Chapter 15, Problem 105E

Interpretation Introduction

Interpretation:

The $K_{\text{a}}$ value of the lactic acid is to be calculated.

Concept introduction: The concentrations of ${\text{H}}_{\text{3}}{\text{O}}^{+}$ and ${\text{OH}}^{-}$ for the given solution is calculated by the formula,

$\left[{\text{H}}_{\text{3}}{\text{O}}^{+}\right]\left[{\text{OH}}^{-}\right]=1.0\times {10}^{-14}$

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