Summary Introduction

Interpretation:

The pKa and Ka values of the acetic acid is to be determined.

Concept introduction:

The Henderson–Hasselbalch expression for a weak acid and its conjugate base is as follows:

pH=pKa+log[A][HA]

Here, pH is the measure of the acidity of the solution, pKa is the negative logarithm of the dissociation constant, [HA] is the concentration of weak acid, and [A] is the concentration of its conjugate base.

The pKa value is logarithmic of dissociation constant Ka .

pKalog[Ka]

Here, Ka is the dissociation constant.
