Chapter 9, Problem 9.20P

(a)

Interpretation Introduction

Interpretation:

Volume of $\text{HCl}$ required to prepare sodium acetate buffer of 5 $\text{pH}$ hasto be calculated.

Concept Introduction:

$\text{pH}$ is calculated by Henderson-HasselBalch equation given as follows:

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

Here,

$\text{p}{K}_{\text{a}}$ denotes characteristic acid dissociation constant of diprotic acid.

(b)

Interpretation Introduction

Interpretation:

Preparation for sodium acetate buffer of 5 $\text{pH}$ has to be described.

Concept Introduction:

Refer to part (a).
