Chapter 8, Problem 8.24P

(a)

Interpretation Introduction

Interpretation:

The $\text{pH}$ value and fraction of dissociation of ${\text{10}}^{\text{-2}\text{.00}}\text{ M}$ barbituric acid has 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.

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