Chapter 16, Problem 16.16QP

Interpretation Introduction

Interpretation: The change in the $\text{pH}$ of the given buffer solution on addition of the salt of conjugate base is to be stated.

Concept introduction: The $\text{pH}$ of the solution is calculated by the formula,

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

To determine: The change in the $\text{pH}$ of buffer solution of $\text{HF}$ with $\text{NaF}$ on addition of $\text{NaF}$.
