Question

Why potentiometric titration is required over normal acid base indicator

Answer 1

The titrant flows past a reference electrode before an indicator electrode. Reagent water is added if necessary to cover electrodes. Potentiometric titration requires measurement by electrodes of voltage change across the sample or analyte. ... Potential is measured in millivolts

Answer 2

Volumetric method in which the potential between 2 electrodes is measured as a function of added reagent volume

This technique is similar to direct titration of redox reaction , it is useful 2 characterizing an acid, no indicator is used
