hey kids how are you all my self amit mahajan and welcome you on this Incredible Platform of Physics Wala Son, today we are starting a very Very short but very interesting chapter whose name is redox reaction and volume metric analysis yes good afternoon good Afternoon Good Afternoon everybody pravit saying sir any single girl here yes private they must be so single Girls You can continue the conversation The rest of them which is not like the Prabat you can also concentrate on reading ok end Friend, it will take less time, we don't have much time will apply this chapter okay okay let's start again today Keela Which oxidation and reduction occurs first? They talk about oxidation, which occurs in the beginning The definition was spoken in ancient times in that it was the addition of oxygen or removal of hydrogen add oxygen to something or the hydrogen is removed from it It used to be called oxidation but for this what was the problem in the definition that chemical oxygen or hydrogen in the reaction One or the other of the two things should be Let us assume that there is oxygen in the reaction. no there is no hydrogen then how will tell whether oxidation or reduction has taken place This has happened and that is why a new definition has been given Oxidation occurs whenever loss of electrons if it happens then what will it be called that is would be called oxidation, for example whenever sodium is It will loose one electron then on sodium there will be a float if there is calcium if these two If it looses electron then it will have + 2 Whenever there will be loss of electrons It will be written on the product side that there is oxidation Whenever oxidation occurs Then either the positive charge increases on the atom or the negative charge decreases like you can see here The charge is zero, above this there is a plus and the positive charge has increased on it is zero There is L2 on this, the positive charge increased on this If it is zero then it has +3 then the positive charge increases Sir, those with negative charge are also gone Example 2: These nos negative gives you + 1 electron here has charge -1 It is zero, the negative charge has reduced here also the charge is negative and here oxygen the charge on it is zero what is the negative charge it has happened it has reduced okay so what do we They are saying either the positive charge will increase When the reactants go from products to negative If the charge is less then what will we say How do we know if oxidation has occurred? how much the positive charge will increase or how much The lesser the negative charge, the more electrons Loss you will be number as much left in number line system Moving from the right hand side to the right hand side charge on charge do you all have number line I know the system, yes sir, all these zeros here All the negatives are positive here There are integers like here See if it has lost an electron yes then move one charge from zero because The charge on it was zero, from zero to float well then it will have a charge pass It has lost two electrons and the charge on it How much was zero so two left of zero two Move right from zero to one, one to two, ok A flat will appear on it like this one If you loose an electron then see that it was -1 look carefully -1 was -1 one left from -1 I will move it to the right, it will come to zero, see The charge above came to zero, above this there was -2 -2 so If you move right two times from -2 then it will be zero. What will be the charge on this if it is zero then this also you got to know okay sir same thing if you Tell me about the reduction in old times The definition I had was this, ri o There was oxidation i.e. addition of hydrogen or the removal of oxygen from a hydrogen let it be added come son sorry yes come can anyone Hydrogen should be added or oxygen should be removed If he goes, what would we have told him? Reduction Let's say okay this definition also only then Applicable when chemical reactions take place be it oxygen or hydrogen if oxygen there is no hydrogen so this reaction This definition is also not possible because The reason a new definition was given was the gain of Whenever there is gain of electron then what will happen, there will be reduction and whenever there is gain off electron will increase negative charge will or the positive charge will decrease it will be ok just see this whenever you gain The off electron will be on the reactant side It will be written that S has gained one electron then the oxygen level will be negative If electrons are gained then oxygen pays two Nitrogen will lose three electrons If you gain then three negative on nitrogen The sodium ion will gain one electron If this is done then sodium will turn calcium to positive gained two electrons then calcium You will see it in the first three examples If you see, the negative charge goes from -1 to Ro increased from 0 to -2 negative charge increased went from zero to -3 negative charge increased Here the positive charge goes from PSU to zero The positive charge from the plate got reduced and went to zero decreased okay so either the positive charge will it decrease or the negative charge will increase but sir How do we know how positive it is? will the charge increase or how much negative charge The number will increase exactly, you have to write its reverse of electron guess to the right in the number line where will you move to the left Will the electrons go So where do we move from in the number line system right hand side to left hand side and charge like this is the number line The system you See here the charge is zero so there is one electron gain zero one electron If you have gained then move from right to left once We will do it, it will cost -1, the charge on it is zero It gained two electrons, so from zero to two I will move right to left - 2 will come in this is zero it has gained three electrons So I will move from right to left three times, the same is the case here also sodium p will go to ro will go from p to ro then this + He moved one right from there and gained two if you have done it then + 2 will go twice ok my I have understood from my thought how much charge to write what is the definition of oxidation and reduction okay now we'll talk about redox Who will you call a reaction like this, son? In which oxidation is also taking place as well as Reduction is also happening, what will you say about it that is redox reaction reaction in witch oxidation End Reduction akar simil nice we will call him that is redox reaction can you give some example yes, can you give a simple example But we have seen many examples of this just now. reading Do you see this charge here? yes there is a row on it there is a float on it This pay is -1 You are watching from Ro okay it went to pv only positive charge has increased absolutely the positive charge will increase Or if the negative charge is less then we will say Oxidation is well done, if you see this Here this row went from -1 to negative The charge increases when the negative charge increases or reduces the positive charge then we what do you say if it gets reduced then this is a redox reaction in which the Oxidation has occurred and reduction has occurred Ok son next we will talk about that is What will the oxidation number tell you? about oxidation number okay about the oxidation number in What is the oxidation number, for example, suppose someone also take the molecule i kept co2 this is the structure of co2 yes sir Everybody knows what this is Carbon has formed four bonds here yes there are two double bonds formed like this You can also say that if I buy these four bonds Should I break some charge on carbon? yes it will come what will it be called carbon oxidation number similarly to this oxygen has formed a double bond yes or two Bonds have been formed, a double bond is also said can you tell me what i can do if this bond If I break it then there will be no charge for it yes What will it be called, its oxidation number Similarly this oxygen if I break the bond If I give it to you, will there be any charge for it? Yes, that what will it be called oxidation number okay now we have to do oxidation number what number do you want to do son to calculate to calculate We know the rules to calculate the what should be the first rule son when Any element is in elementary state hai elementary state address did you understand yes sir when He is alone, if he doesn't have two bananas Its oxidation number is zero if any Ask Hydrogen Elementary Hydrogen what is state h2 oxidation number Zero iodine has a2 oxidation number zero b oxidation number of br2 zero oxygen's o2 oxidation number is zero And who else survived, son? Someone else comes to mind. sodium oxidation number being zero chlorine cl2 oxidation number zero helium You can also say that the oxidation number will be zero when an atom reacts with its own atom An atom has formed a bond with its own If it has formed a bond with the atom then its The oxidation number will be zero i.e. iodine the bond it has formed with iodine If it is made then what is its oxidation number will be zero for that bond carbon bond is formed with carbon only then that The oxidation number of the carbon for that bond what will happen it will be zero only, come on understand this It's okay whenever someone is alone What will be its oxidation number? It will be zero Now let's talk about when the bonds will be made If bonds are formed then the oxidation number will be different like that of first group metals Do you know who the people in the first group are? Yes Sir, everybody knows Leena I appeal to God yes sir lithium sodium Potassium, Diium, Its in Combined State Combined state means when it is connected with any If so, then their oxidation number is Please sir give an example, example here Lithium chloride formulated compound Its primary purpose is sodium bromide. It has has made up its P is one then P here if two sodium If it were there I would have said exactly two's plus two even if it would have been one then still it would have been plus v Similarly, those who belong to the second group You would also remember that the son asked for a car and a scooter. Are you okay with our time, this mnemonic If it used to happen then what would have happened then it would have been t is son He asked for a car and scooter, our father is crying, right? There was a generation that started asking for something from father If you do it then father will have to endure your own curse If we start, you know we have I don't have money, where will I earn my bread from? I am here but this generation has changed It turns out that the mnemonic in use these days is this yes son asks for a car and scooter, is the father ready? This is called the generation gap They call it generation gap, maybe it is their oxidation What will be the plot in number combined state how much plate in like calcium chloride Magnesium Plat in Magnesium Sulphate ok this is called generation gap you are absolutely correct you are right Similarly, those who are of 13 groups these are pangan potatoes and carrots in this bag their is fine When it is trivalent in combined state Trivalent means three bands have been formed so these plus th oxidation state show Like bcl3, boron has p3 in it, albr3 has p3 in it How much is aluminium, that is plus 3 don't do it like thallium is thallium if Plus 3 is associated with I mean three if it has happened then it is P3 but if it happens with only one If it is called monovalent then it will float Sir, I have also read that thallium has a lot of flux It is stable due to inert pair effect very good very good if all this If you have read these things then 16 groups Let's go specifically to that one, leave the 16 groups I talk to 17 because they are more Important 16 So I'll talk about it anyway I will find out who was from group 17 tomorrow Outside Mother aunty is there in their combined state How much is the minus sign Accept Inter Halogen Compounds In inter halogen compounds except Sir there is minus, can you give an example Like look at this, Lithium Chloride has modified If you have prepared it then this will be -1 Sodium Chloride not is -1 sir this is inter halogen What are the compounds formed when two halogens combine? are attached like icl3 iodine also halogen is it also a halogen in this case what is it The one which is more electronegative will have So it will be -1 only sir find out the other one I will learn to find out, I told you Son, what is the meaning of inter halogen? How much hydrogen is there in the combined state Would How much is there in combined state Did you understand the combined state when with someone The bond is formed depending on the metal