:27:53What is the indicator?

00:27:54Is it an acid or a weak acid?

00:27:57When you go to the water,

00:27:59the equilibrium,

00:28:00when you go to the water,

00:28:02when you go to the concept,

00:28:04when you go to the real indicator,

00:28:06we go to the basic indicator.

00:28:08We go to the methyl orange.

00:28:10Methyl orange.

00:28:12How does the paper presentation mean?

00:28:15I mean, first of all,

00:28:17what is the methyl orange?

00:28:19What is the answer?

00:28:20What is the answer?

00:28:21We go to the basic acid.

00:28:23We go to the OH,

00:28:24then we say that.

00:28:26What do we say?

00:28:27We go to the basic indicator.

00:28:30We go.

00:28:31We don't have to write.

00:28:35One is the basic indicator,

00:28:38which is the methyl orange.

00:28:40So,

00:28:41we have to write.

00:28:42One is the acidic indicator,

00:28:43which is called Phenophthalene.

00:28:44Right?

00:28:45Which is called Phenophthalene.

00:28:46And Phenophthalene.

00:28:47We have to write here a paper presentation.

00:28:50HPH.

00:28:51What do we say?

00:28:52So,

00:28:53here are two words.

00:28:54One is my own.

00:28:55One is my own.

00:28:56One is my own.

00:28:57Yes.

00:28:58One is my own.

00:28:59One is my own.

00:29:00One is my own.

00:29:01Yes.

00:29:02One is my own.

00:29:03Yes.

00:29:04One is my own.

00:29:05Yes.

00:29:06Yes.

00:29:07One is my own.

00:29:08One is my own.

00:29:09One is my own.

00:29:10One is my own.

00:29:11One is my own.

00:29:12Yes.

00:29:13One is my own.

00:29:14One is my own.

00:29:15One is my own.

00:36:06I will tell you that the color will be pink. How is it? Is it good? Now I will get acid. What do I get? What do I get? I will get titration.

00:36:18So titration is how do I get titration? It will get some stopper. It will get this. You will get it. You will get it.

00:36:27You will get it. You will get it. You will get it. Now you will get it. Acid-based reaction.

00:36:36Now the solution is basic. How do you get it? Acid-based reaction.

00:36:43Acid-based reaction. When will reaction?

00:36:50I will get it.

00:38:09to have color change.

00:38:11I am not going to do opposite, but I am not going to do it.

00:38:16How many indicators are going?

00:38:17Let's explain it.

00:38:19First, I will listen to the acidic indicators.

00:38:22I will listen to the acidic indicators.

00:38:25What do you think?

00:38:28I will try to apply a different setting.

00:38:30If you want to, I will explain all the concepts.

00:38:33So I will explain it, then.

00:38:34Okay, I will explain it.

00:38:36I will tell you.

00:38:37Ascid indicator.

00:38:39As per Ostwald, in undissociated form, there will be light color and dissociated form.

00:39:06Dissociated form, there will be dark color, next point, acidic indicator, used in, basic medium, basic medium,

00:39:30and the other one will be, the other one will be, the other one will be.

00:45:52hai paur ye mere paas solution hai iska ph in 9.4 kitna hai toh betao fenophtilin ko use

00:45:58is beneficial or not?

00:46:00He will give the right result or not?

00:46:02Yes, this is true.

00:46:04If medium is acidic,

00:46:07if it is acidic indicator,

00:46:09then use is basic.

00:46:10If indicator is basic,

00:46:12then use is basic.

00:46:14If there is a problem,

00:46:16if there is a problem,

00:46:18then use will be used.

00:46:20Do you understand?

00:46:21I said before,

00:46:22which will be used,

00:46:23then where will be used,

00:46:24then where will be used,

00:46:25there will be a problem.

00:46:27Now listen,

00:46:28took a question

00:46:29What's this problem?

00:46:30I do the same problem.

00:46:31Do you have to,

00:46:32I didn't say,

00:46:33how many are the same ones?

00:46:34Each's equal,

00:46:35not only two have.

00:46:36What's this difference is?

00:46:37It's larger than 1000 moles.

00:46:40Because the our weasMauge

00:46:54between the same,

00:46:55in the other color, it will be easy to use, when we use the indicator, we try to do this

00:47:02that the concentration is not the same, but we will try to do this too, that we will

00:47:08not be able to do this, that we will not be able to do this.

