Set up a heat resistant mat next to an operating vent in the bench top. Add 10 to 15 drops of glycerol to the depression in the center of a pile of finely ground potassium permanganate in an ...

This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate. The reaction produces a lot of heat so the substance shooting out of the bottle is water vapor that is ...

Convection in a liquid Convection in a liquid can be seen by putting a crystal of potassium permanganate in a beaker of water and gently heating it with a Bunsen flame. Air current close to a ...

POTASSIUM permanganate (1 per cent solution, containing 2 per cent sodium carbonate) has been recommended 1 as a spraying reagent for detecting carbohydrates on paper chromatograms. When testing ...
