Chapter 18, Problem 18.75QP

Interpretation Introduction

Interpretation: As the potential of the anode in an electrochemical cell is increased, the halogen among ${\text{Cl}}_2$ and ${\text{Br}}_2$, which will form first is to be stated.

Concept introduction: The salts obtained from the evaporation of sea water can be a source of halogens, principally ${\text{Cl}}_2$ and ${\text{Br}}_2$, through the electrolysis of the molten alkali metal halides.

To determine: Among ${\text{Cl}}_2$ and ${\text{Br}}_2$, the halogen which will form first as the potential of the anode in an electrochemical cell is increased.
