Identify the species that undergoes oxidation, the species that undergoes reduction, the oxidizing agent, and the reducing agent in each of the reactions of the previous problem.

For auction. E aluminum is losing electrons to form aluminum three. Positive it undergoes oxidation. Hence it will act as reducing Agent Vera's for sent our four positive it is gaining electrons to form said Are it undergoes reduction. Hence it will act as oxidizing agent What option? B in this reaction and always losing electrons to form and or too negative it undergoes oxidation. Acting as reducing agent Bye for silver Eiji Positive is gaining electron to form Eiji, it undergoes reduction. Therefore, acting as oxidizing agent for option C In this mg is losing electrons to form mg which two it undergoes oxidation Hence act as reducing agent by S I 03 to negative is gaining electrons to form aside it undergoes reduction. Hence it is acting as oxidizing Agent for option d m n 02 is losing electron to form Eman or four Negative. It is an oxidizing agent while CNN or three negative is gaining electrons to form chlorine Negative, it undergoes reduction, hence acting as oxidizing Agent

Oxidation is lost off. Electron vile reduction is gain off. Electron oxidizing agent is the species that undergoes reduction. Violet oxidize the other species present in the reaction. The reducing agent is the species that undergoes oxidation, but it reduces the other species during the course off. Reaction for option A The species that undergo oxidation is S 03 too negative. The species that undergoes reduction is see you. Which two for option B oxidation is undergone by Eman which two by reduction is gone by or do option C oxidation by EJ two on reduction by a notary negative optioned. The oxidation is undergone by aluminum by reduction by chromium.

In problem six identified species oxidized and produced in the following electron transfer reaction. So this question is taken from the topic. Oxidation reduction, a Redox reaction. So this is the equation that is given in the question. Okay, So the concept behind this question is the oxidation reduction reaction. So basically, oxidation means laws off electrons or in terms off the oxidation number, we can define us. Oxidation is the increase in oxidation number. So increasing oxidation number is called the oxidation. So basically, oxidation number is the charge assigned often element when present in combined state with other atoms, or has in its iron form, according to some set off rule. And that will our call the oxidation number rules. Okay, Now we can define as the reduction, so reduction means gain off electrons or in terms off the oxidation number decrees in oxidation numbers. So basically decrease in oxidation number we can define as the reduction. Okay, so now coming to the question that is the equation which is given in the question. So, first off, all we find out the oxidation number off each element in this equation. Okay, so the oxidation number off this magnesium which is in free form, that is zero. According to oxidation number rule, the oxidation number of cobalt plus ion is plus to the oxidation number off magnesium plus Tau ion is plus two and the oxidation number off combined in this case is zero. Okay, so that means this we can see that the magnetism is getting oxidized because the oxidation number off magnesium is increased. So this species is oxidized, or we can say oxidation can take place in this case because and we can see that the oxidation numbers increase and this cobalt is reduced. So we can say that this is the reduce, or we can say that the reduction can take place in this situation. So that means in this equation the mechanism is oxidized and cobalt Oh, plus ion is reduced. Now, as the reaction proceed, the electron transfer the electron transferred from McNish in tow, able to place I in because as we can see that this magnesium, those two electrons So this equation is called the oxidation half reaction. And when this cabal took plus ion against these, the electron that can form cobalt So on adding the above equation, we get magnesium plus COBOL two. Plus I own that conform magnesium plus combined. So this is the equation on Erding. So the two electrons are cancel out each other. So this division is basically the oxidation half reaction, because lost two electrons are lost in this equation, and this is called the reduction half reaction. And this on adding the equation destruction is called the paradox reaction. A Redox reaction is the direction in which both oxidation and reduction can take place. So overall, we can say that this is the equation. So finally we can say that as the reaction proceeds, electrons are transfer from magnesium toe cobalt. Oh, plus I own and ah, this oxidized species is magnesium, so oxidized species is magnesia, and the reduced species is cobalt two plus ions. So this is our final answer.

We will look at a real reaction and determined which one is oxidized. Which one is reduced? And what about the oxidizing agent in reducing agent things like that? So we have this equation Nigerian monoxide to react with oxygen in water, producing the nitrates I am and hydrogen ion. So first, let's look at the exhibition. Stay. Ah, the element. So for nitrogen, the nitrogen in nitrogen monoxide Ah is positive. Two because oxygen is negative. Two. Okay. And then we're gonna look at the right side. It turns to, uh, nitrate ion so it will be positive by oxygen's unite the tip too. So, um, three oxygen ion is negative. Six soul nitrogen will be positive by and now we're gonna look at the oxygen in the element oxidation. Stay is zero. And now it becomes negative to here, so ah, against the electron and hydrogen is not changed. It's still positive. One. The oxygen in nitrogen monoxide in water. Um, also do not change the our station stage. So we have a nitrogen change from positive to two. Positive. Fine. That's a losing the electron. So it's losing electron, so it it will be Leo. Remember? We used the, uh, freeze to, uh, to memorize the two hard reactions. Leo is Lucy electron is become oxidation. Girl is gaining. Electron become reduction. So this is losing electron. Uh, and then the Erdogan, the oxygen change it to negative two from zero. That's gaining electrons. So it's reduction. Okay, so, uh, uh, this written. So we'll be answered. We'll be able to answer the first question. Which one is oxidized? So, um, oxidized, we'll have a oxidation reaction. So which means, uh, this one is oxidized. Okay, All stands for oxidation. So nitrogen monoxide is oxidized. Or to be more specific, is the nitrogen in Nigerian monoxide is oxidized. Okay, second question is which one is reduced? The one that is reduced is the one that, uh, has a reduction reaction. So it's the It's a one week girl girl. Miss gaining electrons reduction. So is the oxygen is reduced. The oxygen in oxygen molecule is reduced. Yeah. Next question is asking which one is the oxidizing agent? The oxidizing agent is, uh, to oxidize others, and the other one is oxidized and then is reduced by the other one. So the oxidizing agent is the one that is to oxidize others, but it itself is reduced. So the oxygen is reduced for this oxygen. And the next question is which one is reducing agents? The reducing agent is to reduce others, so oxygen is reduced. So it's reduced. Bye. Uh, nitrogen monoxide. So nitrogen monoxide is a reducing agent. Okay, which is Cell is oxidized. So to be more specific, is the nitrogen in nitrogen monoxide? Yes. The reducing agent. Last question is not really the last question. The next question is which one gains electron gaining electron or and then the exhibitions debut decrease. So you see oxygen. It is from zero to negative two. So oxygen is the gains electron. The last question is, which one lose electrons, so losing electron oxidation state will increase. So you see nitrogen. It changed from positive to positive five. So nitrogen in nitrogen monoxide loses the electron. Yeah, that's all for this question.
