Question

even two or three crystals of potassium permanganate can impart colour to a very large volume of water. which characteristic of particles of matter is illustrated by this observation?

Answer 1

As we know that particles of matter are in constant motion, the particles of potassium permanganate are in constant motion, too. When put in a unit volume of water the particles of potassium permanganate move to fill the intermolecular space between the molecules of water. This is the reason why the colour of water changes when potassium permangate is put into it. This mixing of molecules is called Diffusion.

Answer 2

Explanation:

in the observation it displays that each crystal of potassium permanganate must be made up of millions of small particles.
