Chapter 16, Problem 16.91QP

Interpretation Introduction

Interpretation: The given question stated that two buffers are prepared with equal concentration of acid and conjugate base using weak acids with different acidic strength $\left(\text{p}{K}_{\text{a}}\right)$ values. They have the same buffer capacity is to be stated.

Concept introduction: Buffer is an aqueous solution that contains mixture of weak base and its conjugate acid or reverse of it. Buffer has highly stable $\text{pH}$. It resists the change in $\text{pH}$ when small amount of acid or base is added to it.

To determine: The buffer capacity of two buffers having equal concentration of acid and conjugate base.