00:47:11Do you understand?

00:47:13We will not be able to go so far.

00:47:15So, we have an experimental rule.

00:47:17This is one is to ten, or ten is to one.

00:47:20This is the same ratio here, which is the allowable range is 10.

00:47:30This is the 10.

00:47:33This is the 10.

00:47:35Here, we will be able to see the result of the result.

00:47:38This is the same ratio, which means the pH range.

00:47:42What am I able to see?

00:47:45which can tell you what I can say by the way I get it to be a picture range is pkin plus minus one

00:47:53Sum of three percent of pkin get it to get it to tell you that I feel that I'm going to

00:48:00tell you can tell me because I think that I do like it because you know it is a big indicator

00:48:07is basic photo they can't get it's like I'm at love so it's a small basic media maker

00:48:14is that it's okay to be sick now it's copy can get it I am so it's the usable range

00:48:20of 8.4 say 10.4 8.4 say yeah you can't get it Bologna 8.4 say it may he

00:48:32प्रिम्ट इस्तेमाल होगा उसमें भी अगर पी एच 9.4 हो गया तो सही रिज़र्ड मिलने वाला अब इस

00:48:40कंसेट को अगर समझ गये तो मुझे बस इतना बताना है कि दुनिया में जितने भी इंडिकेटर है सबके पी एच रेंज पी एच रेंज पी एच रेंज का मतलब समझो जैसे फिनॉप्ट पीएच रेंज कितनी आई 8.4 से अरे बोलो यार मतलब यह समझते हैं यह चोर के चोर

00:49:10यहां तक कंसेट था अब मुझे आपको कुछ फैक्ट याद कराने हैं तो कंसेट यह था मेरे प्यारे बच्चों कि अगर कोई इंडिकेटर है तो उसका अपना पी एच होगा और वो पी एच जो कि पी कि एच से रिलेट होगा हर इंडिकेटर का अपना पी एच रेंज हो�

00:49:40तो पी एच रेंज पी कि आई एन प्लस माइनस वन लिख लिया

00:49:53अभी तक कितनी कहानी हुई क्या सबको याद है मन में रिपीट करते रहे ना हम क्या यूज कर रहे हैं टाइडरेशन

00:50:07क्या पता करना है concentration हमें पता करना पड़ेगा and point love

00:50:36hr indicator hr indicator apne ph range me hr indicator apne ph range me h use kiya jaa

00:50:50saktata hai.

00:50:53hr indicator apne ph range me h use kiya jaa saktata hai.

00:51:01yad rhega.

00:51:02और थोड़ी सी चर्चा कर ले mhyahon ki और फिर पढ़ते हैं.

00:51:06हम सब के सामने लिखा अगला indicator इसका क्या नाम है Mithail?

00:51:09बोलो बेटा.

00:51:10अच्छा जब यह undissociated form में है, तो हलका रंग की गाढ़ा रंग?

00:51:14we are hypothetical for us today and I will be an indicator and will be under social for me

00:51:19concert and go back to push me simple because I'm a harkar and and associated form a garden

00:51:25dissociative form below get to know he so abhi philhar is that a certain area yellow and

00:51:30this is a certain area or you know it's a problem with you as a city can get a basic

00:51:35so it's not a basic medium at a gas day like the first point will be used in a city medium

00:51:42will be used in acidic medium.

00:51:46We will use this in the acidic medium.

00:51:50Okay, I have a question.

00:51:52If I have a question, if I have a medium, acidic, how do I have?

00:51:55So, tell me, which will dominate you?

00:51:59Which will dominate you?

00:52:00Acidic medium, I will not, H plus will you.

00:52:02I will not, I will not, I will not, I will not.

00:52:05There will be a question, where will I have?

00:52:07Logic will be used in acidic medium.

00:52:08So, if I have a solution acidic,

00:52:10then when you get it,

00:52:12then you will get more than OH,

00:52:13then you will get more than OH.

00:52:14Which will be called?

00:52:16Common iron or other iron?

00:52:18If you have a second iron,

00:52:20then you will get more than OH and H plus.

00:52:22So, OH and H plus will be reaction.

00:52:24Then you will get more than OH.

00:52:26Then you will get more than OH.

00:52:28So, in acidic medium,

00:52:30ME plus concentration,

00:52:32MEoh to more than OH.

00:52:34In the same way.

00:52:36Basic medium,

00:52:38in the same way.

00:52:40Basic medium में,

00:52:42MEOH की concentration,

00:52:44ME plus से ज्यादा.

00:52:46एक सवाल मेरा आप सबसे है.

00:52:48अगर कभी MEOH की

00:52:50कंसेंटेशन,

00:52:51ME plus के बराबर हो,

00:52:52तो बताओ,

00:52:53यूज करना आसान होगा

00:52:54कि नहीं होगा?

00:52:55और इससे हम बोलते हैं,

00:52:56no working condition.

00:52:58चलेगा?

00:53:00No working condition.

00:53:03अगर आप थोड़ा सा भी

00:53:05logic और common sense को समझते हैं,

00:53:07तो मुझे बताओ,

00:53:08हमने वहाँ पे formula,

00:53:09PH का निकाला था.

00:53:10तो यहाँ पे formula,

00:53:12PH का है कि POH का?

00:53:13आसान है.

00:53:14क्या आप बना लोगे formula?

00:53:16कोशिस करो, कैसे बनाओगे?

00:53:19POH बराबर.

00:53:22एक मिनट.

00:53:23PKIN बोला था.

00:53:24अब होता क्या है?

00:53:26acid के लिए के बोलते हैं?

00:53:27base के लिए?

00:53:28लेकिन indicator के लिए

00:53:30चाहे acid हो, चाहे basic.

00:53:31सब के लिए एक ही सब्स्तमाल करेंगे

00:53:33PKIN.

00:53:34यह एक rule है, चलेगा?

00:53:35तो मैं कह दूँ,

00:53:46ऐसा सवाल तो कभी आया नहीं है,

00:53:47लेकिन अगर आजाए,

00:53:48आपसे किसी भी indicator का pH या POH पूछे,

00:53:50तो formula आपके सामने है.

00:53:52चलेगा?

00:53:53एक बात बता दो जरा.

00:53:54चलते चलते.

00:53:55क्या POH,

00:53:56जब PKIN के बराबर होगा?

00:53:58क्या बोला सरने?

00:53:59जब PKIN के?

00:54:01इसको feel कर पाए गया.

00:54:03यह बराबर कभ होगा जब यह?

00:54:05यह पका?

00:54:08यह पूरा 0 होगा,

00:54:10तम न बराबर होगा?

00:54:11यह पूरा 0 कभ होगा?

00:54:13जब यह 1 होगा,

00:54:15मतलब दोनों equal होगा.

00:54:16एक सवाल पूछता हूँ,

00:54:17अगर कभी POH,

00:54:19PKIN के बराबर है,

00:54:20यह वर्किंग कंडिशन होनी चाहिए कि

00:54:22नो वर्किंग.

00:54:23लेकलो next point,

00:54:24if POH is equal to PKIN,

00:54:27तो इसे हम कहेंगे

00:54:29no working condition.

00:54:31आसान है बच्चों?

00:54:33अरे आसान है कि नहीं है?

00:54:35क्या इसका भी अपना POH range होगा?

00:54:37क्या होगा?

00:54:38बोलो,

00:54:39PKIN plus minus 1.

00:54:40बच्चों,

00:54:41अभी तक आपके निमान में क्या क्या से हो गया?

00:54:43कितने प्रकार की इंडिकेटर?

00:54:45पहले याद करेंगे फिर आगे बढ़ेंगे.

00:54:47यहाँ पर theory खत्म है न?

00:54:49कितने प्रकार की इंडिकेटर?

00:54:512.

00:54:52Number one.

00:54:53Number two.

00:54:54Acidic का इस्तमाल?

00:54:55Basic का इस्तमाल?

00:54:57Logic समझ गये?

00:54:58Reasoning आनी चाहिए.

00:54:59Reasoning के सवाल आते है, right?

00:55:01ऐसा क्यों?

00:55:02ताकि हम light से dark color का transformation समझ पाएं.

00:55:05ऐसा कोई किताबी नियम नहीं है.

00:55:07यह practical नियम है.

00:55:08Acidic को इस्तमाल करो basic में.

