Chapter 15, Problem 15.74AQAP

Interpretation Introduction

(a)

Interpretation:

An anode in the given reaction should be determined.

Concept Introduction:

Electrolytic cell uses an electric current to derive a nonspontaneous oxidation-reduction reaction and process in known as electrolysis. In oxidation-reduction reaction, the transfer of electrons occurs from one reactant to another reactant.

The reactant which loses electrons during the reaction is oxidized whereas the reactant which gains electrons during the reaction is reduced.

An electrode where oxidation that is increase in oxidation number takes place is known as anode.

An electrode where reduction that is decrease in oxidation number takes place is known as cathode.

A reaction which is either oxidation or reduction reaction component of redox reaction is known as half-reaction. It is obtained by considering the oxidation states changes of the reactant and product in the redox reaction.
