How to Find Oxidation State 🔥 | Redox Reaction | Class 11 Chemistry | Easy Tricks @a2zpractical991

Hello, kids, how are you all? Inside the redox reaction we are going to observe today The topic that exists Finding the Oxidation Number I mean, the oxidation number of any compound How to find out I will teach the children very lovingly. You must keep your full attention on the board. Only then will you fully understand everything. Come on, let's get it over with first, I'll give you I'll go over some rules. After reading those rules, your mind will finally open up. Let's see what it is. oxidation state if you have any To find out the compounds There are certain rules you will need to remember. I will explain to you very carefully today, and I will also make the rules clear to you. It will become clear, the children who are free elements Aren't they, like, your sodium, like your H 2 has been achieved, hydrogen seal is connected with them, no issue at all. It shouldn't appear as if sodium will show up to you, okay? You should not be connected to that number It's zero, so just memorize it thoroughly, the second one What does it say if there is a single atom or ion, okay, then it is itself It will be equal to the charge. You'll say, sir, what is this? Single atoms, ions, and It will be equal to the charge now, so please pay attention like this You take sodium plus 1, kids Plus 1 charge, right? So here, the oxidation of sodium The number will come, it will be plus one, okay? I think everyone is getting it, so the more charge that remains on it, It will become equal to its oxidation number. Therefore, chlorine has a minus 1 charge above it. Thus, its oxidation number will become -1. Alright, this is well known to all the children, keep moving forward, children As you probably know, when your Peroxide is what undergoes oxidation. Valence is minus one, which is a superoxide. The oxidation state of oxygen is -1, and in superoxide, it is Remember, most of the time in oxidation, we don't No, it's just the minus 2 oxygen one, and second Last point, tell me, okay? Hydrogen is usually The +1 oxidation state occurs when it is non- Lives together as if writing like this, Malo Child, you know hydrogen is your non-metal. But now comes the hydrogen, which is in the +1 state. It is the point state. There are certain cases in the state where yours Hydrogen is connected with a metal. You know, at that time, the hydrogen that exists reaches the -1 oxidation state with metal minus 1 and with non-metal Plus 1, all right, they'll all know about it afterward. If you're given any compounds, that's fine, As if you were given such a compound, KMnO4, okay, and on top of it, you don't see any charge indicated. So this is a neutral compound, so child, you all calculate. And what will you write for oxidation state? Zero, but this very one, Look, if your compound is neutral, then the one It will remain, it will come to zero, what will the oxidation state come to? It will come zero, I'll tell you how, just like its value, Who will write the value of this, and the oxidation state? Has everyone found out about these rules already? Now you can easily You can determine the oxidation number. Because I'm doing it, it's very easy. It will be done for you, come here, let me do it for you. I teach, yes, some things It is extremely important for me to know because If I'm making this video, then my M That is, give children good knowledge. It's fine here, let's go, you know, what's the point of some things, right? Listen carefully, child, read out the charges here How much is approximately everyone's plus three, and carbon? The family that has four, it's carbon's. It will also come, silicon, etc., so for nitrogen, minus three. It's oxygen with minus four, oxygen family for everyone And fluorine has a minus 1, okay, so the fluorine family It's minus 1, just remember that a little, if you don't know it Just do this one thing: if anyone's outermost shell has If there is one but up to three electrons, the child will lose that much. And the more positive charge will be induced on it. It will accept one electron, and as many electrons as one electron The more he accepts, the greater the negative charge will be on him. Which charge will come? Negative charge will come. Okay, clear. Let me tell you something: just like sodium, you are. The child has an atomic number of 11 for sodium. So how much will it be? 2, 8, 1 It has one electron in its outer shell; it will lose that electron. Which charge will come above sodium? plus 1 But that same child, when I talk about fluorine So, the atomic number of fluorine is 9. What does 9 mean? How much do you feel inside me first? 2 and 7 It is coming within the rules, falling between 5 and 7. Thus, it will gain one electron to complete the octet. Like a child, it will take one electron So, a minus 1 charge will appear on fluorine. Now I can take everyone toward oxidation. You can all find out the oxidation states of the elements. Here comes your first question here. reduce the oxidation number of sulfur in the following species Alright, what is the oxidation number of sulfur? In this example, you are to inform me now Let's see. The child whose oxidation number you need to find out You will always write his x After that, the other two elements come; please take a look at them. And how many times is the child, two times, is it? After two times, you should have the oxidation state of that element. Alright, the oxidation state of that atom should be, So, the oxidation state of oxygen, okay, and anything above it Charge is there or not, so what will you put? Zero, Now, look at x plus 2 into the oxidation state of oxygen Oxygen's oxidation state of minus 2 is equal to 0 So x will be equal to what? 4 Okay, how will 4 be? Will it remain in minus? What will happen there? 