Chapter 19, Problem 55E

Interpretation Introduction

Interpretation: The balanced equation to describe the reduction of ${\text{H}}_2{\text{SeO}}_{\text{4}}$ by ${\text{SO}}_2$ is to be stated.

Concept introduction: Loss of oxygen is known as reduction.

In the reduction reaction of ${\text{H}}_2{\text{SeO}}_{\text{4}}$ by ${\text{SO}}_2$, the molecule ${\text{SO}}_2$ acts as reducing agent, whereas ${\text{H}}_2{\text{SeO}}_{\text{4}}$ acts as an oxidizing agent.

To determine: The balanced equation that describes the reduction of ${\text{H}}_2{\text{SeO}}_{\text{4}}$ by ${\text{SO}}_2$.
