Chapter 15, Problem 12Q

Interpretation Introduction

Interpretation:

The relation between the $\text{pH}$ of the given buffer solution and the $\text{p}{K}_{\text{a}}$ value of the weak acid is to be determined.

Concept introduction:

The acidic strength of a substance can be determined using its $\text{p}{K}_{\text{a}}$ value. The lower the $\text{p}{K}_{\text{a}}$ value, the stronger is the acid.

To determine: The relation between the $\text{pH}$ of the given buffer solution and the $\text{p}{K}_{\text{a}}$ value of the weak acid.
