Chapter 19.4, Problem 2P

Interpretation Introduction

Interpretation:

The $\left[\text{lactate}/\text{lactic}\text{acid}\right]$ ratio is to be detremined for each part at different pH.

Concept Introduction:

At particular $\text{pH}$, the Henderson-Hasselbalch equation can be used to identify the ratio of concentrations of an acid and its conjugate base. The ratio of the concentration of an acid and its conjugate base is calculated by the formula,

$\frac{\left[\text{conjugate}\text{base}\right]}{\left[\text{acid}\right]}={10}^{\left(\text{pH}-\text{p}{K}_{\text{a}}\right)}$
