Filtration of manganese dioxide from an oxidation that used potassium permanganate as an oxidant.
The characteristic purple color of the remaining small amount of permanganate is seen in the filtrate. Even through only a small amount remained from the original amount it still has a quite intense color. Important to note that contact with skin will result in a long lasting pinkish/purple stain.
Did you know that potassium permanganate is used extensively in the water treatment industry? It is used to disinfect drinking water and it can turn the water pink in some cases.
