THREE PHASE EFFECT ON REDOX SYSTEMS USING AMPEROMETRY

Phase effect on amperometric titration of cerium (IV) sulphate tetrahydrate with iron (II) ammoniumsulphate hexahydrate and potassium permanganate with iron (II) ammonium sulphate hexahydrate redoxsystems were studied at a platinum test electrode and Ag | AgCl reference electrode at 1.8 V and 1.2 V.Two-phase effect on amperometric titration of these redox systems has already been studied. This paperpresents the effect of three-phase on the equivalence point and diffusion current (both I d initial and Id final)of the above said redox systems.