4 What is the oxidation number of sulfur here, kid? Plus 4, that's correct. Okay, let me show you by doing it. Look, for sulfur, whose value you need to find out, write down x, Plus 4 times, oxygen is how much for the child, minus 2, Okay, after that, look here, the overall charge is also given. How much is given, minus 2, so write minus here with affection, So this score 2 will become how much, 8 minus 2, So x is equal to minus 2, plus 8, right, so what is x equal to Listen carefully, child, listen carefully—whose oxidation are you talking about here? State and how to calculate it — listen carefully, you all know calcium, Calcium belongs to the alkaline earth metals family, yes, calcium belongs to the alkaline earth metals family. Beryllium, magnesium, calcium It belongs to the second group. What is its oxidation state? It's plus 2, okay? You need to find out about Posporus. Alright, let's assume x How much is plus 4 times oxygen, child? minus 2 is correct, okay and it amounts to no charge having been given at all Then what shall I take? I'll take 0. Now listen, child This PO4 given here, not overall 2 is written, so the child has written the whole Close the square bracket here, you have 2 will have to be written, okay Plus, come on, listen: if three-time calcium is given, then three times How much is calcium? It's minus two. Okay, now let's go. I will ask everyone a very, very loving question Fine, okay, how much will it be for four to go? Okay, make it two zero. Alright, this two x minus eight at two would become six. To zero and this three to go how much will it become six, okay, now let's move on to this If you subtract, how much will it be? Three minus two, okay, here. But the calcium ion is plus two, okay, okay Now, if you subtract this, how much will it become plus? It will become two ten; as for zero, what will happen to x? ₹10 Pan X Pan Here, the oxidation of Calciem How much is the poster frame for the Jasem set, how much has it come out like Okay, clear, everyone understands now. There aren't any mistakes here, are there? Okay, Let's move forward and go through a few more questions. Calculate the oxidation state of the underlined atom, child, the underlined atom's We need to calculate the oxidation state; let's do it. Here, sulfur is underlined, so it will become x. Plus, what is 4 times oxygen? Who gave the overall charge of minus 2? Zero, come here, kid. You gave hydrogen twice now. How much hydrogen is that? It happens, one, okay, come on, do it, man, I don't think it's that easy to tell you Necessarily, 4 times 2 becomes 8, plus this 2 equals zero, so If x minus 8 is equal to zero, then what is x equal to? How much does sulfur cost at the office here? Will go to the children six, let's find out hydrogen here If you want to do it, let x be the value, okay, plus three times oxygen How much is it minus 2, if no charge is given? What is zero and hydrogen? One times three is three. How much will it be: minus 6 plus 1? Okay, so x equals So what will happen to minus 5, x equal to what It will become minus 5, okay? Is it clear to everyone? Okay Last ones here are good, phosphorus is the last one. If it is given, and underlined, then find it out. A plus sign needs to be added now. How much will it be minus 6 plus How much will it become here? But let's do three more. Run it here, just stay and do the thing Just remember, you people will always be Cr. Cr vocal, that's just how it is. Let's see, it needs to be underlined, chromium, this one If you want to find out, multiply 2x by 4 into oxygen's amount, how much it becomes minus 2 over All charges zero, then look after that, potassium kid To which family does potassium belong? Lithium, sodium It belongs to the family with potassium plus one. If you remember your fake ID, how much is the charge for two-time potassium? It's plus one, okay, so 2x, how much will it become when charged? 8 is equal to 8 equals 0 and this plus 2 is correct So 2x is equal to minus 6 is equal to 0, so 2x is equal to 6 So x is equal to 6 minus 2, so x will be equal to 3 So, the chromium (Cr) charge here today will be 3. Let's find out the sulfur here, the compound is H2S4O7, correct? It will go, find out x, the child, but that is 4 times So it becomes 4x, okay, plus 6 times oxygen, so minus 2 equals zero. And here, the child has hydrogen twice, one hydrogen having one. Six twos make twelve, so twelve minus twelve is zero. This will become two times twelve, which is zero, and this 2x will become so, then if you subtract, how much will it be? It will become minus 10, which is equal to zero, okay? 10 minus 1 will go to a practitioner And the door of the four worlds is that Nothing's gone wrong, is it? Maybe it's correct, but let me check if there's any mistake somewhere in the value of x. And we move forward, the last one Chromium has a plus oxidation state. Like, figure this out, okay? Plus two times Chromium requires you to write 7 into The overall charge of oxygen is minus two. Now here. Whose charge is this child? Overall Charge you minus two write down What will happen, then what will happen? It will go, okay, so here So here it is, everything for you Try and tell me, try and tell me How did it feel, keep going Videos, please give me your feedback, it means a lot to me It's more important because of the way I'm reading. Do you understand how much I am for this? If I work hard, it becomes absolutely essential for me to know this. Please like the video and let me know in the comments How did it feel?
