Chapter 16, Problem 6ST

Interpretation Introduction

Interpretation:

The ionization constant for lactic acid when the hydrogen ion concentration of a $0.100M{\text{HC}}_{\text{3}}{\text{H}}_{\text{5}}{\text{O}}_{\text{3}}$ solution is $0.0038M$ is to be calculated.

Concept introduction:

The ionization for a weak acid is always in equilibrium. The ionization equilibrium constant is denoted by $K_{\text{i}}$. The weak acid ionizes in a very small amount, so, the value of $K_{\text{i}}$ is very small.
