Chapter 16, Problem 25RQ

Interpretation Introduction

Interpretation:

Acetic acid-sodium acetate $\left({\text{CH}}_3\text{COOH}+{\text{CH}}_3\text{COONa}\right)$ buffer system maintains its $\text{pH}$ when $0.010\text{mol}$ of $\text{HCl}$ is added to $1\text{L}$ of buffer solution has to be determined.

Concept Introduction:

Solution that causes resistance in change of $\text{pH}$ due to dilution or addition of acid is termed as buffer solution. Two types of buffer solutions are as follows:

1 Weak acid mixed with salt of its conjugate base.

2 Weak acid mixed with salt of its conjugate acid.
