Chapter 2, Problem 48RE

Interpretation Introduction

Interpretation:

The ratio of conjugate base/conjugate acid is to be determined.

Concept information:

Buffers are the solutions that have the capability of resisting any kind of change.

On the other hand, a buffer system is the solution that is capable of resisting any change in the pH, if small quantity of a strong base or a strong acid is added to it.

The Henderson–Hasselbalch equation is the equation that states the relationship between the ${\text{pK}}_{\text{a}}$ value of an acid and the pH of a solution that contains an acid along with its conjugate base. The equation is as follows:

$\text{pH}={\text{pK}}_{\text{a}}+\text{log}\left[\frac{{\text{A}}^{\text{-}}}{\text{HA}}\right]$
