Chapter 14, Problem 14.65SP

(a)

Interpretation Introduction

Interpretation:

$\text{pH}$ of the solution which has concentration of ${\text{OH}}^{\text{-}}$ ion as $7.6\times {\text{10}}^{-3}\text{ M}$ has to be calculated.

Concept introduction:

$\text{pH}$ is an logarithmic expression to express a solution is acidic, basic or neutral.  $\text{pH}$ scale values lies between 1-14 and on which 7 is neutral, below 7 values are more acidic in nature and above 7 values are more basic in nature.

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

(b)

Interpretation Introduction

Interpretation:

$\text{pH}$ of the solution that has concentration of ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}$ is ${10}^{-8}$ M has to be calculated.

Concept introduction:

$\text{pH}$ is an logarithmic expression to express a solution is acidic, basic or neutral.  $\text{pH}$ scale values lies between 1-14 and on which 7 is neutral, below 7 values are more acidic in nature and above 7 values are more basic in nature.

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

$\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]{\text{= antilog(-pH) =10}}^{\text{-pH}}$

(c)

Interpretation Introduction

Interpretation:

$\text{pH}$ of the solution that has concentration of ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}$ is $5.0$ M has to be calculated.

Concept introduction:

$\text{pH}$ is an logarithmic expression to express a solution is acidic, basic or neutral.  $\text{pH}$ scale values lies between 1-14 and on which 7 is neutral, below 7 values are more acidic in nature and above 7 values are more basic in nature.

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

$\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]{\text{= antilog(-pH) =10}}^{\text{-pH}}$

(d)

Interpretation Introduction

Interpretation:

$\text{pH}$ of the solution has concentration of ${\text{OH}}^{\text{-}}$ is $\text{1}\text{.0}\times {\text{10}}^{-7}\text{ M}$ has to be calculated.

Concept introduction:

$\text{pH}$ is an logarithmic expression to express a solution is acidic, basic or neutral.  $\text{pH}$ scale values lies between 1-14 and on which 7 is neutral, below 7 values are more acidic in nature and above 7 values are more basic in nature.

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

(e)

Interpretation Introduction

Interpretation:

$\text{pH}$ of the solution that has concentration of ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}$ is $\text{2}{\text{.18×10}}^{\text{-10}}\text{M}$ M has to be calculated.

Concept introduction:

$\text{pH}$ is an logarithmic expression to express a solution is acidic, basic or neutral.  $\text{pH}$ scale values lies between 1-14 and on which 7 is neutral, below 7 values are more acidic in nature and above 7 values are more basic in nature.

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

$\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]{\text{= antilog(-pH) =10}}^{\text{-pH}}$