00:55:10Basic को इस्तमाल करो.

00:55:11ताकि light color से dark color में अंतर समझ में आए.

00:55:14नहीं तो dark से light में अंतर समझ में आने वाला?

00:55:16सवाल पूँच सकता है कि कैसा indicator है?

00:55:19जिसका unionized form, unionized form में उल्टा combination.

00:55:21ठीक है, वो यूज कर लो उल्टा.

00:55:23हलो, हमारे पूरे सरेबस में.

00:55:26क्या बोला मैंने?

00:55:27टोटल चार indicator की चर्चा होने वाली है.

00:55:30सबसे पहला indicator जो है, वो है methyl orange क्या है?

00:55:33आज़ो ज़रा, नाम में ही पहचान चुपी है.

00:55:36नाम में ही?

00:55:38मुझे बताओ, अब लिखना नहीं है.

00:55:40मिथाईल orange acidic indicator है कि basic?

00:55:42नहीं सुनाई दिया.

00:55:44तो बताओ, basic media में कैसा रंग दिखाएगा?

00:55:47ऐसा नहीं, नाम में ही पहचान चुपी है.

00:55:49नाम में ही?

00:55:51पहचान अपने घर में है कि दूसरे घर में?

00:55:54तो इसका अपना घर basic हुआ?

00:55:56दूसरे का घर.

00:55:58तो acidic medium में कैसा रंग?

00:56:00नाम में ही पहचान चुपी है.

00:56:02क्या बोल रहों में नाम में ही?

00:56:04अपको दिख जाए यह कैसा इंडिकेटर बेसिक तो एसडिक मीडियम में यह भी है बेसिक मान लो एस यह प्रकार से एक और इंडिकेटर है मेरे प्यारे बच्चों उसका नाम है फेनौल रेड क्या नाम है अब फेनौल रेड एक एसडिक

00:56:26indicator है कैसा है तो बताओ basic medium में नहीं समझे नाम में ही

00:56:31पहचान चुपी है सड़ने क्या बोला लेकिन पहचान कभी अपने घर में नहीं

00:56:37स्कूल में सही नाम बताते हो ना अरे yes or no और अगला इंडिकेटर है जिसका

00:56:42क्या नाम है लाँ क्या नाम है अब सुनो में आप से इन चारों

00:56:47indicator पर चर्चा करूँ घख आपको क्या सचना है यह हैं उसी क्रका कर

00:57:02जांगा तो बिसिकली आपको यह समझना है कि मैं प्रकर करों कि बीस को

00:57:09Now, if you have a color, each indicator will be different from the acidic medium?

00:57:13A basic medium?

00:57:14Or, if you will be different from the pH range?

00:57:16pH range means that every indicator which is the best.

00:57:20Which means?

00:57:21To get the time of your life.

00:57:23To get the time of your life.

00:57:25Before I tell you this, I want to know this.

00:57:26I want to know that you will be different from the computer.

00:57:28Total indicator?

00:57:30The two of the basic indicators are the basic indicators.

00:57:32How is the basic indicator?

00:57:34And the lower two?

00:57:35र मतलब स्रीट किते नियुक्र है कोई हाइपोधिकल आएगा तो कंसेप्क यह लगाया उपर वाले दोनों कैसे इंडिकेटर और नीचे वाले इसका इसतेमाल किस मीडियम में

00:57:48which is from opposite medium in this color and some medium in light color

00:57:55I will give you a first time his range of 3 is 55.

00:58:01How do this range of these range of 3 has a size of 4-6.

00:58:06I let me ask so I need two pairs.

00:58:09I say Frage is the actual value of 3.1 to 4-4 but I wouldn't have

00:58:15I don't know value. I don't know value. I'm going to get a little bit. Hello.

00:58:19How many? How many?

00:58:21It's 6-8.

00:58:25It's 8-10.

00:58:26What do you think?

00:58:273-5, 4-6, 6-8.

00:58:32Every two hours.

00:58:34And all 2 hours.

00:58:36First, 2 hours. Then 2 hours. Then 2 hours.

00:58:38Simple.

00:58:39Just a little bit.