then hydrogen is maintained with The oxidation number of should be kept -1, sir example Look at this with sodium hydride metal is connected -1 calcium hydride two Hydrogen is one's -1 two's -2 will be me I agree but only one name is always written on top and if this hydrogen is combined with whom is that non metals then with hydrogen Oxidation number will float sir example this Look, h is hydrogen connected to non metal it has happened that hno3 hydrogen is non metal is associated with the float h2so 4 hydrogen that is associated with non metals float ok and let's talk Son Fourth Oxygen Combined State of Generally its oxidation number is -2 If you talk generally it is -2 sir You can give many examples you can give it like see this h2o -2 of an oxygen h2so 4 one oxygen's -2 head here so There are four oxygen atoms, yes the sum of the four is -8. I agree, but I am saying that one I have written about oxygen above -3 -2 hno3 one oxygen has -2 yes they have three oxygen I agreed that it would be -6 but I said it up it is written ok but Sir but sir there is another issue with oxygen which oxygen is that when in oxides then its oxidation number is -2 For example, we have read calcium oxide etc. but if this is on oxygen will be in oxides So its oxidation number will be minus 1 sir You can give an example, you can definitely do it for example hydrogen per oxide is a There is a mine of oxygen There is a mine of two oxygen Sir and any sodium oxide is an oxygen ka mive will be the mive of two oxygen i value There is another such T E Super oxide with oxidation number minus half it happens sir please give an example of it like k2 rb2 c Sorry cso2 it contains minus half of one oxygen the multiple of two will become the multiple of one minus half Minus half of one Sir, I am a tiny bit small I'm a cute little kid, how do I know It'll do, I'll appear in the paper as anything How will we know if it is an oxide? oxide that this is super you are a teacher to you So you know it's called peroxide It is called super oxide, isn't it? It's been so many years that I've been teaching I'm a student so I don't know anything So how do I know if it works here We have to take the minus half of the oxygen that the mine should I take it or into it there is nothing to worry about, I will give you I will explain how In any compound, as much total The more positive the charge the greater the total charge it is negative okay only then the compound The total charge above is zero because The more there is plus and the more there is negative, the more there is -1 will PSV-1 become zero or The total plot is as much as you want it will become zero, okay just remember this That'll do the job, just look at this here it is written and here it is written You don't know that sodium oxide is present in it Which is the per oxide and which is the super oxide? You don't even know which oxide it is Let's take it, it's zero, we're okay in this case Sir, okay then what do you do with oxygen? Find it out sir, how will you find it out its oxidation number plus its oxidation The number i equal to 0 will be zero Let us assume the oxidation number to be x I took it x I know about sodium yes sir sodium Do you know the address of the combined state you mentioned? it was that there would be a float yes so it's okay Brother how much will be the sodium float of one sodium will go to + 2 its oxidation number plus its Oxidation number is equal to how much ana hai If it was said to be zero then the total charge of the ion was deducted The total charge of the ion is equal to how much ana is it zero so what if x = -2 comes out yes sir so this It was discovered that sodium oxide is -2 that this is sodium oxide Let's talk about it then brother, I don't know about it Let's assume x has two oxygen atoms so it will be 2x one oxygen becomes x then two oxygen it has become 2x, is there anything worth mentioning No, sodium floats in combined state. if this happens then two's plus two becomes 0 then 2x how much did it come -2 one how much did it come -1 if Oxidation state of oxygen-1 came to what is that it is per oxide so what is this hey that is sodium key oxide similarly you tell me this two I am giving you which hydrogen which is the oxide and which is the hydrogen bond Oxides You can now do it yes One hydrogen molecule is equal to two how much will it be What if x = -2? Yes, then it is an oxide. A hightone float is a float of two, a float of these two I want to find out how much 2x is -2 x how much is the oxide on the -1 sry then you shouldn't have any problem if -2 If it is an oxide then it is -1 If it is an oxide then it is If we get minus half then that is super oxide Find out the same in super oxide too oxygen has another oxygen Chlorides You only have to read two, one of2 and an o2 Find out f2 by placing x in it like this Fluorine can have -1, its If you find out, you will get + 2 for fluorine -1 is always in combined state If you find it out, you will find it here The float will come here, if the float comes then oxygen will come just take a little care of me There is no problem in my opinion Correct is this some general You must know about halides like ion is halide ion okay halide is ions will always be -1 cyanide will be -1 Carbonate will have -2, sulfate will have -2 what will happen on n that is -1 will happen no2 on -1 phosphate ion will be negative no3 This will be -1 over s minus 2. Total neutral is neutral In nitrosonium ion when attached to a metal if it happens then it will have + 1 and what would be the s hey that is neutral it happens if you know If there is any oxidation number then calculate it anytime You will not face any kind of problem in doing this Now you won't face any problem with anyone Can you calculate the oxidation number sir Give an example like this, see Man take you find out nitrogen in hno3 So let's keep its x, there is a nitrogen, so x Kept hydrogen in combined state one oxygen floats -2 three If we add -6 of oxygen then we get zero x = p5 i.e. nitrogen will be in pf Another example hso4 I want to find it, keep one one hydrogen float two float one of oxygen is -2 and of oxygen is -8 then what will be the x T e plus s will be ok next so4 negative x an oxygen mite variable of -8 -2 then what will be the tip of one no3 negative -2 of one and -6 of one = -1 x what will be that is plus 5 c2o 42 will be negative whenever there is any ion This charge will be equal to the Na ion It was like you were writing zero, you were writing zero I was thinking there was a might on it so I put a minus I wrote it was myve then I wrote minus I wrote might if it is there then I will write a minus, find it out If you want to do it then one oxygen will become 2x -2 Mine equal to jitna charge is 2 x is 6 x is plus 3 so one carbon has a plus 3 here you do it mno4 aa in negative Of manganese in m27 ka s2 72 negative ka ka kar quickly Quick Its X is a minuscule variable of oxygen of minus equal to as much charge sir plus from Come I took 2x and took one oxygen minus to minus 14 e 0 because there is no charge If it was not an ion, it would have carried a charge of one How much did x come from p to y manganese Here also in PSE there are 2 oxygen -2 of one oxygen is equal to -1 of 7. Whatever the charge is, how much is 2x 12 pa x how much has come that is six has come how much six is ok You have learned how to calculate oxidation number took There is also another way, let's say this way You are stuck somewhere and you feel No friend, I can't do it I don't remember any rule, man friend, is it okay if we don't remember the rule You will not be able to solve the question at all wrong you are any Joe Peacock for Kovalenko Volant Bond An electronegative atom would be labeled -1 The less electronegative pe + will be the higher value Look, this will be double instead of single, so more Electronegative Pe-2 Less electronegative way + 2 this will be triple So the more electronegative they are -3 the less Electronegative way P3 finish is ok Like sir is taking example h it's a single kovley bond yes it's less If it is electronegative then it has more charge Electronegative P-1 is found out No oxidation number of both sir, someone else Please give an example co2 here is the double kovalenko valent bond for more electronegative pe-2 less pe plot similar here also there is double bund more electronegative pay-2 less pay plot its Oxidation number total -2 its total -2 its p 4 its p f plot here plot What will be the total here, that is PF It will happen sir if there is one more example You will definitely like it ccl4 is more electronegative then -1 pV more electronegative -1 pv more is electronegative -1 pw more ele nitive What will be the total of -1 + 1 carbon Surf will be +F and how much will each S be that will become -1 so this will also become something You have become an example, never forget any formula go ahead you can do it like this also let's say somewhere there is a coordinate bond now coordinate What is a bond and what is it not Everybody knows in which both of them The electron is given by only one atom, so both electrons give to the same atom ok the one who gives is called a donor This is called Apter, see this simple What is Collette Bund, both are one Electrons are donated and sharing takes place what is in butt coat codominate bundle Both of them donate one electron each and Does the other person accept the giver? What is the donor called who receives the donation? Acceptor, in such a case the oxidation number how to calculate If the donor atom is less electronegative or the same is electronegative and the other is either is peacock electronegative or bean If it is electronegative then the donor is p plus two I repeat Apter P-2 Donor either be less electronegative or same be electronegative as compared to other To Donor P Plusto Apter P-2 Example I am doing both first donor less electronegative giving an example am like look at this Look at this simple Kovalenko, this peacock electronegative is pe -1 is pe pv Simple Colon Bond is more on -1 on this now let's look at this this is a Coordinate bond is donor less The scepter more is electronegative If the donor is electronegative then the plate Apter Pay-2 Similar here also donor less Aptar Mor is electronegative electronegative so it has -2 on it What will be the total amount on plus two sulphur? 2 pv pv ps will come in plenty Good but this peacock is here also on oxygen electronegative or less electronegative Oxygen is more electronegative than it is less electronegative okay oxidation of all I have written down the number, there is another example. in na2 s23 which is also called hypo in this Coordinate bond between sulfur and sulfur it occurs This can also be written as o negative a positive It's not a big deal let's talk about it I'll talk about it more electronegative has -1 less p p double the bond is more electronegative in -2 ply single bond is more pe -1 less pe Now let's talk about this bond There is a giver and a taker for both electronegativities are the same because both Both are sulphur, both are successful if both are used Electronegativity will be same for donor and The electronegativities of the acceptors will be the same Even then how much will be the donor's bill + 2 more On receptor -2 You are seeing how much total is on it + 6 how much has come above it -2 a sulphur The oxidation number of one is +6 and that of the other is -2 but if someone asks Average Oxidation number of sulfur average is ok Its individual + 6 is its individual -2 is the average how to find the first six -2 of the other is divided by 2 because there are only two It is sulphur, okay how much will come, that is too If it comes then if the average is asked then both I will write ka+t but if an individual asks then I will write its + 6 and its -2 ok okay son but so plus minus and If all three are zero then when is the plus side plus minus and Zero is not like this brother only has a mive Always if the donor is more electronegative and apter is less electronegative then you get This is how to ignore coordinate bonds You have to act as if you are there There is no coordinate bond, it's okay Like Sir, what kind of examples of daily life hey you don't keep messaging her How are you, talk to me, who am I to you I will eat it once, just send me hi hello I haven't eaten anything since morning I thought I will eat it when I get your reply So I have been hungry since childhood, right? Yes, all of them She sees your messages but you She keeps ignoring you and doesn't reply It does the same thing here as well if the donor is more electronegative If the app is less then we will act like this that there is no coordinate bond there sir yes sir here is the example of h n s n and c there's