Chapter 8.5, Problem 8.22P

(a)

Interpretation Introduction

Interpretation:

The $\text{pH}$ of the solution from $\text{1}{\text{.8×10}}^{\text{-6}}\text{M}$ has to be calculated.

Concept Introduction:

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

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

For acidic solution, $\text{pH<7}$

For basic solution, $\text{pH>7}$

For neutral solution, $\text{pH=0}$

(b)

Interpretation Introduction

Interpretation:

The $\text{pH}$ of the solution from $\text{9}{\text{.21×10}}^{\text{-12}}\text{M}$ has to be calculated.

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

The $\text{pH}$ of the solution from $\text{0}\text{.0000000000762M}$ has to be calculated.
