Chapter 8.4, Problem 8.11Q

Interpretation Introduction

Interpretation:

The $\text{pH}$ of buffer acetic acid and sodium acetate solution has to be calculated.

Concept Introduction:

Buffer solution:  It consists of components that resist the change in $\text{pH}$ of the solution when either acids or bases are added.  The buffer solution is a combination of weak acid or base and its conjugate acid or base.

The Henderson-Hasselbalch equation is given by

    $\text{pH}\text{=}{\text{pK}}_{\text{a}}\text{+}\text{log}\frac{\text{[Conjugate}\text{base]}}{\text{[acid]}}$
