 See alpha is less than alpha you want now see alpha you will calculate h Should we skip this you can do that also Do an execution Calculate pH of 10 to the power minus 2 molar ls3 10 to the power minus Because k defines the weak acid yes So whenever weak acid behaves as a strong acid Strong acid yes in terms of dissociation It will dissociate completely So if you see alpha Yes H plus You can take H plus or H plus 10 to the power minus H plus concentration has 10 to the power minus 6 Yeah Right Oh alpha that was okay Next is just check is there any difference Now soliton plus 10 to the power minus 4 molar For this question for ls3 10 to the power minus 4 molar ls3 So you can't take it Yeah So you can't take it So calculate kb So it's like 13.66 12 to the power 21 13.66 How much it is? Alpha How do you take this? Sir, 5.5 is not 3.5. No, it has 5. Come. 5.5, yes. 5.5. What? What 9.5 is the PHS? Sir, what's the other point? What PHS? P.H. is 6.7. No. What do you mean by 0? What? Acid. Okay, so let's follow the correct answer. 5.5. Alpha 0.5. Alpha 0.5. No, it didn't. What's the other point? What's the other point? 7.3.6. 7.3.6. 7.4, yes. 1.7. P.H. No. 1.3.3. What's the other point? What's the other point? What's the other point? Sir, 9.5 is not 3.5. That's a matter. Why? When it ends over here, it's normal. I didn't know it was that bad. Yes, sir. What do you see? 4.5. What's the other point? 0.358 is the alpha. Yes. 3.5. 3.5. See alpha? Yes. That is 3.5. Yes. Can we consider what to? 0.358. 0.358. 0.358. 0.358. So P.H. 0.358. 0.358. 0.358. Sir, give me 15. 10 bar minus 7. So this you can't do. Okay. What's the other point? 8.3.6. 8.3.6. 8.3.6. Sir, it's lesser than 8.3.6. 8.3.6. 8.3.6. 8.3.6. So that's this? 7.3.6. 7.3.6. 8.3.6. 8.3.6. 7.3.6. 8.3.6. 7.3.6. 7.3.6. You can see. Sir, give me 7.1 something. 8.2. 7.3.6. 4.6. 8.3.6. 8.3.6. 2.3.6. 8.3.6. 8.3.6. Sir, the minus-canon power. 4.6. So you have right? 8.3.6. Oh. 9.4. So 1.952 is alpha. 8.3.6. That's 0.95. No. 0. 6.935. 0.8. 0.935. So 0.952 is alpha. No. 0.95 is that far? No. Why? Because that problem is that far. Okay. No. Okay. Thank you. Thank you. Sir, I am the first one. No. No. I am the only one. I am the only one. Okay. I am the only one. I am the only one. I am the only one. Why? Shut up. Sir, that is the end of this. I am the only one. Oh, shit. What is that about? The circuit. Mesh. What is that about? One now, I told you, how would it be at this time? I will find some way now. Minus, okay, that's 3 plus minus. At the p square minus 4 is 3. Minus. One plus half s. We will ignore this thing. First one we will take. Alright. This is good. Exactly. Okay. Okay. Okay. Okay. It is like 0.618 into 10 to the power minus, sir. Are you ready? Because of this base, once I get some extra space, it will suffice. So what it is? 1.618. 1.618 into 10 to the power minus 7. Can you calculate dh? 7 minus 0.618 into 10 to the power minus 7. 0.7 is minus 5. 0.618 into 10 to the power minus 7. 0.618. Just 0.618. No, this is 0.618. Sir, this is the water. 0.618. 0.618 into 10 to the power minus 8. This should be 0.618. Sir, what is the time? 0.618. Okay, this is the second. 0.618 into 10 to the power minus 5. This is 3 times 4. Okay. this also, here you are using the alpha square and in case of kV, what is the question is? 7.8 6.8, subscribe that, okay. Next one is? 7.8 Okay. 7.8 Okay. 7.8 D is equal to D. 7.8 That's it. No. Yes. No. No. No. No. No. Come back to this. Come back to this. No. Sir. Sir. No, no. Sir, I do, you represent some of the effect of water in that, if you get any effect of water. Effect of water for the system? If you dilute it enough, then it becomes alpha water. Water? Yes, you are saying. So why? I am just saying that alpha is very small compared to C, and in secondary alpha, so much. Let's see what it is. Not direction is saying it goes in the air. Ok, derived, derived. So, it's very important if you do not go for the water then all the water will come out. So, you can just say it like this. Sir. Sir, without any assumption. No. You have to take an assumption. First thing, assume that... Alpha is small. Alpha is small. Second thing, this will be... You have to add... That's without assumption. You have to add to the water. You have to make it as one way or another. You have to make it as one way or another. It's... It's as one way or another. It's not that... How do you... You have not taken... C1k1 and the river. Is it 4k1? We said that... No, it's not 4k1. No, 10k1. Sir, a question. What? We said it is 1 meter. Sir, a question. I know. We did it. But, I know this. C1k1. What? I know. C1k1. This is the... C1k1, okay? C1c1. How much? I know. C1. Okay. C1. You got right, okay? No. Okay. So, it is... I repeat. So, it