Chapter 7, Problem 68P

Interpretation Introduction

Interpretation: The concentration of hydrogen ion needs to be determined.

Concept Introduction: For the given reaction as follows:

${\mathrm{CH}}_{3}COOH\left(aq\right)\rightleftharpoons {\mathrm{CH}}_{3}CO{O}^{-}\left(aq\right)+{\text{H}}^{+}\left(aq\right)$

The expression for equilibrium reaction is represented as follows:

$K_a=\frac{\left[{\mathrm{CH}}_{3}CO{O}^{-}\right]\left[{\text{H}}^{+}\right]}{\left[{\mathrm{CH}}_{3}C\text{OOH}\right]}$
