Chapter 16.8, Problem 11PE

Interpretation Introduction

Interpretation: The ratio of sodium ascorbate to ascorbic acid required to make a buffer with $\text{pH}=\text{5}\text{.25}$ is to be calculated.

Concept introduction: The solution that is able to maintain its $\text{pH}$ when acid or alkali added to it is known as a buffer solution. The solution is usually made up of a weak base and its conjugate acid or a weak acid and its conjugate base, which exist in equilibrium.

To determine: The ratio of sodium ascorbate to ascorbic acid required to make a buffer with $\text{pH}=\text{5}\text{.25}$.