01:01:19common sense which is very very uncommon please please Acha Batche

01:01:38तो मेरे प्यारे बच्चों यह चार इंडिकेटर हाँ इनका अगर मैं अलग से इक्जाक्ट पिये च्रेंज दिखूँ आप लिखना चाहें तो यह होता है 4.2 से 6.2 यह होता है 6.2 से 8.2 और अगला वाला भी रफली 8.2 से 10.2 10.4 के असपास जाता है तो तो थिंग इस कि आप

01:02:08से 5, 4 से 6, 6 से 8, 8 से 10. चलेगा. प्यारे बच्चों एक बात तो क्लियर है कि हम करना है टाइटरेशन राइट और हमें पता करना एंड प्वाइंट जिसमें हमें इंडिकेटर का इस्तमाल टोल कितना इंडिकेटर है चार और यह भी क्लियर हो गया कि उन इंडिकेटर का वर

01:02:38चार तरह के टाइटरेशन करेंगे. चलेगा. सब को कलर याद हो गया? बोलो ना यार. सब को कलर भी याद हो गया और अपोजिट मीडियम में कलर भी याद हो जाए वो इंडिकेटर के नाम में ही रंग में छुपा है. मतलब कोई बहुत हाई-फाई कंसेप्ट नहीं है. ब

01:03:08पुष्ता हो जलते-जलते. अभी तक आपने जितना आइनिक पढ़ा है. अधिक मीडियम का pH साथ से कम की साथ से ज्यादा. और बेसेट मीडियम का? चलो. अगला अगर इसे मैं हमेसा pH स्केल मानता था, और यह 0-14 की रेंज हाया ना, तो मैं जितना 0-1-2 में रहूंगा, य

01:03:38मैं आपको exact experimental value बता देता हूं, और exact experimental value क्या है मेरे प्यारे बच्चों सुनिएगा, जब भी हम करते हैं titration, क्या करते हैं? तो हमारे पास एक खिलाडी होगा, ऐसे कौन होगा? एक खिलाडी होगा, W-A, बोलो भाई. एक खिलाडी होगा, W-B, हाया ना? और एक खिलाडी हो�

01:04:08सतीन, मतलब जो strong acid का solution होता, उसका pH 0 सतीन के बीच में होता, this is a part of practical chemistry, तो आपको practically समझना पड़ेगा, मुझसे reason मत पूछना सर, हम तो 8 भी कर सकते हैं, नहीं, ऐसे नहीं, चलेगा, in general कितना pH होगा? अच्छ, अब बताओ, weak acid इस से ज़्यादा हो कि कम? बोलो भाई, in general इस

01:04:38तो 3 से कहां तक ले लू, 8 ले लू, 8, no, no, no, 7 के 7 से हलका कम, तो 6.9 तक चलेगा, for the sake of simplicity 7 ले क्यों चलेगा? ऐसा समझो, strong गया, कितने मालिक हैं? चोर कितने? चोरों के चोरी का समय fix? अब मालिक के घर में रहने का समय भी तो जान लो, strong acid कब रहता है? अरे, hello, तो जब strong acid �

01:05:08अब बताओ, weak acid कब है? और weak base कब होना चीए? सोचो, 7 से 10.5, मैं 11 बोल दूँ क्या? अरे, चलेगा, मैं वही बोल रहा हूँ, जो आपकी laboratory manual कह रही है, ठीक है? और अगला मैं कह दू, 11 to 14, बोलो, done, अब सुनो, दिमाग में set कर लो, पहला मालिक, strong acid कब रहेगा? 0 से 3, feel कर �

01:05:38और strong base गारा से 4, बोलो, done, क्या मुझे मालिकों के घर में रहने का समय मिल गया? और क्या मुझे चोरों के चोरी करने का समय है? खत्म है फिर खे? अब मुझे बस यह देखना है, मालिक घर में कब नहीं रहते हैं? मुझे यह देखना है, मालिक घर में कब? आओ, एक एक करके

01:06:08I will teach you first.

01:06:09I will teach you how to tell you how to make conclusions.

01:06:10How easy is to see you.

01:06:12Come here.

01:06:13You can write this as a titration.

01:06:14What is it?

01:06:15Come here.

01:06:16Come here.

01:06:17Come here.

01:06:18Come here.

01:06:19You need to keep the house in the house.

01:06:21Now, remember to remember to be strong acid.

