Chapter 1, Problem 12P

Interpretation Introduction

Interpretation:

The total concentration of acetic acid added is to be determined.

Concept introduction:

The value of the concentration of acetic acid can be determined using the following expression,

${\text{K}}_{\text{a}}=\frac{\left[{\text{CH}}_{\text{3}}{\text{COO}}^{-}\right]\left[{\text{H}}^{+}\right]}{\left[{\text{CH}}_3\text{COOH}\right]}$

Where,

• $\left[{\text{CH}}_3{\text{COO}}^{-}\right]$ is the concentration of acetate ion.
• $\left[{\text{CH}}_3\text{COOH}\right]$ is the concentration of acetic acid.
• $\left[{\text{H}}^{+}\right]$ is the concentration of hydrogen ions.
• $K_{\text{a}}$ is equilibrium constant of the acid.
