Chapter 8, Problem 8.19P

Interpretation Introduction

Interpretation:

The $\text{pH}$ value of $\text{0}\text{.085M}$ pyridinium bromide has to be calculated and the concentrations of pyridine, pyridinium ion and ${\text{Br}}^{\text{-}}$ has to be determined.

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.

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