Chapter 16, Problem 16.103QP

Interpretation Introduction

Interpretation: The effect on $\text{pH}$ and buffer capacity on addition of $100\text{mL}$ of water to the $100\text{mL}$ buffer solution of acetic acid and sodium acetate is to be predicted.

Concept introduction: A buffer solution is defined as a solution of a weak acid and its conjugate base or a weak base and its conjugate acid that resists the change in $\text{pH}$ on the addition of small quantity of acid or base.

To determine: The effect on $\text{pH}$ and buffer capacity on addition of $100\text{mL}$ of water to the $100\text{mL}$ buffer solution of acetic acid and sodium acetate.
