Chapter 15.2, Problem 22PP

(a)

Interpretation Introduction

Interpretation:

The given half reaction should be balanced in the acidic solution.

Concept Introduction :

A balanced chemical reaction is the reaction having same number of all the constituent atoms on both sides of the reaction arrow.

To balance a half reaction, first the atoms other than hydrogen and oxygen are balanced. After balancing the other atoms, ${\text{H}}_{\text{2}}\text{O}$ molecules are added to balance the number of oxygen atom. In the acidic medium, hydrogen ions ${\text{H}}^{+}$ are added to balance the number of hydrogen ions. After balancing all the atoms, charge is balanced by adding electrons.
