Chapter 16, Problem 82E

Interpretation Introduction

Interpretation: The of the solution containing the dissociated ions of pyridinium bromide is given. The molarity of the solution is to be answered.

Concept introduction: The of the weak hydrolyzed salt is determined by the formula:

${\text{pH}}_{\text{salt}}\text{=7-}\frac{\text{1}}{\text{2}}{\text{(pK}}_{\text{b}}{\text{+log C}}_{\text{salt}}\text{)}$

Where C is the concentration of salt.

To determine: The molarity of the solution of pyridinium bromide.