a triple bond in the middle but of them two are simple covalent bonds and the third one is this is a coordinate bund this is a coordinate bund When calculating the oxidation number, you need to consider ok you should ignore this bond because the donor is more electronegative apter which is less electronegative If it is there then tell me sir then tell me because of this bond This is more electronegative than this -1 on this I am talking about these two bands on Pinterest In this simple collet band hai then lace Electronegative p plate more electronegative p minus and ignore it have to do Ignore, you get some feelings of your own after seeing this it is coming absolutely absolutely it is coming You should also come, tell me everyone What is the oxidation number of hydrogen The float of nitrogen became -1 -2 -3 and Its plot is ok, total charge is also positive The total charge is also minus 3, okay if HC happens if A happens then do a So tell me whose oxidation number should be found out Tell me quickly whose h should be taken out Take out the head of c or n of all three Remove it in simple way Kovalenko c and n in this pe more pe -3 less Pay+ 3 hey this is how we will do hydrogen o [ __ ] [ __ ] [ __ ] [ __ ] [ __ ] my glasses broke Oh God when will the salary come and when will it be added You are looking at these glasses and asking questions only glasses broken Come join me, I have some glasses too No it is different sir you are seeing what is happening The teachers are that hey friend hey join me Friend, take a look and accept it No I can't see anything yes no you are not My glasses broke and I don't know where they fell someone felt It seems poverty has arrived Tell me, 000 rupees worth of glasses are broken Now I am forced to put the 10000 rupee note I will have to, I am compelled, I am compelled, I am compelled let's get started okay what will happen here also t e float and this what will happen t is minus v okay right Did I did not, this line is not correct, my to float from the mortar Should minus ok now let's move on there are some such cases, son, in which you are ok in which what you have to do is that You must know this structure without knowing the structure if you If you do it directly then your answer will be wrong Like sulphur is the maximum of sulphur The oxidation state is +6 is without knowing its structure if you You will do this without knowing its structure If you do this then you will get +8 of sulphur here Maximum amount of sulphur is not possible The oxidation state is plus six Similarly chromium also has +6 here but if you do it without knowing the structure Here it will be + 10 which is possible no it's ok so that's why their You should know the structures which you can use inof Nick, you will study chemistry but I will also Now let me tell you the question that you asked I will give it, something will come out of these No It will come now do it, if you want you can do it now double kovle Bund More Pe-2 Less Pe Plat More Pe-2 Less Pay Plot Single Cowley Bond More Pay Mive Less Pay Plv Single Coln Bond More Pay How much is the quantity of sulphur? 2 P2 + 1 pv how much did you get + s came similarly cr5 Whenever there is a difference between oxygen and oxygen It is single bonded but it has oxide linkage They say it is per oxide or not but oxide or not or oxygen or Single Bund in the middle of will be now again Between brother metal and more electronegative In my my pv my pv my pv but here But it is a double bund so there is might and plot in it How much is the total on this 2 4 5 6 chromium kaya aaye tip k3 it is also like that You should know the structure which I am telling you Nobody else other than these will come, okay? Then brother it is a metal and is less electronegative this is more electronegative myv pv myv Pv Myv Pv pv myv pv how much has chromium come t e plus f has come, how much has come, p f has come This is a blue coloured compound of CR5 Although it is unstable but it is blue in color It has a compound of butterfly-like shape Structure is the small thing that I also study organic but still I don't know There should be c32 yes carbon one more There are also oxides and that's except co2 If we want to find the oxidation number in c32 Here double covalent bond is more p-1 less p p2 this is a carbon carbon bond whenever An atom formed a bond with its own atom if it was kept then the oxidation number would be zero If it is zero then similarly carbon is also present here here is carbon so this carbon has to do with these two Zero for the Bunds too for these two Bunds For this also zero will be the result, zero will be the result, in this also There is zero here but it is not here on the peacock minus less p p if the individual of carbon If asked, its value is plus two, its value is zero This also has a plot but if asked about the average then Average Oxidation number of Carbon of first is plus two and of second is zero the third's plus two divided by th why Because there are three carbons, how much will it be? 4 So one should also know how to take out the individual and Average also br3 o8 and also got it in neet the question is son is here Look, B has zero address for this Bund because the oxidation numbers of B and B are for zero but here more on minus two less p plat more p might less p plat more p might less p p more pay-2 less p plat more pay-2 less Pay Plat More Pay-2 Less Pay P More Pay-2 Less Pay Plat More Pay-2 Less Pay Plat of this bromine + s of this bromine + 4 And Let this D come and go round and round shut it down just arrived Start recording there start it, recording will not start come on brother first tell me the audio is the video clear did I wear my glasses I too gave I kept the no glasses oh friend get new glasses again will we keep doing this today People can't find a broken one will you continue doing this or not I'm feeling good today let's do it again Start yes yes yes yes yes yes yes a little bit I was lagging behind brother, what should I do bhaiya This is the world, when you work in it Difficulties will definitely come, they are bound to happen this goes to happen everywhere in your life ok hey yes yes yes let's go Come on let's start the class again okay in br3 we found out individual so its + 6 came its + 4 its + 6 This question had come in NEET as well But if you find out the average, how much will it be? 16/3 ok like this h2s 2o 8 h2s2o 8 You will find out both the sulfur What will you find out about the oxidation number? The oxidation number of both the sulphurs will be more pay mew less pay plough more pay mew less Pay Plus2More Pay Mine Less Pay Pw More Pay might less pay plot if its found out anyway If you do it, you will get a PS. Find out this as well. Try it and you will like it Try calculating the average of individual PSS That too will be s because 6 is divided by 6 6 by 6 divided by 6 byte a 246 it is exactly the same as h2so was what is the difference two oxygen places Two sulfurs have come in place of two hydrogens sodium has come in place of two hydrogen Sodium has arrived being four Sulfur has two sulphurs instead of two oxyanions Let's find out the two bonds of this sulfur This sulphur is made with the help of sulphur has formed two bonds with sulfur only Ro here you already know about the peacock -1 Less Pay + 1 More Pay -2 Less Pay + 2 More Pay -2 less pay + 2 so its +f If you find out this also similarly then + 5 This is done, individual has arrived + 5 0 0 + 5 but if you look at the average oxidation number one of sulphur + 5 0 0 p 5 divided by 4 will come 10 times 4 which means 2.5 to 2.5 so Individuals should also know these cases I should also know the average, okay and let's see son hydra hic acid it's not a3 it's hn3 this is hydra joke You should only know the acid structure In these cases, apart from these, not only in these cases In this, nitrogen has formed three bonds If all three are with nitrogen then it is zero Nitrogen has formed three bonds, all three This bond is with hydrogen zero for this bond zero but here But the more electronegative one is -1 the less + 1 individual so its known -1 0 0 But if someone says that the average has to be found Oxidation number of Nitrogen one's row second's row third's -1 divided by 3 -1 divided by 3 will come to -1 by 3 it will come ok Structure of exceptional cases was also asked what is it you can build without structure how calcium oxychloride or It is also called bleaching powder The question is asked that these two What is the oxidation number of chlorine which There are three types of calcium oxy chloride One is made up of the ions of calcium ion and a chloride ion chloride You already know that there is a mine and some ion There is no need to tell, it is next oxy chloride ion oxy chloride ion In which oxygen will have -2 and chlorine will have +2. okay so you know both chlorine It's done, one's -1 is one's + is V sir How did Oxygen P-2 come about? Chlorine P + V How did the one that is more electronegative come about? whatever happens will be negative It will be electronegative and it will be positive fe3 o4 if you look at it individually Its + 2 and both of these + 3 is ok but If we talk about the average On average, we were asked more about individuals It happens but if the average is asked it is ok So one + 2 two + 3 divided by 3 8/3 will come right It seems that the oxidation number of A in f34 It is 8/3, hey brother that is average, average Individual its one plus two plus two 3 What is called an oxidant or oxidants which To others It is an oxidase which harms others it's oxido it's called oxidant similarly reducing agent or What is called a reductant which removes the others reduces itself and is oxidative to others and reduces himself to It is oxido sir example see this h2 + cl2 gives you 2hcl this is row 0 is + 1 is - 1 you see Is hydrogen going from rho to +1 yes is it getting oxidized yes is it chlorine is going from 0 to -1 is it yes If it is reducing then what will happen brother what will it be called it will be called that is Reducing agent and what would it be called oxidant whose Oxidation will be that reducing agent whose the reduction will be oxidant will be ok redox reaction What is the oxidation edge well Age reduction happens, for example you and your It is visible right in front of me, it is ok and I am telling you It is not the case that anybody can be seen in it Meaning in which there will be oxidation as well as reduction Mallika Sharawat ji will also meet Anil Kapoor She is talking to Nana Patekar as well as she is also talking about types of redox reaction is ok types of redox reactions types of The first redox reaction is comination The reaction is evident from the name itself when two We will combine things and make one thing They say combination reaction sir example Here it is mgo2 gives you 2mgo these two things combined to make one thing I've made it, okay, what would you call it? combination reaction now this combination reaction They check whether there is redox or not Here this row is also its row this is + 2 this is -2 Really sir you are right its oxidation has happened and its reduction has taken place then this Combination is a redox reaction, next is Decomposition is the reverse of combination reaction What happens is that one thing breaks into two or make more things like see this edge gives you AG Plus o2 magnesium has been reduced to oxygen what did you do with sorry i want to write this here there was reduction of magnesium and Oxidation of oxygen has happened, one thing is missing If two or more things are being made then There is decomposition and there is redox because one is getting oxidized, the other one Reduction Next What is displacement reaction when No one is mumbling anything, nor anyone else The third person should go and break it, it's okay You should sit in his place to see such a reaction we call it decomposition reaction how-how hey the same thing when it comes to baa and baa exchange happens don't you understand yes when you You have a boyfriend, right? And he has no best friend would be you someone wow If you act, then you are what you are you leave his place and do what is best He is a friend, what would have happened if he got promoted? he becomes my boyfriend yes yes yes Best friend is nothing but a boy friend in It is waiting, it is exactly like this For example, look at this here: Zinc and HCl reaction took place and became zncl2 plus h2 gas in which you are seeing metal which is zinc okay which is zinc what did it do to hydrogen I have done it, I have displayed it, right? by removing the hydrogen from here and throwing it away He kicked me out yes this poor boyfriend happened I used to do chlorine, it was today's date who is it in that is zinc