PERMANGANATE, DICHROMATE AND CERIC SULPHATE TITRATION METHODS
The oxidation and reduction processes essentially take place simultaneously in a reaction, thus one entity gets reduced in the process of oxidizing the second. ‘Redox’—is the abbreviated form of reduction— oxidation systems. In the oxidation—reduction methods of analysis a change in valence of the reacting products is a must which is contrary to precipitation and neutralization methods of analysis where no change in valence occur. The major oxidizing agents normally employed in volumetric titrations include, potassium permanganate, potassium dichromate, and ceric sulphate.
