Chapter 19, Problem 39E

Interpretation Introduction

Interpretation: The mole ratio of lead (II) to lead (IV) in ${\text{Pb}}_{\text{3}}{\text{O}}_{\text{4}}$ is to be calculated.

Concept introduction: Oxidation state of pure elements is zero. In a chemical reaction, if oxidation state of an atom increases, then it is oxidation whereas reduction is characterized by decrease in oxidation state.

To determine: The mole ratio of lead (II) to lead (IV) in ${\text{Pb}}_{\text{3}}{\text{O}}_{\text{4}}$.
