Determination of Concentration of KMnO4 Solution Using Oxalic Acid

The oxidation and reduction reactions in aqueous solutions involve the transfer of electrons from one species to another. In the oxidation of a substance electron(s) is (are) transferred from the species and in reduction, electron(s) is (are) gained by the species. Oxidation and reduction reactions occur simultaneously. A reaction, which involves simultaneous oxidation and reduction, is called a redox reaction. The titrations involving redox reaction are called redox titrations. In Redox titrations involving potassium permanganate, it acts as a powerful oxidising agent.

This video explains how to determine the strength of potassium permanganate solution by titrating it against a standard solution of Oxalic acid.