right yes yes yes come on come on come on, everybody is understanding Sir you are saying very relatable things to everyone ok next is dysprosium Oxidation also occurs as well as reduction Oxidation of the same substance also occurs it happens and reduction also happens it's ok what do you say dysprosium Here, the oxygen Look, they are looking at -1, -2 and 0 If oxygen goes from -1 to -2 then its reduction also occurs similarly to oxygen which is -1 if it goes to zero then its Oxidation of the same substance has also occurred Oxidation is what happens to the same substance that is rid it happened ok Is aa which is the reverse of disproportion it is called com proportion com proportionate yes I will write it down Rivers of Dis Propose Com Pronation If I write these as reactants, this If I write the product then it is com proportionate it will happen just keep explaining let's do some questions about oxidation I have asked for S's number in cocl2 sir right now I just said one's float one's -1 one's plus one of -1 because one of these is negative and it is found in the form of negative See next question, which redox? This is a reaction, let's check it p-1 pw-1 pw-1 pw-1 anyway double d There is a composition this came here and this came here The double D composition reaction that takes place is redox does not occur does not occur it is also like that sir this is hydrogen Calcium is here Hydrogen is here Sir this is also a double D composition sir this also there is no redox, okay this is also like this hey kayam has come here ammonium has come here Calcium chloride will be formed and ammonium hydroxide will be formed as ammonium hydroxide is formed a little ammonia h2o It is made of ammonium hydroxide Ammonia broke down, this is also a double D composition it is not the same as it is it will happen again No answer sir please prove it and show me the proof Let us show that S P -1 is P Pv If it happens you will find it out by keeping an account of it then it will float this is zero this is zero its its float in this human its has it been reduced at all Correct Has the zinc been oxidized? Of course it is a redox reaction oxidation state of chromium cr5 I got through NEET 2000-14 just now 10-15 minutes ago we had a drink Those compounds were listed below Tell me whose oxidation is plus ph of sulphur plus c will come here, try it Even if plus f comes on y, plus f will also come on y Plus F will come on Y also, two gone from Aa 6 will come, PS will come here too, how many are there Bhai one two three with plus f then you get the number Had to tell off compound, three will come, one by one, one by one y plus s hayy p will it come or not This is a question that came in AI PMD Oxidation state of sulfur in these anaes Try and see if the order is being followed I will find out by keeping x plus 4 will come let's try keeping this as well 2 a mi 8 = -2 2 x6 will come out i.e. and 2x - 12 = -2 so 2x 10 will come That means if 5 comes then s2o 42 negative will be the highest less then so3 2 negative then h26 ya option Number B is B is B is B is B is the oxidation number of the underlying atoms Tell me, is the identification okay? x p 3 will come, this is also correct, this is not the answer So this is the answer but still if you If you want to find out then do x = 1/2 of s of two plot then how much will x come -2 will come -1 is written So that's wrong which reaction is not a redox reaction Which is not a redox reaction tell me who is not this is an oxidation There is a reduction happening and then this double again It is a displacement reaction which is also double Displacement reaction occurs and at any time Redox reaction does not occur to solve There was no need, okay sir this single This is a displacement reaction, instead this instead it will be this Sir here also is it in S5 or in zero reduction has happened it is in zero or it is on pwalk Sir this is also redox this is also redox so this is not the answer this is not the answer because this is also redox this is also redox it's not redox whichever double It is displacement, not redox would have been the following reaction is the metal displacement reaction displacement also and whose metal is getting displaced Aluminium is being displaced here Chromium is here, displacement is here Displacement of Chromium is happening So is chromium a metal? Absolutely correct sir this is the answer sir whose displacement is happening is hydrogen This is displacement but not metal It is a displacement reaction of non-metal displacement is taking place or There is no displacement or de composition This is one thing breaking and becoming two or three things It is also de composition, one thing breaks into two things is being made ok correct statement not statement I have to speak, I have to speak structure Please tell me the correct structure of tri bromo Octa Oxide that nobody is right Friend, this could have been correct, you should have written it like this now That's right, it was made a while ago don't use your mind, just did it hey mums queen who is the one The redox reaction is the reaction of h24 with a Sir, there are these doublets in acid and base. There is displacement sir it comes here hey it comes here is it done or not na2 A4 and 22o The double displacement that occurs is never redox does not happen sir this happened in atmosphere o3 from o2 good o2 to o3 making all the atoms total in these too The oxidation number will be zero, in this also the total It also does not happen that the oxidation number will come to zero I can sir Nitrogen Oxides Form From Nitrogen and oxygen by lightning good nitrogen and oxygen combine to form nitrogen oxide Sir, you are making it, many of them can be made Here is which one do you want to make, make any one Whatever you wish, I will make it number 2 I Made it no2 is this redox yes zero it went from zero to minus yes sir this it is redox sir this is the answer epore of water This is a physical change by the way The reactants are the same and the products are the same That's not a redox reaction anyway redox reaction then chemical reaction would have been Is Which of the following Dysprosium is given just below reduction so this is disp pon here this is + 6 to + went into 4 Oxidation is also happening and reduction yes sir this is also there here in one m p 7 6 in P4 not sir this is just Reduction is happening, this cannot be possible this also reduction m this also reduction of a whose oxidation is taking place is the bean of oxygen Oxidation of cheese should be the same thing there should be a reduction of this it is not there and this So the reverse is dispo com pronunciation is p make p with p the answer is also not a and option B is any yes or A and B Hot Concentrated Sulfuric Acid A It is a moderately strong oxidative agent Which reaction is Oxy Behavior she is not showing good i.e. what reaction sulfuric acid to other substances it is oxidizing sir it is going from 0 to +4 its oxidation means this is oxidant this cannot be possible, it is double The displacement reaction is double Displacement reaction is a redox reaction There would be no oxidation of anyone Someone's reduction happens, this is the answer sir Oxidation is also taking place in this Sulfuric acid is Oxidative decay is becoming sulfuric Acid is So this is also like an oxidant here even here here also I am not doing this No, there is no redox reaction here It is about oxidants, where will the ox come from? No reaction at all is next Read this year's latest question It was a bit debatable because somewhere There was a printing mistake in the paper It was there but whatever it is is fine here It is a redox reaction, mention its type here let's check h2o2 -1 to -2 and zero Its reduction has also happened, its oxidation has also happened It happened to be a dysprosium here comes calcium here they vedium vedium If I go away then there is a pain somewhere my friend I would also say that there should be displacement Displacement many what is here one thing is breaking and two things are remaining, this is one Decomposition is the decomposition of a function Coming to reality was what it should have been That was supposed to be the combustion reaction of methane Combustion is taking place, CO2 and water is being produced but because no option is matching we're forced to keep it to that is combination reaction then It is a compulsion, meaning the answer should be 2 3 41 is there any option 2 3 41 here it is 2 3 Fav is ok What is the best description given below? what will happen to bromine The description would be bromine or zero. it's here in the mine it's here in the float then oxidation of bromine has also occurred Reduction has also occurred, oxidation has also occurred. Option Number A option number A Which of the following compounds contains metal has zero oxidation state of it so right now I found out, TIPS came here But it is not metal, they have made no metal He said it is not metal, this is any metal I had told you its xs would be neutral If 5 = 0 then what will be the result of one or zero In this the oxidation state of A is zero yes this jamun came in 20224 oy a variety we have posed the question of okay so that you No problem of any kind came Sulphate reacts differently with iodine and bromine Sulphate iodine is reacting in this manner converts it into iodide okay thio sulfate bromine to bromide converts it into sulphate itself gets converted okay here's a There is average in plus two, I am writing average Here it is available in 2.5 or 6 see both is reducing iodine as well reducing bromine as well that is, there is an oxidant here as well It is working like this here too Butt is acting like an oxidant The products are different for both of them It is going from plot to p 2.5 i.e. that itself just a little bit of an oxidant it's working like this here it's plus two is going from to ps that means very More Oxidative stress of oxidative agent Acts as a reducing agent Younger rids bromine under goss reduction iodine under gos this is wrong io sulphate Undergo oxidation by bromine and reduction By iodine this is also wrong in both the worlds Oxidation is happening here as well of sulfate and here also bromine is a Strong and Oxidants yes because it is an oxidant so bromine If it is a strong and oxidizing agent then more to this It is absolutely correct to do oxidative EE because he is taking it straight from two to six and this will take it to only 2 to 2.5 If so, bromine is a strong oxidant yes this is correct section number c is good Question it is a good question Oxidation in the following compound is Extraction of iodine is done by extracting state x Let's keep one oxygen -2 of 6 -12 of one hydrogen + 1 of four + 4 this becomes eight, eight goes over there and becomes minus -8 going there it will become +8 sen has come here Option Number C is ok yes the question is done, the mistake has come again I just went there Quen ha the oxidation number of phosphorus in pyro phosphoric acid h2 p27 pyro this is what will happen na do h3 po4 add I'll take the h2o out of them I will give it to you yes this is what will happen okay now take it out It has 2x one oxygen -2 7 -1 t 2x 12 is it yes what x is it p 6 is it I made the structure wrong h4 p27 is coming h4 p2 because by taking two h3 po4, out of which I had to find h2 so 2 came to 10 so one How much did you get son? 5 p 5 Look what is pyrophosphoric acid take phosphoric acid What do two phosphoric acids mean? Gaya h6 p28 take the h2o out of it what does pyro mean It happens, heat it, remove the water and it's done h4 p27 Sir, we have learnt this from Inergonic It is a good thing that I learned in chemistry I also did the same Which of the following is an example? The dis propo shone reaction of this pronation Example hey it is going from ps to ps 4 Oxidation is also taking place in Reduction is also taking place here, so this is from is going to P4 this can't happen from to 2 there is only reduction from to to Reduction in P4 is oxidation of sulphur I agree but we want the same thing oxidation of and reduction of the same thing Oxidation of manganese is required here, isn't it? Only reduction of manganese is happening This is a little practical physical chemistry The question has been given with the combination of B Do you read anything No, there is a chemical reaction going on over there It has been asked who will have what type of reaction hydrolysis Reduction, oxidation and double D composition The main compound has to be mentioned here plus 3 going from one to zero And this is a double D composition, go here here came from minus two to zero in and this is so hydrolysis add water yes he is reacting with her hydrolysis is this is option number b this is a four