Chapter 4, Problem 4.117P

Interpretation Introduction

Interpretation:

The mass percentage of ${\text{KClO}}_3$ in the $0.950\text{g}$ mixture of ${\text{KClO}}_3$ and $\text{KCl}$ is to be calculated.

Concept introduction:

The redox reaction can be classified into three types depending upon the number of reactants and products as follows:

1. Combination redox reaction

2. Decomposition redox reaction

3. Displacement redox reactions

Combination redox reactions are the reactions in which two or more reactants combine to form a single product. In displacement redox reactions, substances on both sides of the equation remain the same but the atoms exchange places in order to form the product while in decomposition reaction, one compound decompose to form one or more product.
