Coulometric titration

The technique and its application
The technique of coulometric titration was originally developed by Szebelledy and Somogy [1] in 1938. The method differs from volumetric titration in that the titrant is generated in situ by electrolysis and then reacts stoichiometrically with the substance being determined. The amount of substance reacted is calculated from the total electrical charge passed, Q, in coulombs, and not, as in volumetric titration, from the volume of the titrant consumed.