ha a ka four is actually hydrolysis of water B's one is really reacting with The main compound is getting reduced plus 3 going to zero is c of th c Is oxidation happening? Yes sir, sulfur. Going from might to zero and d cut d Kat Double D Composition told me dull d compose good que is a great question which question has come in JE mains In the reaction hydrogen is replaced by an oxidizing agent is it working well or the other one Oxygen is reducing itself Let's see, there is talk about it Sir iodine reduction is happening here Is did you give it a dose of oxido or not there is c pv in hai also pv mine y y also no in sulphur-2 to 2ps that is it has It was oxidised by hydr per oxide any oxidizing agent that oxidizes another Now we will talk about the n factor calculation of or which is also called valency factor He says it's okay it's nothing friend The number of offs within a reaction electrons are lost or missing what are they called what are n factors are called n factors number of electrons Lost and Found what is the molecule called that is a it is called factor okay sir okay sir this How do we find out a How to find out the factors carefully See, suppose there is a such that from a x b a thing is formed this is the reactant and this is formed Yours In this only the oxidation number of a changed and b has not changed a The oxidation number here is p here plus q The oxidation number has not changed It happens that here also there is plus aa, here also there is plus aa so How to find out n factor whether it is a has undergone oxidation or reduction has occurred It doesn't matter how will they find it out Tell me to keep it out of the mode first Atoms But Molecule hough oxidation number change whose oxidation number is changing How many atoms are there in a molecule? How many atoms are there in a molecule? First The oxidation number of the first minus the second in the bud the oxidation number will be less than a factor If this oxidation has happened then it will come That is the number of electrons lost if a key If there has been a reduction then this number will come off the molecule is placed carefully on the electron deck Listen, tell me whose oxidation number has changed Sir A is inside a molecule of A. How many atoms are there? You have to write atoms only, right? whose oxidation number changed by how much atoms sir in a good mode first of all What is the oxidation number p minus later what is its oxidation number T here the answer will be A factor sir Give me an example of this, this question Here, A A is oxygen from P might oxygen here is also -2 but it becomes mn2 what only and only If you want to find out mn4 accordingly then tell me mn1 mode previous oxidation number minus The latter's oxidation number is five. means to mno4 If oxidation was happening then it would be okay to say loss do one more like this cr2 o7 2 negative gives you cr3 We have to find the positive n factor Its here is in +6 oxygen is here only otherwise it doesn't matter Find out the factor and tell me whose Oxygen is changing the oxidation number If it is not there here then there is no question of oxygen It is not possible to talk about Chromium How many atoms of chromium are there? Two mode previous oxidation number minus any The charge on the ion of a single atom It is a single atom, yes its ions have this charge this is its oxidation number or it's thr I will multiply r by two how much will it be will go 6 ok Second Case See If Meni Particle Oxydol cull than n factor total explaining ill t summation of a factor I am an oxido son, I am explaining it to you for a minute Time take what i wrote if only one single molecule inside a molecule has two things got oxidized or it became three it became four it became five it became six It's been eight okay so how is it a factor we will take out whichever has undergone oxidation okay by adding the A factor of all of them The A factor of all those which have undergone oxidation Not by adding sir, four of the same molecule If all four species were reduced then For all those who have undergone reduction, Sir Example by Adding Factors Y paris Its name is oxalate Ferrous oxalate is ferrous fe2 positive oxalate is c24 negative it converts fe3 became positive and in co2 you have to change it a factor is asked a vector is asked attention Listen, first remove iron plus two carbon by keeping the x of Take out P3 and oxygen will come. Might I put the carbon x here and take it out? P4 and its Might there be three types of particles here is a a a a carbon a oxygen So there was no change here or there There was no change in the oxygen Neither oxidation nor reduction has occurred from Fe2 The oxidation process done in P3 from P3 to P4 If oxidation is done then how is the total n factor I will first take out A, then carbon I will take them out and then add both of them to A Tell me how many A Haven Modes have been oxidized before number minus the subsequent oxidation number Plus how many atoms of carbon are there Two modes: Oxidation number of first minus second the oxidation number of is okay so son this one this will happen it will come out to be Three is ok There was no change in oxygen here either, son minus two there is also minus u so its not will keep third case of a molecule Oxidation of something inside reduction of some things happened If so, how will you find the N factor? Find the factor of those which have undergone oxidation Take minus those who have reduction their n Take out the factor and then minus it Minus two conditions and apply this for zero It should not come equal to zero, it is not like that that this is eight this is 8 so 8 - 8 you write zero no brother i can't do this no We can do this because if the n factor is zero If it goes then equivalent mass no, suppose this is 8, this is 6, then 8 - 6 You can write 2, there is no problem, it is 6 this is 8, even though 6 - 8 mode is engaged then also two You can write it, there is no problem, it is sane This is 12, you can write it down, no problem this is 13 this is 10 will you write three someone There is no problem but don't do this, this is my favorite yes this is f 5 - 5 don't write zero, this is answer Five will come, answer five will come, this is seven If there is seven then do not write 7 - 7 zeros in this case I'm ok 7 have to write answer for example example this r When kclo3 is heated then it is formed There is no change in kc2 from c+5 -1 reduction of oxygen -2 to 0 Oxidation is done right its reduction its oxidation is the same some of the molecules have been oxidized If some reduction has happened then n factor first of the oxidation take oxygen three into zero goes 6 aa will go to reduction this will also come ch sir this is also ch this also there is 6 minus 6 zeros, don't write A have to write factor total t e s ok both are ok They are different and are one, then write 7 minutes 6 i the last one i dis Prep How N Factors in Reaction Resistance remove the feces of di propo know the beans Oxidation of species and reduction of the same First take out the A factor of the oxidation one Then multiply both the reduction ones Do this and add both below two below multiply both by two above and see this like below h22 gives you h2o And there has also been a reduction of oxygen in it Well, oxidation has also occurred, which is a total factor how to remove it First remove the A factor, tell me about oxidation brother How many atoms of oxygen are there in one molecule the two modes of oxidation number of the first one minus The next one will come two, this one is like this Find out the reduction factor, how much oxygen Atoms have two modes, the first being the oxidation number Minus the subsequent oxidation number sir this also two will bring n factor oxidation into n factor reduction divided by total 4 by foe comes out to be one comes out to beacon is ok There was a printing mistake in the last slide Hey, you tell me what happened son, I will fix it I will take it if this also comes as a six this also comes as a six If you come then do not write answer zero, write answer six I have to write yes if it was 8 or it was si then write the answer to Sir I have not read anything from A yet you can start it, you can start it absolutely If you do not start then further how will you reach NF oxidation was written instead of NF total where is it written this is what you are talking about no good here Thank you son for telling me what is the change in oxidation number of the Carbon in the following change in oxidation Change in oxidation number is to be found out that's what happens that's a factor anyway can you extract carbon x p 4 e 0 then There will be a carbon accumulating on mine 4 y also ka myv ch ka -4 so This option number became 1 minus 2 B option number B is ok is the balancing of redox reactions when You see someone balancing Keep the redox reaction in mind is this possible it is absolutely possible It is absolutely possible, let's see how to do it let me tell you in a simple way ok hey look at this a p B C I don't know if a stomat coat will come before them. coming and coming, that is called balancing Finding the N Factor Take the result of factor A and the resulting sto metric The coefficient of B is similar to that of an factor B What will be the sto metric cuff If its factor is F then write F on Y If factor two comes then write two here okay its n factor is its sto The metric is the coefficient which is the n factor of this its sto sham qfit is the first step so cleared seconds Balance All Accept Hydrogen and Oxygen Hydrogen Balance everything except oxygen Okay, we'll do it sir, and look here, there are five atoms If there is one then we'll have to do five here too I will multiply it, someone will tell me talk oxygen How to balance D h2o deficiency Atoms of Jan are consumed in the product side If there are atoms of oxygen then where is it less How few are there on the product side there were 10 here There is sen three less so product side put 32o in it ok no sir one more Let's take an example and do the reactant side The product contains only four oxygen atoms There are 12 oxygen atoms on one side and four here. If there are 12 here, then there are less eight here, so what about here put it in, you put 8 h2o, the matter is over Correct we will balance oxygen d h2o to The deficit side is fine if either medium is it acidic or neutral If you have hydrogen then do you know how to balance it? Is d) Positive ion to deficit side Where there is less hydrogen, you get hydrogen ions Put a po there let's say on the reactant side Six hydrogens on the product side 15 where is hydrogen less reactant side how much less is it in 15 my 6 na so 9h patv on Put it in but sir if it becomes medium basic then what will you do when the medium becomes basic To balance the hydrogen h2o to the deficit side Where there is less hydrogen, add H2O there and equal number of o negative ions to opposite Sir please explain side to opposite side Let's take an example and accept it absolutely medium basic okay here 18 hydrogen Atoms there are 14 hydrogen atoms tell me where it is less here it is less here How much is less sir, it is less, it is 14 and 18 sir Four is less where there is less hydrogen there is A Put it in and take 42 pcs there is less hydrogen there put and equal number of ne a tojit side and same net income on opposite side I should just know these steps and keep in mind in you can do calculation ok like Look at this mno4 negative plus iodide plus h positive gives you mn2 positive ps aa2 ps h2o have to balance First of all write the oxidation number you will read what they have written it was written it has been reduced to p to plt I have gone its oxidation has happened from myo to ji In I will take out its N factor, that is its store It is Shamet Cfit, should I find its N factor? its stoma is official take out its n I just taught you the factor of M A atoms How many are the first mode oxidation The number minus the next one will come only five here But I will also take out the N factor, it is an atom The oxidation number of the former minus the latter Its N factor is its sto shamate The official who is its N factor is its sto shamet official hai sir first step ho What happened next was to balance all the atoms do accept hydrogen and oxygen there there's one here's a balance iodine here's five There are two here, the balance is done, yes sir it is done now The medium is acidic because a positive ion I have given you basic oxygen too So balance has to be done in the same way by adding h2 There are four oxygen atoms here and one there. There were four here, there is one here, three oxygen levels are low put 32o here 1 h2o earlier it was three You have entered four now hydrogen balance