Chapter 6, Problem 6.6YT

Interpretation Introduction

Interpretation:

In figure 6.1, pH units above the acid’s pKa to cause the acid to dissociate nearly $\text{100\%}$ and pH units below the acid’s pKa to cause the acid to be nearly $\text{100\%}$ associated are to be determined.

Concept introduction:

An acid dissolved in water dissociates $\text{50\%}$ when the solution’s pH is equal to the acid’s pKa.

In the equilibrium between an acid (HA) and water, increasing the solution’s pH causes an increase in the percent dissociation of the acid into its conjugate base.
