Answer 1

Answer:sms under go oxidation because it reduce it's electron and according to defination the element which redux it's electron is called oxidiesed element

Explanation:

Answer 2

Answer: a. $Sn^{2+}$ is undergoing oxidation

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

For the given reaction:

$Sn^{2+}+2Fe^{3+}\rightarrow Sn^{4+}+2Fe^{2+}$

On reactant side:

Oxidation state of iron = +3

Oxidation state of tin = +2

On product side:

Oxidation state of iron = +2

Oxidation state of tin = +4

The oxidation state of iron reduces from +3 to +2, it is getting reduced. Thus, it is getting reduced and it undergoes reduction reaction.

The oxidation state of tin increases from +2 to +4. Thus, it is getting oxidized and it undergoes oxidation reaction.
