Potassium permanganate is a widely used oxidizing titrant. It acts as a self-indicatorfor end-point detection and is a very strong oxidizing agent . The solution is stable if precautions are taken in its preparation. When the solution is first prepared, small amounts of reducing impurities in the solution reduce a small amount ofthe MnO4-. In neutral solution, the reduction product of this permanganate is MnO2,rather than Mn2+ produced in acid medium. The MnO2 acts as a catalyst for further decomposition of the permanganate, which produces more MnOz, and so on. This iscalled autocatalytic decomposition. The solution can stabilized by removing theMnO2. So, before standardizing, the solution is boiled to hasten oxidation of all impurities and is allowed to stand overnight. The MnO2 is then removed by filtering through asintered-glass filter. Potassium permanganate can be standardized by titrating primarystandard sodium oxalate, Na2C2O4, which, dissolved in acid, forms oxalic acid.
The solution must be heated for rapid reaction. The reaction is catalyzed by theMn2+ product and it goes very slowly at first until some Mn2+ is formed. Pure electrolytic iron metal can also be used as the primary standard. It is dissolved in acid and reduced to Fe2+ for titration (see below, under Preparation of the Analyte Solution) .
