Chapter 16, Problem 16.102QP

Interpretation Introduction

Interpretation: The validation of the fact that a buffer solution prepared from ammonia $\left(\text{p}{K}_{\text{b}}=4.75\right)$ and ammonium chloride has the same $\text{pH}$ as the one prepared from phenol $\left(\text{p}{K}_{\text{a}}=9.89\right)$ and sodium phenolate is to be stated.

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 validation of the fact that a buffer solution prepared from ammonia $\left(\text{p}{K}_{\text{b}}=4.75\right)$ and ammonium chloride has the same $\text{pH}$ as does the one prepared from phenol $\left(\text{p}{K}_{\text{a}}=9.89\right)$ and sodium phenolate.
