Chapter 8, Problem 8.79AP

(a)

Interpretation Introduction

Interpretation:

The $\text{pH}$ of the aqueous solution of $\text{0}\text{.0025M}\text{HCl}$ has to be calculated.

Concept Introduction:

$pH:$  The measure of concentration of hydrogen ions is called as $\text{pH}$ of the solution.  The acidic and basic nature of solution can be determined from its $\text{pH}\text{.}$

The $\text{pH}$ of the solution is calculated using the formula,

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

(b)

Interpretation Introduction

Interpretation:

The $\text{pH}$ of the aqueous solution of $\text{0}\text{.015M}\text{NaOH}$ has to be calculated.

Concept Introduction:

Refer to part (a).
