Chapter 17, Problem 109AP

Interpretation Introduction

Interpretation:

The reason for the statement “ little practical use of ${\text{Al}}_{\text{2}}{\text{O}}_{\text{3}}$ and $\text{BeO}$ as buffer components in the preparation of buffer solutions” is to be explained.

Concept introduction:

The oxides that can react as an acid as well as a base in a reaction are known as amphoteric oxides. These oxides are insoluble in water.

The aqueous solution that consists of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid is known as a buffer solution. Little change occurs in the pH of a buffer solution if a small amount of base or acid is added to it.
