Chapter 14, Problem 121IP

Interpretation Introduction

Interpretation:

The titration of ${\text{NH}}_{\text{3}}$ with $\text{HCl}$ is given. The $\text{pH}$ at which equivalence point occurs is to be calculated.

Concept introduction:

The solution of weak acid and their conjugate base which upon addition of an acid or base resists the change in $\text{pH}$ is called buffer solution. The $\text{pH}$ of the buffer solution remains constant.

To determine: The $\text{pH}$ of given solution formed by mixing $\text{HF}$ with $\text{NaOH}$.
