Chapter 17, Problem 133AP

Interpretation Introduction

Interpretation:

The solution containing the highest concentration of ${\text{H}}_3{\text{O}}^{+}$ ions is to be identified, out of the given options.

Concept introduction:

The solutions containing weak acids and their conjugate basesor weak bases and their conjugate acids are known as buffer solutions.

These solutions can resist change in $\text{pH}$ of a solution on addition of a base or an acid.
