Chapter 16, Problem 26RQ

Interpretation Introduction

Interpretation:

Reason for no change in $\text{pH}$ of buffer solution on addition of acid or base has to be explained.

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