Do H positive end in acidic medium We have to put eight hydrogens here one hydrogen is seven h positive add One was already there, this is done sir, this balancing it is not very correct I said why sir because here in If it is not in integer then it is in integer Multiply by two to convert Make it two as soon as everyone multiplies by two We will do this in your equation which was 5 times That will be converted to F, rest all will be converted to 2 Low balance will be multiplied by all two Done go ahead son one more will do this please this Kari is ok Its beta reduction has occurred, its oxidation has occurred Its A factor happened first Nikalu is an A from a to a two it went to F a came One at to th it went na aa which is its n factor is its value which is its n factor That's its balance all atoms accept Hydrogen and Oxygen Balance All Atoms Accept Hydrogen and Oxygen right now I will also get the basics done, son. There is a If there is MA then there is one here and 5 there then this But the balance is now oxygen balance we will do it here there are four here there is one son here are four one here means put 32o here it becomes 42 will go because you had an H2 earlier put three more here a hydrogen here one hydrogen so sir here 7 amp divide I will put this in my account and it will be done Balance forward Grow Me After Balancing a Redox reaction i struggled a lot May god give such struggle to everyone in life as you did hey do it a little quickly We also need to balance the electrons, sir, son number of electrons lost and number of If the electron gains are same then they will cancel out If I am going to get out anyway, then why do it why should And here it is in y plus s here y plus 3 is in here y plus f The A factor which will come in this will be its tomato he is an official take out a factor 2 mud 6 my 3 1 mud 3 my son it has come 6 it has come which is its in factor is moles which is its in The factor is its moles, the balance is Atoms Accept Hydrogen and Oxygen Chromium becomes four times the balance nitrogen Here the balance is fixed, now balance the oxygen How much oxygen is there here? 7 to 14 and 12 26 Oxygen there's 18 and there's 19 oxygen atoms 26 If I add 19 to what is left, it will be 8 will go The balance becomes 16 and one whenever the balance We do Smallett in the Possible Integer They write, you see whose table is 2 6 16 46 8 I can go to Sir or Sir Two's table If you can go then divide it by two like hey you are divided by two If you do this then the equation will become 2 to 2 divide it Just now some kids were saying Sir Basic Get the medium one done, I will also get the basic medium one done I will give it to you, I will even get it disproportionated so that both things will happen just one thing Taking care of the dysprosium hey add them at the end and write it down friend Suppose one came in 3 f2 and the other came in 5 f2 3 f2 Write it down as 5 f2 Write it down as 8 f2 What is the big deal in that but they are different I have to write, I have to keep only one thing in mind Dysprosium moment look this cl2 ps negative gives you negative p cl3 negative p h2o medium It's basic, it's already clear, okay Never mind it went from zero to -1 pf In The reduction happened by going from zero to -1 and on going from zero to 5 Oxidation Sir In Dysprosium not a matter of There is nothing to worry about for now Just write it twice, that's fine Its n factor will come out to be Its sto shamate is oxidation The official who will get its A factor will be the value Let's take a reduction, it's a store of it If Shamet is the official then first A factor I take out the atoms of those that are oxidized How many are the two modes of oxidation? Number minus son is the later one right sir 10 aa 10 very correct similary its n factor How many atoms are there in Nikalu reduction? Two Mode zero mode first oxidation number minus the latter oxidation number sir these two What did you say son, whatever comes of this will come Its stamina is cuff which will be its a factor Ttv its stock is ok balance it If the oxidation atoms are four then I made them four lia chlorine atoms reduction There should be 20 atoms so I made it 20 Karya Balance L Atoms Accept Hydrogen And how will the oxygen balance be here? there is one here 12 and 12 more Where there is less, there is less oxygen put that many h2 there put 122 Now hydrogen balance has to be done carefully Please see, P 24 and N 25 are hydrogen. how many are there just here Wherever there is less hydrogen, I will put h2o there How much less is 25 and 2 23 less so here 23 I will put h2o 1 h2o was there earlier 23 you Put the same number of negative ions there I will put it here oh negative ion was 23 you Now write it down properly Just sir this is 2 cl2 and how much is this 10 cl2 sir 12 cl2 is done absolutely Sir this 12 h2o and this 24 h2o are cancelled will be out and only 12 h2o will be left here you are absolutely right you sir this is 24h negative yes gives you 20cl negative yes 4 cl3 negative yes and 12 h2o yes is the largest integer in the table I come with 12 24 24 and 12 yes sir four k All integers in the table start from four divide by 3 cl2 6h neg 5cl neg 1 clo3 neg + 3h 2o is it clear son is it clear how did you decide that cl2 to clo3 For the negative one you can do as you wish Taking the value for an oxidation is equivalent to a reduction So I accept that it is your wish and say yes You could assume that these four atoms were oxidation So I multiplied it by four There were a total of 20 chlorine atoms So then the reduction that we did is n factor If reduction is taken out then the atoms of reduction I will balance the oxidation, so I have removed it Atom Balance of Oxidation I will do ok there is another example let's take another example yes you do it br2+ negative gives you [music] do br2 you have the whole page Ro went to -1 and went to plus va sir Dysprosium Take it out, I assume it is oxidation-causing You can accept this reduction as any So far, anyone can believe that The factor will come and this remove the stop, the atom is the first one Oxidation number minus the subsequent oxidation Sir two came, two very good this one too Removal of two previous oxidations Number Minus The latter oxidation number sir this is also bye Chance two came, bias two came, what should I do then Brother, its N factor is its value which is its factor its moles are four atoms I will balance the oxidative ones by four If atoms are reduced then here also there are four Write down the balance of atoms accept Hydrogen and Oxygen, that's done sir Balance your oxygen, do oxygen Balance here and one here, five oxygen went and there is only one oxygen here or 5 h2o put balance two hydrogen sir There's a hydrogen 10 and a hydrogen 11 11 only There is less hydrogen in two places where There is less hydrogen, put h2o on the opposite side I have same number of negative ions here na h2 10 it will happen because earlier it was negative here here girl it is negative right you entered it write 10 Combine the two and make two and two more B 52 will be cancelled out by this 102 becoming 52 It will go absolutely right K negative 4B negative 4 b come negative plus 5 be A2 Nothing went wrong my gut feeling is telling me that something Mess I don't see what's wrong Where Pe mess then because look what's wrong two hydrogens already The six is to come then it will be alright six anna here replaces si 52 42 well there 42 no here 42 okay okay okay okay fo If it gets cancelled then you will be saved It's ok now son, something went wrong step Now let us see which are the biggest integers I can go to Sir Two's table, everybody. can it be there in the table then it should be there will go 2 br2 and 5h negative gives you 2br negative 2br negative p 3 h2o Who is saying there is no charge balance brother There is no charge balance The previous one is balanced yes balanced yes I do this, I feel it is not working It's too much, I would have done it again Am I do it again check this first is it because in the process of finding a mistake Sometimes what happens is that you search for I can't find where it happened so now relax I had told you so much whenever I If it is to be disposed, you should write it down twice. jotted down Sir, its N factor had come two sir. N factor also came two on last page had we na which is its n factor is its sto Shamet is a cuff and its Factor of four atoms Reduction Oxidation of four atoms up to then there will be no problem, that is absolute Right now do the oxygen balance from here We will do it slowly, there is only one oxygen here and there are four oxygen here and five oxygen there When oxygen levels are low we add it h2o sir there is less oxygen here there were five here and one if it was here then it will be added here 4 A2 42 ok The hydrogen balance is now balanced will do four hydrogen sorry at hydrogen here one here nine Hydrogen here is only and only two Hydrogen is ok sir there is less hydrogen here Wherever there is less hydrogen, we will add h2o there no you were here you were here 7 h2o how many should I add 7 h2o now there was 1 h2o earlier so add what are you doing I went and here there was 7 negative ions one o ago You added seven, it's done, now we will do it son 22 can you write 4 br2 hmm this 4 h2o like 8 h2o went here four Escape and will go to 4ohm P how are you doing 4h Friend, I should have written eight aa eight hai this eight eight tha eight oxygen atoms eight The oxygen atoms are balanced and the hydrogen is now The balance is Son is now balanced we can divide it by this sir can we divide everything into fours If it is divisible by four then br2 P 4 oh2 now it's okay I will divide by four and get one will go two will come one will come one will come And one will come to see that oxygen is balanced it is balanced see hydrogen it is balanced Bromine is balanced, see the balance is B now It's absolutely correct son, the charge is also correct, everything is fine It is coming ok it's ok now If there is any problem then tell me Give it in any one of the previous steps A mistake might have happened, then the same step again Problem created, now charge balance also Here the total charge is -2, here also the total charge is -2 Correct charge, you do not have to pay balance charge The balance will come in the end, it said the charge Do balance, do not do any balancing yourself there is balance on this my my might it is done on this It has become totally mighty, is there any charge for this no, there is no charge for this in total Minus here and there Main let's do some questions on these You will get this question in J Mains in 2023 We have to tell what is x which is its n factor it will have a stomach coat and will I use it I can find out the factor taking out the f is going to zero Just think how many iodine molecules are there in one molecule Atoms Mud the first oxidation number minus the second If two iodines are given on the bulb then 5 iodine 2 10 aa You can also balance it with iodine atoms could, but there are two iodine atoms here If it is 12 then how many will be there on y it will be 10 only 10 it would have been like that Absolute Right Absolute right down nice this dysprosium Let's go next what is k4 written as oxidant working and making mno4 negative mno2 is making m23 is making pow tell me how many electrons will be transferred factor is asked Write the ionic form of mno4 once formed have mno4 2 negative once again is this making it son mno2 once making this son mn2 o3 and once again this mn2 is making positive a factor has been asked, we will find out A factor E means number of electrons transferred That is the A factor here, this is the Is there a factor in going from SE to PS? The first oxidation of manganese atoms will happen Minus the latter one arrived Here too a Factor 7 minus 4 comes out to be 3 aa gone factor Y Plus 3 aa Gaya is a factor here too if code 7 minus 5 comes then what will happen 6435 5 1 3 4 5 is there anyone 1 3 4 5 here it is 1 3 4 5 Option number C There is a reaction below, balance it is do Brother, whatever A factor comes will be its sto is the Shamet coefficient which is its n factor Its storm will come, its N factor has to come Six means it has to come in place of b here Six Its n factor is anna plus f to plus ja it is two two two which means we have to come to the same place let me write two and see Chromate Six Sulphate The ions balance out the rest Hydrogen 2a was two then how much should be 2a will four bb kitna tha six to six sulphate and they now turn into oxygen We will balance something, it is chromium balance sulfur balance oxygen balance will do 2 to 14 14 and 18 32 oxygen how many atoms are there here 24 aa is less add aa2 I'll give you hydrogen