01:06:24If you want to be strong acid,

01:06:26then the solution will be more than a pH.

01:06:28This is the same in the code word.

01:06:30I'll say that the house in the house is 0.

01:06:33You need to keep the house in the house.

01:06:34You need to keep the house in the house.

01:06:36Yes, yes, yes, yes.

01:06:38Then, tell me, the dogers would be more 45 than half last day.

01:06:41Think weeks.

01:06:42Three?

01:06:43Yes, yes, yes.

01:07:053-5, 4-6, 6-8, so in this time all the four are ready?

01:07:13No.

01:07:14No, no.

01:07:15No, no.

01:07:16No, no.

01:07:17And this is the reason strong acid, strong base, titration, chemistry, laboratory

01:07:22in the laboratory, because you can use it very easy,

01:07:26you can use it very easy, you can use it very easy.

01:07:28I say, wait a minute, wait a minute,

01:07:30then you can answer it, then you can answer it.

01:07:31This is easy.

01:07:32What do you say?

01:07:33What do you say?

01:07:34What do you say about understand?

01:07:36What do you say?

01:07:38Where do you say?

01:07:40And how do you say to me?

01:07:43What do you say to me?

01:07:443-7, I have to tell me,

01:07:47you say, 3-5 names.

01:07:49And talk about it,

01:07:51I have to say,

01:07:52you are a push.

01:07:55Watch out to have time,

01:07:56when you do it again,

01:07:59you will know that.

01:08:00is strong acid is 0-3 and this week is 7-11. So, who is not at home? 3-7.

01:08:07So, who is the duty of methyl orange? Methyl red. Done.

01:08:13Now, when we use indicator, we can tell you how to use it?

01:08:16Yes, or no?

01:08:18Let's go to a hypothetical question.

01:08:20I have a indicator name, HIN.

01:08:23What is it?

01:08:24And this pH range is roughly, I'll say that the pH range is 8-10.

01:08:29I'll say that the pH range is 8-10.

01:08:30Now, I'm not telling you, I'll tell you.

01:08:32This is acidic.

01:08:34And what is the pH range?

01:08:36Where do you use this?

01:08:38When you use this?

01:08:41When you get the 8-10, when you get the gap,

01:08:45when you get the gap, when you get the transition,

01:08:47when you get the transition.

01:08:48Now, when you get the transition?

01:08:50What will you get to know?

01:08:51You'll get to know me,

01:08:52all types of indicators can be used.

01:09:00All types of indicators can be used.

01:09:07This is the most preferred titration.

01:09:12This is the most preferred titration.

01:09:15So, the question is asked, which titration is the most preferred titration?

01:09:20This is the most preferred titration.

01:09:24Right?

01:09:24Single line questions are made.

01:09:26If there is a question about experimental chemistry, then there is one question.

01:09:29Where will it be?

01:09:29I don't know.

01:09:30This is the most preferred titration.

01:09:35Let's say it.

01:09:36Now, in this whole case, there is a small concept that we say, titration.

01:09:40Titration is very easy.

01:09:43If we read details, it's a good topic.

01:09:47But I tell only a lot of teachers who would know.

01:09:50Let's see.

01:09:52Imagine, come back and say, we're going to see titration.

01:09:56We're doing titration.

01:09:56What are we doing?

01:09:59Are we doing titration?

01:10:01We're going to study titration.

01:10:03Who are we doing?

01:10:04How are we doing idiot?

01:10:05We're using telegram-education.

01:10:06I'm going to explain titration.

01:10:08Imagine, where are we going to do titration?

01:10:10acidic solution. What is it? If it is acidic solution and it is strong acid, how is it?

01:10:15How is pH? Where is it? Confirm. Confirm. Now, you can see what you are doing.

01:10:23You can see what you are doing. What you are doing? What you are doing?

01:10:29Yes. So, you can see strong base and reaction. So, let me tell you,

01:10:34the acid is 100. There are 100 molecules. There is base. How much molecules are?

01:10:4190. And the other two, the other two. When strong base comes,

01:10:46the acid is reaction. The salt is in the inside.

01:10:50If it is like this, the salt is going to be in the inside.

01:10:53But, just like the acid is going to be done, the solution will be neutral.

01:10:59How much will it be? 7. What is strong?

