1.Dissolve a few crystals of potassium permanganate in 100 ml of water.

2.Take out approximately 10 mL of this solution and add it to 90 mL of clear water taken in another beaker.

3.Now from this solution, take 10 ml of the solution and add it 90 ml of water taken in another beaker.

4. In the same manner Keep diluting the solution like this 5 to 8 times.


This experiment shows that just a few crystals of potassium permanganate can colour a large volume of water (about 1000 L).


This activity proves that matter is made up of tiny particles. So we conclude that there must be millions of tiny particles in just one crystal of potassium permanganate, which keep on dividing themselves into smaller and smaller particles. Ultimately a stage is reached when the particles cannot divide further into smaller particles.
