The disappearance of pink colour may take place with or without the formation of brown precipitate of manganese oxide. The test involves adding a standard solution of potassium permanganate to the product. MnO 4-8H 5e-® Mn 2 4H 2 0. Oxidisable impurities discharge the pink permanganate colour over a period of time. The standard tests often call for the mixture to be left for periods up to 2 hours before checking the colour.

oxalate, and nitrite. Controlled reactions combining these reductants with permanganate need to be performed to determine the rate at which each reacts, to what the permanganate is reduced to, and what products are created. Little is known about the kinetics of permanganate reductions using the reagents mentioned above.

In this test the permanganate feed increased by 60% and its residual increased by approximately 50%, so the difference was about 10%.
