Chapter 8, Problem 8.73AP

(a)

Interpretation Introduction

Interpretation:

The $\text{pH}$ of the solution, whose hydronium ion concentration is ${\text{1×10}}^{\text{-12}}\text{M}$ has to be calculated and labeled as acidic or basic.

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 solution, whose hydronium ion concentration is $\text{2}{\text{.5×10}}^{\text{-7}}\text{M}$ has to be calculated and labeled as acidic or basic.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The $\text{pH}$ of the solution, whose hydronium ion concentration is $\text{1}{\text{.6×10}}^{\text{-8}}\text{M}$ has to be calculated and labeled as acidic or basic.

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

The $\text{pH}$ of the solution, whose hydronium ion concentration is $\text{1}{\text{.2×10}}^{\text{-2}}\text{M}$ has to be calculated and labeled as acidic or basic.

Concept Introduction:

Refer to part (a).
