Chapter 19, Problem 19.94QP

(a)

Interpretation Introduction

Interpretation:

The possible electrode reactions and overall reactions of electrolysis of given electrolytes are should be written.

Concept introduction:

Electrolytic Cell:

The device, which is used to convert the electrical energy into chemical energy, is known as electrolytic cell and this type of cell are works under the principle of electrolysis.

If the cell potential is positive, that cell reaction takes place spontaneously and if it is negative, the cell reaction does not take place.

Electrolysis molten salt:

The decomposition of chemical by passing through an aqueous solution of ions is known as electrolysis.

Half-cell reaction:

In electrochemical cells, the redox reaction take placed by two half reactions, one is oxidation and it occurs anode and another one is reductions it occurs at cathode.

In oxidation the species lost its electron and in cathode the species are gained electrons in cell reaction.
