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.

Potassium permanganate (KMnO4) solution
so again, my uni made it so clear that there is no such thing called fair.
i have to retake my exam. i picked kmno4 which is highly oxidative which mean the later you do the optical measurement the higher the chance you’ll get the wrong result. so it was 3h30 and it’s my turn, the teacher cut it and let the nitrit use the uv machine:))) so 3 others and i have to wait until all the nitrit finish to do the measurement.
i and the 2 girls cry:))) because by that time kmno4 will all be oxidated and we’ll fail. but what can we do:)))
Bored at work. Might as well burn some glycerin