01:11:03It's like pH 0. But, when it is neutral, it will be neutral.

01:11:08If it is neutral, it will be done.

01:11:10So, the solution will be basic.

01:11:12It will be strong base and weak base.

01:11:14So, it will be 7.5, 5.8, then it will be 11.

01:11:18If it is small, small, small, small, small, small.

01:11:22So, pH will be more than enough.

01:11:24Now, you can see this.

01:11:26Here, I have a line of here.

01:11:281-1, 1-1, 1-1.

01:11:301-1.

01:11:311-1.

01:11:321-1.

01:11:331-1.

01:11:341-1.

01:11:351-1.

01:11:361-1.

01:11:371-1.

01:11:52foreign

01:12:01foreign

01:12:05foreign

01:12:07I was like, I'm going to get this.

01:12:09I'm going to get this.

01:12:11So, I'm going to get this.

01:12:13So, first, it's going to be 0-3.

01:12:15Now, 3-3, how much will it be?

01:12:173-3.

01:12:19Is it neutral?

01:12:21Is it 7-7?

01:12:23Tell me,

01:12:25when the next base will be 0-3,

01:12:27it will be 11.

01:12:29You should be like this.

01:12:31But for you to understand,

01:12:33I'm going to make a straight line.

01:12:35You can see it.

01:12:37You can see it.

01:12:39But I'm going to get it.

01:12:41But it will be a straight line.

01:12:43But it will be a little tilted.

01:12:45Now, you understand?

01:12:47What is it?

01:12:49Now, what is it?

01:12:51Which curve is 0-3?

01:12:53Is it a transition curve?

01:12:55Transition means that when the house is in the house.

01:12:57So, whenever the titration curve comes,

01:13:01there will be a zone that will be

01:13:03where we can use indicator.

01:13:05This is the range where we can use indicator.

01:13:09This is the range where we can use indicator.

01:13:11This is the range where we can use indicator.

01:13:13This is the range where we can use indicator.

01:13:15This is the range where we can use indicator.

01:13:17This is the range where we can use indicator.

01:13:21This is the range where we can use indicator.

01:13:23This is the range where we can use indicator.

01:13:25This is the range where we can use indicator.

01:13:27This is the range where we can use indicator.

01:13:29This is the range where we can use indicator.

01:13:31This is the range where we can use indicator.

01:13:33This is the range where we can use indicator.

01:13:35is

01:13:37a

01:13:39point

01:13:41to

01:13:43use

01:13:45two

01:13:47questions

01:13:49and

01:13:51you

01:13:53will

01:13:55ask

01:13:57what

01:13:59you

01:14:01How many titrations do we have? What do we have done?

01:14:06The next step is what we should do.

01:14:08We should take this step.

01:14:10We should take this step.

01:14:23We should take this step.

01:14:26So, my friends, total 4 titrations.

01:14:28We should take this step.

01:14:30You can see that when you don't have a titration,

01:14:32when you don't have a titration,

01:14:34when you don't have a titration,

01:14:36that's it. Right?

01:14:37Easy.

01:14:38We should write the next titration.

01:14:40SAWB.

01:14:42We should write the titration.

01:14:44SAWB.

01:14:46SAB.

01:14:48SAB.

01:14:50WB.

01:14:52WB.

01:14:53And it looks delicious.

01:14:56How many of you know that région is born?

01:15:07secos.

01:15:09The following indicators you can use.

01:15:11SAWB.

01:15:13We should like this,

01:15:15now we're gonna do it.

01:15:17Come here, now we're going to make this.

01:15:19Titration curve. How many kids can we make this logic?

01:15:22We're going to make this 0-3.

01:15:24So, 1 line will be 3, then we're going to make this.

01:15:26Hello?

01:15:28So, I'm going to make this 1 line, 3, 1 line will be 7,

01:15:31and we're going to make this kind of titration.

01:15:34Here we're going to make this pH, here we're going to make this.

01:15:38Of course, we can study this,

01:15:40but we don't have to learn the practical chemistry.

01:15:42We're going to make this very first question.

01:15:44the first question we will give you simple. We will give you so much the depth. Because

01:15:49here, this is what is strong? It will be here. It will be here. It will be here. And

01:15:56what will be the solution? And the solution will be the basic. And you all have to

01:16:00solve the problem with the problem. And in the world, there will be a case of the whole

01:16:04titration, the other, 50% or 70% can be very numerical. In the case, we have a

01:16:10see your idea.

