Chapter 16, Problem 16.49QP

Interpretation Introduction

Interpretation: The value of $K_{\text{a}}$ for the ionization reaction of lactic acid is to be calculated.

Concept introduction: The equilibrium constant $\left(K_{\text{a}}\right)$ of an acid dissociation reaction depends on the strength of an acid involved in the reaction. The value of $K_{\text{a}}$ is large for strong acids and small for weak acids.

To determine: The value of $K_{\text{a}}$ for the ionization reaction of lactic acid.
