Chapter 21, Problem 31PS

(a)

Interpretation Introduction

Interpretation:

The balanced chemical equation of electrolysis of $\text{NaCl}$ has to be written.

Concept introduction:

• Balanced chemical equation of a reaction is written according to law of conservation of mass.
• Stoichiometry of a chemical reaction is the relation between reactants and products of the reaction and it is represented by the coefficients used for the reactants and products involved in the chemical equation.

(b)

Interpretation Introduction

Interpretation:

The ratio of the product $\text{NaOH}$ and ${\text{Cl}}_{\text{2}}$ produced in the given reaction should be determined.

Concept introduction:

Sodium chloride is also known as brine. The electrolysis of sodium chloride is an industrial process. The products obtained from the electrolysis are sodium hydroxide and chlorine. It is one of the most important methods to produce chlorine.
