Potentiometric Titration

Potentiometric titration is a traditional and definitive method for pKa determination. A diagram of this approach is shown in Figure 24.6. The compound is dissolved in water and titrated with an acidic or basic buffer of known molarity. In the classical potentiometric method, the pH of the test solution changes as the titrant is added.
