IXRCISE Barreol can also be oxidized to camphor with other oxidizing agents; such as sduum dichromate in acid. Write a balanced equation for this oxidation (0,0 is ...

For the redox reaction $\mathrm{SO}_{4}^{2-}+\mathrm{Ni}^{2+} \rightarrow \mathrm{SO}_{2}+\mathrm{NiO}_{2}$ assign oxidation numbers and use them to identify the element oxidized, the element reduced, the oxidizing agent, and the reducing agent.

In problem 13 40 Redox reaction. So this is the Redox reaction that is given in the question. Assign oxidation number. Identify element oxidized. The element reduced. Oxidizing agent and producing agent. So this question is taken from the topic. Oxidation reduction, a Redox reaction and Redox reaction is that reaction in which both oxidation and reduction can take place. So the concept behind this question is the oxidation reduction oxidizing agent and reducing agent. So, first of all, we try to understand the oxidation. So oxidation is basically the laws off electron. So laws off electrons called oxidation or in or in case off the oxidation number concept, we can say that oxidation means increasing oxidation number and oxidation Number is basically the charge assigned often element when present in the combined state with other item, or has in its iron form, according to some set off rules, and that will are called the oxidation number rules. Now reduction is the gain off electrons or in terms off the oxidation number concept decrees in oxidation number, and the Redox direction is the direction in which both oxidation and reduction can take place. No, we can understand the term oxidizing agent. So oxidizing agent, are those which can oxidize other but itself. Reduce and reducing Agent are those species which can producer there but itself Oxidize. Okay, now coming to the question. That is the Redox reaction which is given in the question. So this is the Redox reaction which is given in the question. Okay, So the oxidation number off this magnets to plus ion is two plus the oxidation number off hydrogen in China tree is plus one. The oxidation number off nitrogen in a Channel three is plus five oxidation. Number off oxygen in a channel three is minus. The oxidation number off hydrogen in H +20 is plus one oxidation number off. Oxygen in H +20 is minus two oxidation number off form agonies in Emma Noto is plus four. The oxidation number off oxygen in Emma Noto is minus two oxidation number off. Nitrogen in N O is plus two. And oxygen is minus two and hydrogen is plus one. Okay, so now we assigned the oxidation number off each element. Now we can see that the oxidation and reduction part so clearly we can see that this manganese so that and Rigo plus Tau tau plus four. And it's oxidation state. So that means increasing oxidation number in this case. So that is known as the oxidation. And this nitrogen that plus five to plus two. So that means decreasing oxidation number. So that is called the production. So here, that is the observation that is called the reducing agent and the reduction that is called the oxidizing agent. Okay, so basically, finally, we can say that as the oxidation number oxidation number off agonies wow, increase from plus two, two, plus four. So it is oxidized and hence aumento plus ion actors reducing region, on the other hand, cool as the oxidation number off nitrogen degrees from plus five, two, plus two. So it is said Toby reduced. And hence I channel three nitric acid actors oxidizing agent. So basically no, we can clearly see that the yeah oxidizing agent, which can oxidized other so oxidation, is basically the increase in oxidation number that is in case off magnets plus two, two plus for that when increase in oxidation number. So that is why this undergoes oxidation and in case off a nitrogen in national three that undergo the reduction because the oxidation number off nitrogen degrees from plus five, two plus two. So that is the reduction case. So now, oxidizing agent, which can oxidize the other. So now I see that this, uh, China tree can act as the oxidizing agent because which can oxidize so basically, this nitric acid a Channel three nitric acid can oxidize to manganese mn two plus ion and itself reduce so itself reduced. So that means this is reduced plus five, two, plus two. So, in case off for reducing agent which can reduce other so this Emmental Plus can act as the reducing agent which can reduce that so clearly this a channel three is reduced. In this case, that is, the nitrogen reduce from plus five two plus two and itself oxidized and Magnus is itself oxidize Eman two plus two plus four so itself oxidize. So that is why this Emmental plus ion can act as the producing region

Sir. For part, a nitrogen is oxidized as it gained oxygen and or to gain electrons so it is reduced. So into east nitrogen. Introducing agent and or two is oxidizing Agent answer for part B. Carbon monoxide is oxidized. Is it gained Oxygen and or two gained electrons. So you taste reduced. So carbon monoxide these reducing agent and or to east oxidizing agent he answer for Parsi, SBC L three is oxidized as it gained oxygen and C l two gained electrons. Yeah, so it tastes reduced. So s B C l three introducing agent and C L two is oxidizing agent answer for party petition Miss Oxidize Is it gained oxygen and let plus to gain electrons so it is reduced. So protection is reducing agent and PV plus two. He's oxidizing, isn't

Hashemi The balanced chemical reaction will be six iron oxide plus or three three. F. E. Two or three in this case All three is the oxidizing oxidizing agent. While F. E. O. Iron oxide is reducing agent. Option B plus brought me to. All right. For schools provide. Sorry it will be 10 raw meat. Yeah. Four. Uh huh. PBR fight romain is oxidizing agent and phosphorus is reducing agent. Yeah, option C. The balance reaction H. two or prove plus two c. 0. two positive plus two H30 positive Leads to formation of four mortar just to clear positive. H202 is oxidizing agent. Where else cobalt is reducing agent, auction D See her 204 to negative plus six chlorine negative plus 14. It's 30. Pososos leads to chromium three positive plus three. Sale too Plus 21. Water chromium oxide is oxidizing agent, chlorine is producing agent. Yeah. Yeah. What can see to see you. F. E. S. Two plus four oxygen. Mhm. Copper sulfide Plus two high iron oxide Plus three cellphone dioxide oxygen oxidizing agent and corporal. Yeah mm reduce engagement afternoon H. Two C. O plus 02 carbon dioxide. Press water. Yeah oxygen is oxidizing agent and H two Ceo is reducing agent last auction auction G. C. three H 8 Plus 502 Leads to three c. 0. two plus four. Water oxygen will be oxidizing agent and C. Three A shape will be producing agent. Mhm

And question # five, it asks you to identify the substance that is oxidized. The substance that is reduced. The oxidizing agent and the reducing agent. The oxidizing agent is always what is reduced and the reducing agent is always what is oxidized. What is oxidized will be the species that has an increase in charge. What is reduced will be the species that has a decrease in charge. If we have nickel, having a two plus charge going to no charge, then it was reduced and it will be the oxidizing agent. If we have chromium going from no charge to two plus, then it was oxidized and it serves as the reducing agent. If we have a species taking on hydrogen atoms any time an organic compound takes on hydrogen atoms it is reduced, it is then the oxidizing agent and hydrogen donating itself will serve as the reducing agent itself being oxidized. So just remember anytime you're adding hydrogen atoms to an organic compound with carbon, hydrogen and oxygen, the compound is being reduced by the hydrogen, and the compound is the oxidizing agent, hydrogen, on the other hand, is being oxidized and it is what is allowing for reduction, so it is the reducing agent.
