Chapter 20, Problem 20.21P

Interpretation Introduction

Interpretation:

The $\text{pH}$ value and the concentrations of other species in $\text{0}\text{.0200 M}$${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}\text{COOH}\left(aq\right)$ have to be calculated.

Concept introduction:

$\text{pH}$: The concentration of hydrogen ion is measured using $\text{pH}$ scale. The $\text{pH}$ of a solution is a figure that expresses the acidity or the alkalinity of a given solution.

It is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration.

  $\text{pH}\text{=}{\text{-log[H}}_{\text{3}}{\text{O}}^{\text{+}}\text{]}$
