Redox Titration
INTRODUCTION
This titrimetric method is mainly based upon the change of the oxidation number or electrons transfer between the reactants, that is, these reactions are mainly based upon the oxidation-reduction reactions. In oxidation-reduction titration method, a reducing substance is titrated with standard solution of an oxidizing agent (e.g., ceric ammonium sulphate) or an oxidizing substance is titrated with the standard solution of the reducing agent (e.g., titanous chloride).
PRINCIPLE
The principle involved in the oxidation-reduction titrations is that the oxidation process involves the loss of electrons whereas the reduction process involves the gain of electrons.
Oxidant + ne ↔ Reductant
