Chapter 16, Problem 38QP

Interpretation Introduction

Interpretation:

The pH values of aqueous solutions are to be determined, when the concentrations of acids are given.

Concept introduction:

A strong acid is an electrolyte that completely dissociates, when dissolved in water, to produce hydronium ions and its conjugate base.

$\text{BOH}\left(aq\right)\to {\text{B}}^{\text{+}}\left(aq\right)+{\text{OH}}^{-}\left(aq\right)$

pH is the measure of acidity of a solution and it depends on the concentration of hydronium ions and the temperature of the solution.

The formula to calculate the pH is:

$\text{pH}=-\log \left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$ …… (1)