here 16 first check if it is divided by an integer then it doesn't become 2 6 16 4 6 and 8 sir two If it gets divided by two then make it one Divide this by 8 Now try it with fit A, B and C have been asked 8 8 option number B is a redox reaction, correct it Coffee of the Reactant for the Balance If it is correct then I want to tell you what will you do Its n factor is and its moles are n factor is to come pa its n factor is to come is two its n factor is from its mole its a factor is its moles two a so two a 10 carbon to 10 carbon oxygen balance do 8 and 20 Take 28 m n is two let pa a po 16 y two pa 16 I am doing it in front of you too Bhai read the next hot con, this is done friend queen is done In acidic medium h2o converts dichromate ion to converts your cr5 account into cr5 Oxidation state is asked sir plus f is it did it a while ago When we heated and concentrated chlorine gas When it reacts with A then oxidation takes place What is the change in number if AO is hot end This is a question of concentrated energy then s goes negative and cl3 goes negative If it is hot and concentrated energ nic this is a question, I kept it here like that If this were cold and diluted then here but it comes negative it comes negative he asked What change will come in the oxidation number if it becomes zero From Mov & Row to P 5 0 to -1 0 to P Here Option Number b is b b b Any compound has three atoms If the oxidation of an element a b c number a is two of b is wife of a is son of a what is + 2 of b + 5 and -2 of c so what The formula might be out some time soon We told you about the oxidation number The total charge deducted in the calculation whatever happens, that much is the total of naayan charge should be cut and the beans of the naayan should be cut And Anyato I am writing here the total charge deducted I will write the total charge here anaato then ion itself Who will be the bani katai and how much should it be for 2a will be 1 of a + 2 of 2 + 4 of 2b how much Will be done 10 how much is 6 s 12 sorry 6 is the value of 6 s No sir this cannot happen, total charge deducted Ion and Nayan are not same as + 6 2 B be 10 of Went 8c -1 it is done yes that is + 16 yes sir that is correct it is absolutely c option number B one person is saying sir plus s will be plus 5 Calculating Beta Oxidation Number So learn this, the chapter is about to end Do not calculate the oxidation number yet learn one oxygen's -2 three's -6 e -1 so x how much did you get 6-1 = p 5 ok no problem Small details happen let's talk further son range of After this we will just talk about the oxidation state. This is also a small topic, its a After that one more small topic will remain that is Redox hydration is then chapter finish Your first fix is range of oxidation State like that the minimum value of any element Oxidation state or maximum oxidation We should know what the state will be okay especially if we talk we Must know P block Elements in the Third Group Onward sorry third period onwards I will show you the periodic This is the first period in the table Hydrogen and helium are the second period I'm talking about everything from lithium to neon hmm p block first of all this is p block And third period onward I am talking about them I am all of these, all of these, all of these are okay Understood from here to here I'm talking about okay so their range of Oxidation State Minimum Oxidation State from to maximum oxidation state How many shows will they do, what is their range equal to The oxidation state of n will be from minus 8 to upto n where n is the number of Valence electron number of valence electrons okay There are 13 groups from 13 to 18 how are valence electrons assigned to groups will take out Group number -10 Group number -10 means 13 How many valence electrons are there in each group There will be 13 - 10 3 14 in the group 14 - 10 4 15 In group 15 - 10 5 16 16 - 10 in group 6 17 in group I am like this and also in 18 group What Sir, CR5 plus S will come, I think it will come Plus S will come son, you are absolutely right you did it today we have okay good range of oxidation Now I know how to remove the status Now from the range of oxidation states, our What will be the benefit if any element is used in your in maximum oxidation state Have you understood the meaning of maximum the most? Whenever a chemical is in an oxidation state If the reaction itself decreases, it may increase I can't do it at maximum already If it is at maximum then never take your oxygen I can't increase my status, I will only decrease it If you reduce yourself then others will also reduce it will work sir it will work of oxidant Like if someone is in minimum oxidation state will already be in minimum oxidation state The chemical reaction cannot go below that will always come out above this if it What will happen if Oxydo himself comes up If oxido reduces the other then how? reducing will work How much work an agent does will do the third and the last one is suppose is in an intermediate oxidation state There is no minimum or maximum, no minimum in between if any oxidation state is showing then This means this will be oxidative, will reduce the other It will work as a reducing agent will reduce to others acts as an oxidative easing agent will do Intermediate How will it act if it is in oxidation state reducing agent will do and oxidant Name the oxide which is the reducing agent of not working like Maximum oxidation of carbon state plus f is here in plus f it starts with P it is in PF plus f is plus four has plus si it is in plus pho but how do you know The maximum of all these is this much right now Just tell me friend, just now I told you the range of Oxidation State Range of Os Dation State It has four valence electrons so -4 to + 4 can show if there are seven of them then -1 to p If its five then it can show from -3 to + 5 can show if it has six then -2 to + If I can do 6 shows then I will do the maximum here It is written by friend maximum maximum Maximum that is what is written, that is what is written now Tell me who works as a reducing agent can't work like reducing eight doing this means reducing the other person oxido itself means will it go up I can't go up sir it can't go could already be in maximum oxidation state hey i can't go to p5 sir go here can go from + 4 to + 5 + 6 + 7 this can also go is + 4 to + 5 it can also go + 4 to + 6 OK that which is dysprosium will it be in or maximum see At maximum it can reduce or increase I cannot, if it is at minimum then I can increase it can't do less okay or you can do this also You can say that Dispo does the same shows that will be in intermediate will I will write oxidoxy like this, it is B right? Write the range of oxidation state I am a fool to me whatever is a fool can happen That cannot happen because of disproportion There may be those without it here who is 3 who is 5 who is not It is possible sir, this cannot happen, look at this it can decrease it can also increase it may decrease it may increase it may also decrease It is possible Now ask this question yourself, who will dispo show will do it among the following this is also the same who dysprosium it is in zero it is in zero then in myeve you can also go to the can also go to the So this can definitely be dispo shown sir Did fluorine die? Fluorine too Fluorine and period are in this group and is most electronegative Whenever the element forms a bond with someone Always my oxidation number will be in In compounds there can always be + 1 + 2 + 3 it can't happen, it can't ever happen Dysprosium [music] because it is always the most electronegative If only negative oxidation state will show all three can do this yes this is the biggest question today it itself do which can undergo dysprosium ch can not show dispo just done Fluorine and do it yourself does not go under right now what the same beans for bromine Question for chlorine also Come let's talk about our small topic last t is titres i think half n We will finish the chapter in a moment What happens in titration and carefully Listen, there is an experimental setup which contains any substance k you concentration molarity normality weight Or find out moles etc. How to find out the right sub is taken in a burette This burette inside and one here inside the beaker or Carries inside the conical flask specially conical flask is ok Its to us I don't know that it is unknown, we need to find out I have to do it and I would have known about it how much is it molar or is it normal I know the thing, I don't know it, okay Now this chemical will open the noose below When both of them will react to each other Both will react and at equivalence point gram let me name it a I will name it as per the number of grams The number of reactions that would have been equivalent to a The same gram equivalent of v was reacted okay x point p we have to knob This should be done, it should be stopped as per law so this should be the but equivalence point After that comes the end point there the knob is turned off happens because we don’t know whether We don't know if the equivalence point has arrived The moving equivalence point has arrived so we have what is kept here just after the indicator class point there is only one The indicator will regain its color immediately after the first drop It changes, the color change means hey brother you reached x point quickly If you turn it off, it's practically the end We get to know the point in butt reality you should know the eleventh point okay this we say in titres titres The first one is that it is acid base titration At one place there will be acid, at another place there will be base, then there At the end point, the number of grams equivalent The same number of grams of acid will react Will they react to equivalent bases? I have four formulas for gram equivalent yes sir mass I taught you mole concept by equivalent mass or volume into Normality or volume into molarity n factor or moles in n factor so the same I am rewriting the four formulas here. hoon that is wait by equivalent wet volume into normality volume into molarity in n factor or moles in n factor if you have this The volume which is taken in milliliters I will tell you the milligram equivalent I will tell you the milligram equivalent, okay Sir tell me which formula will be used in that The mass is given depending on the question If yes then this volume has been given normality then This volume molarity is given, so this If you have moles then it's fine like this Look, the question came only in 2024 is 50 mA of 5 molar oxalic acid it it happens leak Acid is required to neutralise 25 ml of AO ok you have to tell AO 50 AA In the solution first I whatever amount comes in na5aa solution then it I will multiply it by two because it is 50 I want to tell you in AA, tell me in 50 AA if it is then I will multiply it by two, okay It doesn't matter how many grams are equivalent oxalic acid will react to the same extent Gram Equivalent yes I have given the molarity sir it will be applied here volume into molarity in n factor volume into molarity into n factor ox acid will give two a positive ion then a factor There are two, volume has been given here also I will find the molarity and then you will get the n factor I know the molecule of a base is a negative Will you give me the morality that you have got? it is 2 * 2 4 this 2 molar has come Correct has the molarity come to you to take out the mass can you find out if the molarity has arrived And if you want to remove the mass, you can remove it can not take it out ho, how much molarity have you given us this mass To find out molar mass 40 volume 50 Is it 4 grams it went fine What will happen in redox titration? Titration is just a redox reaction That means one will get oxidized to another Reduction will happen as a reducing agent one will work It will act as an oxidant, most of them The first reading we have to do is in the redox titration potassium dichromate a what will you call it That is Ox Titres Potassium Dye Chromate is a very good oxidant In which acidic medium and which Write the names of both the indicators used A factor has to be found out first the oxidation number of the first minus the second out to be So the acidic solution of potassium dichromate What is the n factor in medium, that is it is six okay sir potassium dye If chromate is an oxidant then others oxido ka yes to whom Oxido Fusion Those written in capital letters mean Small letters have no meaning converts paras to perique converts stuns into stenic converts sulfite to sulfate Is h2s into sulphur and also so2 iodide in sulfate is converted to iodine oxalate is called oxalate c2o 42 negative to co2 and nitrite to Nitrates Potassium dichromate in