Chapter 15, Problem 15.52SP

(a)

Interpretation Introduction

Interpretation:

$\text{pH}$ of the solution should be given, when the addition of $\text{LiF}$ to an $\text{HF}$ solution.

Concept introduction:

$\text{pH:}$

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

$\text{pH}\text{=}{\text{-log}}_{\text{10}}{\text{[H}}^{\text{+}}\text{]}$

(b)

Interpretation Introduction

Interpretation:

$\text{pH}$ of the solution should be given, when the addition of $\text{KI}$ to an $\text{HI}$ solution.

Concept introduction:

$\text{pH:}$

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

$\text{pH}\text{=}{\text{-log}}_{\text{10}}{\text{[H}}^{\text{+}}\text{]}$

(c)

Interpretation Introduction

Interpretation:

$\text{pH}$ of the solution should be given, when the addition of ${\text{NH}}_{\text{4}}\text{Cl}$ to an ${\text{NH}}_3$ solution.

Concept introduction:

$\text{pH:}$

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

$\text{pH}\text{=}{\text{-log}}_{\text{10}}{\text{[H}}^{\text{+}}\text{]}$
