A coulometric titration curve needs to be constructed containing 100.0 mL of a 1 M H2SO4 solution in which Fe(II) is titrated against Ce(IV) which is generated from 0.075 M Ce(III).
In coulometric titrations, a constant current is used to generate the titrant electro-analytically. In some coulometric titrations the analyte may be directly involved at the generator electrode. For example, the coulometric titration of Fe(II) in part by electro-analytically generated Ce(IV) and in part by direct electrode reaction.
