What happens to the potassium permanganate crystals when added to the beaker of hot water placed above the burner ?

a) When potassium permanganate crystals are placed in hot water, the solution turns to purple in color because of a process called diffusion. Diffusion is the movement of molecules or atoms from high concentrated region to low concentrated region.

b) So, when you place potassium permanganate crystals in hot water, the tiny molecules of the crystals spread through the entire solution and change the color to purple. 

c) Diffusion is such a strong process that there is no need even to stir the water. When the crystals are placed, they automatically diffuse and spread through the entire solution.
