Chapter 10, Problem 10.14P

(a)

Interpretation Introduction

Interpretation:

Molarity of weak acid has to be calculated.

Concept Introduction:

Dilution formula is given as follows:

  $M_1{V}_1=M_2{V}_2$

Here,

$M_1$ denotes molarity of acid solution.

$V_1$ denotes volume of acid.

$M_2$ denotes molarity of base.

$V_2$ denotes volume  of base.

(b)

Interpretation Introduction

Interpretation:

Formal concentration at equivalence point has to be calculated.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Value of $\text{p}{K}_{\text{a}}$ has to be calculated.

Concept Introduction:

Formula to compute $\text{pH}$ for a salt formed from a weak acid and strong base is as follows:

  $\text{pH}=\frac{1}{2}\left(\text{p}{K}_{\text{w}}+\text{p}{K}_{\text{a}}+\log \left[\text{Salt}\right]\right)$

Here,

$\text{p}{K}_{\text{w}}$ is characteristic of ionic product of water.

$\text{p}{K}_{\text{a}}$ is characteristic of a weak acid.

$\left[\text{Salt}\right]$ denotes the concentration of salt formed from weak acid and strong base.

(d)

Interpretation Introduction

Interpretation:

Value of $\text{pH}$ has to be calculated.

Concept Introduction:

Refer to part (c).
