Question

When a crystal of potassium permanganate is placed in a beaker containing water its purple colour spreads through out the water.what do you conclude from this observation about the nature of potassium permanganate and water

Answer 1

Answer :

When we place a few crystals of potassium permanganate in a beaker containing water, we get two layers:

Colourless water at the top and pink colour at the bottom.

After a few minutes, a light pink colour spreads and the entire solution turns pink due to diffusion.

As potassium permanganate is a solid substance, it does not possess so much space.

Water molecules due to a liquid state, collide with solid particles and intermix due to sufficient space between molecules.

Answer 2

Answer:

This shows the diffusion of particles of water and potassium permanganate,due to this property only the dissolution and spreading of the color of potassium.
