Question

Name the phenomenon which causes one crystal of potassium permanganate to turn a beaker of water purple.

Answer 1

Answer:

When a piece of Potassium permanganate (KMnO₄) is added to or placed at the bottom of a beaker which contains cold water, then the water turns into a purple coloured solution. ... This is due to diffusion of the KMnO₄ particles in the water.

Answer 2

Answer:

diffusion

Explanation:

Diffusion refers to the process by which molecules intermingle as a result of their kinetic energy of random motion. Diffusion is the net movement of molecules or atoms from a region of high concentration (or high chemical potential) to a region of low concentration.