is C1k1. C1 alpha 1 plus C1 alpha 2, C1 alpha 1 plus C2 alpha 2 you can write. Now, K1 is C1, into C2 alpha 2, into K1, C1 alpha 1, into C1, C1 into 1 minus alpha 1. C1 into 1 minus alpha 1. See, I am writing this. You can't jump without writing the equation. Sir. You can't write like C1 K1. C1 K1 is okay. Now, this is a C1 C1 path. It's not. So, alpha 1, you may get alpha 1 using this. No. Substitute value of that. Are you getting what I am saying? Sir, I think I can go down the path. You get finally what you want to do. What? Sir, I am getting it. How do you substitute it? Well, you substitute it. Okay. What? In this C2 alpha 1. Can you do C2 alpha 1? By C2 and 1. By C2? By C2. You got this equation? No. No. After doing this. C2 alpha 2. C2 alpha 2. Yes. Now, K1 is almost equal to C1 alpha 1. Just substitute this 2 and calculate. Who has not? There is alpha 1. Alpha 1 with what? Yes. I am not doing this. I want K1 by K2 into alpha 1. I want to remove one of them. So, in terms of what is alpha 1 by K2? Sir, K1 is alpha 1 by K2. Alpha 1 is K1 divided by? K2. K2. K2. That is what I am asking. Alpha 2. How the hell is root count? Sir, I think that we do want to. Why do you want to? Sir, but how is root count in the equation? You are not, you are not. This is fine. Yes, that is fine. K1 equal to C1 alpha 1 plus C2 alpha 2. Yes. By C1 alpha 1 plus C2 alpha 2. Yeah. How? Oh. We get K1 equal to C1. There is a. I got alpha 1 plus C1 alpha 1. We get C1 alpha 1. We get C1 alpha 1. We get C1 alpha 1. We get C1 alpha 1. Oh. How? Sir, you just need a listen. Yes. Thank you. So, K1 equals to C1 alpha 1 plus C2 alpha 1 by K1. Why? It is a plane. So, it is the simplest K2. Sir, this is fine. Really? Yeah. C1 alpha 1 plus C2 alpha 1 by K1. Yes. Yeah. Yeah. Yeah. Any doubt? Any doubt? Any doubt? Any doubt? No, we solved it. We get alpha 1 by K1. So, we get alpha 1 equals to K1 divided by K1. Okay. Yes, sir? Yes, sir. Okay, now. Now, what is the type of being acid? So, like this. Yes. Okay. Expression comes here. Can we say X3 over plus? Concentration. Oh, it's my... Can I do it? Can I do it? Can I do it? Can I do it? Can I do it? Concentration. Concentration. Concentration. Concentration. Concentration. Concentration. Concentration. Concentration. Okay. I'll try a few things. What's the time? What do you think? What do you think? What do you think? Okay, next question. Mixer of strong acid. 0.1 over X3 over plus? 0.1 over X3 over. Can you look at the... See who's the number? Let's look at the... Yeah. So, 0.1 over X3 over... 2 units of... 0.1 over X3. So, I'll do it this way. Yes. I'll set it with 0.1 over X3. Sir, K... Sir, it is in the graph. Sir, you get... Sir, the graph is 0.9 over X3. Sir, it is very close to 0.1 over X3. Sir, it is very close to 0.1 over X3. It is 1 minus 0.1 over X3. Why is that? I'll set it with 0.1 over X3. Or 2 steps. 2 steps. Yes, sir. 0.5 over X3. 3 steps. What? Okay. So, then... I'll complete the graph of X3. Then, 5. So, it is 0.014. So, the total is 0.1 over X3 over X3. 5. 5. Okay. So, it is 0.5 over X3. 0.5 over X3. 0.5 over X3. That's the principle of the... 0.1 over X3. 0.5 over X1. Yeah. It is more than 0.5 over X3. Is it clear? Sir, we need to correct this. Because... Can I say that whenever a mixture of... strong acid and weak acid is present, dissociation constant is very, very less. So, if you have all the weak acid... All the weak acid... Affirmative for you. Nothing. Nada. 0.014. Okay. Sir, 0.014. So, 0.6 into 10 to the power of X4. Is it 5? Yeah. 10 to the power of X7, sir. Let's do this. I'll give you a point. Yeah. Concentration of X3... into CR1 divided by CR1 minus the power. So, it is this. I did not do that. X plus is given to you... 10 to the power minus... 6 into 10 to the power of X8. Yeah. Sir, can we measure the power of X2 to the power of X4? Sir, why can't we measure the power of X2 to the power of X4? 2 into 10 to the power of minus 5. Yes. So, H plus... 2 into 10 to the power of minus 6. Okay. Let's get... Sir, 0.014. What? Let's get... 100 to the power of X8. Next question. 10 to the power... 10 to the power of X8. Sir... Why buddy? So what is X8 to the power of X9? Don't get scared. Yeah. So please emphasize on it.ð So, anymore? Yes. All of them are two startup. Mm-hmm. What do we do first? So, what exactly happens in this stage of finding? What happens again? What's clear? What do you do? So, just like this... You see, in this view, 10th of November, 10th of November, 10th of November, 10th of November, 10th of November. C1 plus 1.5. C1 square plus 2. This is important. Yeah it's exactly like that. Exactly like that. You have to control it. What? 2.8 2.8 2.8 2.8 2.8 2.8 2.8 2.8 2.8 2.8 3.8 2.8 2.8 2.8 2.8 2.8 2.8 3.8 3.8 2.8 2.8 Bye.