01:16:11I'll go ahead and see your idea.

01:16:12And then you will be fairly

01:16:13about the transition from the three seven.

01:16:16Tell me.

01:16:17Summer, tell me,

01:16:19when can I have the ACOE?

01:16:21When I have the ACOE?

01:16:22No, because I have the ACOE?

01:16:23When I have the ACOE?

01:16:26You have the ACOE?

01:16:27That eight to nine four seven seven seven seven three eight seven seven seven eight eight seven seven eight eight.

01:16:33When I have the ACOE?

01:16:34When I have the ACOE?

01:16:35It's time to come out with ACOE.

01:16:37Back to the ACOE.

01:16:39I said, yes or no, let me write. Indicator, usable range. Now I'm going to create a graph. I'm going to tell you quickly. The next titration is which one? Weak acid, strong base.

01:16:51I'm going to tell you. Weak acid. Weak acid. Weak acid. Weak acid. 3-7. Now I'm going to tell you exactly 7-7, but it's a simple number.

01:17:04So simple about 7-7, I'm going to tell you. Strong base.

01:17:11Now tell me, is your data when credit cards.

01:17:28It's Red.

01:17:34sorry sorry sorry volume of base huh volume of base

01:17:42phenol red and the last one is phenophilic

01:17:46okay so I want to learn these things very easy and you can learn the graph if you learn

01:17:51something you can find a point where the transition happens and what is the transition

01:17:55we can use indicator are a quick titration but I can't answer the little and next and the last

01:18:03little little

01:18:06next and the last titration that is weak acid weak base

01:18:12next and the last titration weak acid weak base

01:18:19yes

01:18:24yeah

01:18:26can I haven't said here

01:18:29week acid three six percent

01:18:44White acid is not on the right side of the final side of the bed,

01:18:47and now we'll open.

01:18:51We'll get a little bit smaller.

01:18:55And now we'll explain,

01:18:57we'll present our parents' name.

01:19:00Our parents are not on the left side of the bed.

01:19:03We'll tell you what we can't learn from now.

01:19:05We'll tell you that the kids can't learn,

01:19:08we'll learn more about our parents' Kingdom.

01:19:12is the only option what we have to use is phenol red or co-option

01:19:26but this is the most

01:19:42preferred titration or least preferred

01:19:44लेखेगा next point star बना के this is the least preferred titration

01:19:50बोलो आसान है अच्छा अगर मैं इसका titration कर बनाता तो बोलतो उसमें

01:19:59range बहुत जादा आती बहुत कमाती पक्का और यही कारण है जब भी इसके graph बनाए

01:20:04जाते हैं अगर मैं graph बनाने कोशिस करूं अगर तो एक point कहा है

01:20:08तीन से साथ हाया ना तीन से साथ और एक point है साथ से उपर यानि इसका जो graph बनाते ना तो अपन कुछ

01:20:16ऐसे बनाते यह 3 है यह 7 है और एक जार हमान लो तो इसका graph में कैसे बनाता थोड़ा ऐसे होता हलका से

01:20:23यहां पर स्टेट लाइन होता और फिर कुछ ऐसे होता बोलो हाया ना यानि यहां पर जो इंडिकेटर की usable range है वह बहुत कम है राइट और यही कारण है कि दुनिया में कभी भी आप देखना

01:20:33स्कूल की लबरेट्री में तो वीक एकिषड वीक बेस टाइटेशं करते ही नहीं है नहीं क्यों क्यों अर्राइगा और बच्चों का तो ऐसे एसबी में ही तो एरर आता था तो सोचो

01:20:461-2-1-2-2-2-1-2-1-2-3.

01:21:16point and don't know me some time there's neutral her solution of course

01:21:20you're ready to come by station carnival and point

01:21:23part of the technique of the system I'll go get it together

01:21:26yeah I'll go yeah I'll go and I'm I'm a light I'm not

01:21:31for me I'm a total Ketra indicator I'm going to be

01:21:34going to be here to have indicator of the pH range

01:21:38of the pH pKa in the body of the use of the

01:21:41the no working condition below high enough
