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 ...
Add 10 to 15 drops of glycerol to the depression in the center of a pile of finely ground potassium permanganate in an evaporating dish on a heat proof surface. Stand back! Within a few seconds, the ...
After one hour, equilibrium has been reached which means the potassium permanganate crystals are at an equal concentration throughout the water. Diffusion has stopped.
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 ...
