Chapter 1, Problem 24P

Interpretation Introduction

Interpretation:

The quantity (moles and grams) of acetic acid and sodium hydroxide required to prepare a buffer is to be determined.

Concept introduction:

Henderson and Haselbalch equation is used to find the concentrations. The expression is as given below,

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

Where,

• $\text{p}{K}_{\text{a}}$ is dissociation constant.
• $\left[\text{Salt}\right]$ is the concentration of salt.
• $\left[\text{Acid}\right]$ is the concentration of acid.