acidic medium I will turn ferrous into ferric and stuns it convert sulfite to sulfate in stannic so2 in sulfur to iodide in sulfate iodine converts oxalate into co2 and Nitrate is converted into nitrate by itself. it will get converted automatically will always go with cr3 positive and in h2o Like I will show you by giving an example You should get something written like this This is how you are asked to complete the reaction Do it although it is a part of organic but When I learned it, I said I would tell you am potassium dichromate acidic medium I do a fusion show that means Ferrous The variety converts itself into ferric always converts to cr3 positive and h2o Did you learn how to write a product? Now you can balance it perfectly Its n factor was six its sto shmate kafit its n factor one will come its sto Shamet Official Balance L'Atoms Accept Hydrogen and oxygen have now become oxygen balance it, there are seven oxygen 72o 14 hydrogen is 14 a pow see brother How much time did it take to do another one like this Get it done then I will accept you, I will go with everyone First you have to write its product then you have to balance it Potassium dichromate in acidic medium shows fusion i.e. nitrite is converted into N is the conversion of nitrite to nitrate it always converts itself cr3 becomes positive and converts into water Its A factor was its sto metry coat Its factor will be three to get two will come and its Stot four is chromium four ho Nitrogen will be present go to oxygen balance oxygen 14 and 12 26 oxyanions 18 or 19 oxygen is low here Balance Now if you want to divide it by u then do it Give and your wish but balance is done balance is ok there is a person sir come here in basic medium come here come to the camera hey nothing i I want to hug you I want to hug you wants to put I just want to give you some Hug me, time will pass, don't worry ever Correct it happens sometimes the topic is not named If I had read it, sometimes I would have felt sorry dacre is very good oxidant in which sa Medium written hey let's do nothing How much volume of potassium do we need The chromate that will react is moles of Observe Ferrous Sulphate in Fusion converts ferrous to ferric It does nothing to sulfates. It does nothing. Potassium dichromate does nothing convert sulfites to sulfate Will give but does nothing to sulfate acidic Convert paragraphs to text in Medium It gives the type which gets converted automatically always cr3 positive and h2 nothing to do friend while asking questions Number of grams of equivalent potassium dye Same number of grams of chromate equivalent Sulphate of ferrous ion is not written, it is not reacted There is sulphate here also, there is sulphate here also If sulphate is not reacting then this It makes no sense for me to write If I want to remove volume then what should I apply formula volume into molarity and its n factor is given by its moles So moles * n factor is grams The formulas for equivalents can be any Of the four I just told you about We have to find out the molar volume and the n factor Six moles are three, what will be the n factor going from ferrous to ferric will there be one sir We will get the answer as 1/p2 i.e. 10/2 that is 5 litres will come 5 liter what is oxidation number of f2 positive wow wow wow wow wow any single mono atom can be converted into ion if it is in the form of then the charge for it its oxidation number is the same as that of Two is positive, its one, its three It is positive, it also has three positive 14 and 12 26 how much is 18 and this should have been aa aa means y will become 16 okay son how many moles at positive which will react with 5 liters of two molar Then The number of grams of potassium dichromate or equal to the dichromate ion Gram Ict A Po Kens How much formula will you use for its grams? volume in molarity in factor volume in Molarity in this its molas ask me in at it will it go into this, do you know how to find the factor yes Sir two will come, two two you are absolutely right Two out of two got cancelled Answer 30 has come Answer 5 * 6 30 Increase Normality Solution Read this question yourself k4 will do just fine too Oxidant is basic even in acidic condition even in neutral when medium is acidic then a4 will be there and mn2 will be in positive Convert will it be in basic me or neutral medium Somewhere it is written Basic, Weekly Basic is written Or if it is written neutrally, the matter is the same, then this will convert to mno2 And if I have used the word somewhere else Strong basic then it will convert mno4 u said I am repeating if it is basic somewhere Even if medium is written it will be in mno2 Even if it is written neutral it will be in mno2 Unless you use the word strong Basic is fine, even if it is written basic, it is the same Even if the word is used it is still the same Only if there is a strong basic then it will happen otherwise no here what will be the a factor from p If it is going from to the plot then the n factor is pa Here it is going from P to P4 n factor is three son here p to If it is going into PS then its factor is one We know how to extract the A factor correctly The main reactions we need to read are I want to study in acidic medium, what kind of study I want to study in acidic medium mno4 in acidic medium it is self indicator Is there a need to insert any indicator from outside There is no act Ace Strong oxidant should I use this word again Meaning you will have to say yes or no in the chat box please reply Fusion Ferrous to Ferric Stanus to Sthenic in h2s to sulfur to sulfite to sulfate The A factor in me is always the same yes it acts as an oxidant so are taught to take it out we have okay okay okay if it is written softly alkaline then that is it is feeeeeeee basic You are asked the value of A in this question. The question is what is n, the number of electrons gay saray so a factor asked absolutely correct Is this a factor that the plot is going from P to P There will be oxidation of A atoms in one mode the number minus the next one will be five sir yes five If it comes, write it down D&F is also pretty much covered. I know it's covered How many moles of oxalate ice would be required when One mole of mno4 will be negative and the same number of grams equivalent of mno4 negative equal to Gram Equivalent Of Oxalate which ion formula will be used to find moles in a factor a factor f is its a medium in What will be the factor to calculate its moles Oxalate ion is converted into CO2 P3 This will give rise to the factor of carbon atoms two modes first oxidation number Minus after the answer has come 2 ba f sorry 5 Batuu 5 Batuu Ba Number C Is this one and this one the same question? read this one and this one please read 2 ml off kmno4 of unknown molarity good a4 key I have given volume 2 mA 2 AA molarity we don't know x I should accept it, yes I should accept it sir it is required to Reach the End Point when Titans are 20 ml of oxalic acid The volume of the product is 20 ml Its molarity is t molar, its molarity is more than yours kmno4 has been asked then the same for both Gram These lines will be equivalent again and again There is no need to write, I am reading This is the reason I am writing to you What is the amount of grams needed Volume into the molarity you need to extract into a factor which was five here also volume into molarity into a factor Removed two in the previous question also it was two it went to two it went to four 4 in 2 what is 8 x 8 molar 8 molar Correct hai ict mass mn4 ka half of its molecular mass is good ect mass molar mass is half of tell me how mnso4 has been converted Do you know what mass is equal to? Mole mass by a factor so this shows that a factor two came now tell me the type of mn4 should I convert that to a factor of two? will I get m23 by doing it in it will come that y is p or y is p No sir this factor will not come, try it. take answer this is not what to do in mno2 will come from at nikla A Atoms One Mode First Oxidation number minus the latter yes sir really two came so this is the answer sir mnO2 m2 is a good question How many moles of kmno4 are required so that mole can react with ferrous oxalate good number of moles of kmno4 asked When a mole reacts with whom Same again with ferrous oxalate here it is k4 Ferrous in Acidic Medium oxalate see ferrous also in ferric converts oxalate to co2 It converts and it itself knows it m and t positive and in water then its gram equivalent and its We will make grams equivalent to gram but grams To make it the same I need to multiply its n factor by You should know this + this from 2 + this from 3 + Oxidation of iron and carbon has also occurred Oxidation has taken place. Today we read that When two things are oxidized then N How to find the factor total? First, calculate its total. factor then its n factor by adding both Give The A factor is the N factor of carbon. Is this it? Three has come now do it both of you brothers K grams of beans moles into a factor hai na ka The factor is 5, then here also moles in a factor 3 then how many moles of k4 are there in 3 parts It is a very important question in the exam has come many times Do this question in your homework and answer it forest coming When the reaction occurs potassium permanganate potassium iodide and potassium Permanganate acts as an oxidant yes it does It converts iodide into dian Gives basic medium in acidic medium Oxidation of iodide to iodate in State A manganese is divided into plus two to P no it goes from P to plus two this is wrong it's right region falls Iodine is a very good oxidizing agent for whom for these Meaning of those written in capital letters small letters have no meaning Iodine converts stannous to stannic it does it, it will not react, reaction This is what will happen to thio sulphate containing thio sulphate It is very important in tetragonal converts it into tetra thio nate converts it hey rc night this is r s night ko rc converts it to net converts sulf sulfite to sulphate gives Others are oxidative convert thio sulphate to tetra thio Does it do that or does thio sulphate come like this also in exam it is na2 s23 which is called hypo let's say hypo na3 52 it happens i have done that D No 52 Write how much volume of molar A2 will be required good volume asked is molarity What is the molarity of iodine which will react with mole of hypo that is hypo this is special It is written that the number of grams equivalent Same number of grams of iodine equivalent What formula would be needed for hypo The volume to be drawn into molarity A factor is two for this moles into a How do I find out factor A? I haven't figured it out convert sulphate to tetrayonate Here the oxidation state is 2.5 calculated today in na2 s46 and here if you have any then please take it out How many atoms of factor sulphur are there? Two modes of The oxidation number of the former minus the latter I will multiply half and half by two one will come the answer came volume in liters 5 batu t e 2 Liter 2 Liter iodine is a very good oxidant Likewise, iodide is a very good reducing he is an agent and will reduce others and himself what would it be oxido oxido a factor v will come sir who will he will reduce, today only I read that mno4 In acidic medium iodide turns into iodine it used to go into mn2 positive The dye was lying today Iodide Iodine in Chromate Acidic Medium I used to become S3 positive and H2 positive myself It would have ended today itself but again like this just wrote it down With this, son, this is our chapter for today. The finish is fine There is something wrong with the last one, son. let's check it Son, tell me your mistake, I will correct it I will take 2.5 annas here 5 divided by 2 2.5 OK If there is calculation then do that much yourself you guys can Correct hey thank you for you guys because day is in And it's a day out, isn't it easy to take classes everyday? There is no work brother it's a tough call this is me I agree, it is easy to get batches online Consistency is maintained in online classes It's tough to do, you're expecting to be the first Are you attached to the class or in the middle? Those shows have happened and are continuing that you are very committed to your goal per is fine and the one who is committed towards his goal He will be successful only if he is committed to What are the chances of being obviously successful? it's too much ok Let's start with a small topic of this chapter there is electrode potential but that is me I will do it in electro chemistry I will do one in electro chemistry The child said normality today The topic of the solution chapter is in the solution It will be done, okay let's meet Thanks for giving to you in the next class as your time thank you kids
