Step 1

Oxidation state or oxidation number of an atom refers to the charge on that atom that it would have been carried if the compound is composed only of the ions.

Redox reactions are those chemical reactions in which the transfer of electrons takes place among the species undergoing redox reactions. This means that these reactions are accompanied by change in the oxidation number of the molecule or the ions by loss or gain of electrons by that species. If a chemical species gains electrons during a redox chemical reaction then it is said to be reduced while if it loose electrons it is said to be oxidized in the redox reaction.

Step 2

Since every redox reaction is made up of two half reactions where one is the oxidation half reaction which shows the species that looses electrons  and the other is the reduction half reaction which is used to depict the reaction in which the chemical species gains electrons .

Step 3

The given redox reacti...
