Chapter 25, Problem 44P

Interpretation Introduction

Interpretation:

The equations should be written which illustrates the reaction between buffer and excess acid and excess base.

Concept Introduction:

The phosphate or the hydrogen phosphate-dihydrogen phosphate is responsible for the maintenance of the pH of the blood. The buffer maintains an equilibrium between the dihydrogen phosphate and hydrogen phosphate which results in the acceptance or donation of the

${\text{H}}^{+}$ ion when there is a need.
