Chapter 8, Problem 8.76AP

(a)

Interpretation Introduction

Interpretation:

The $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$ of the solution, whose $\text{pH}$ is $\text{4}$ has to be calculated.

Concept Introduction:

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

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

Concentration of hydronium ion is antilog of $\text{pH}$ of the solution.  It can be calculated using the formula,

  $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]{\text{=10}}^{\text{-x}}$

Where, x=$\text{pH}$ of the solution

(b)

Interpretation Introduction

Interpretation:

The $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$ of the solution, whose $\text{pH}$ is $\text{8}$ has to be calculated.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$ of the solution, whose $\text{pH}$ is $\text{2}\text{.60}$ has to be calculated.

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

The $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$ of the solution, whose $\text{pH}$ is $\text{11}\text{.30}$ has to be calculated.

Concept Introduction:
