aim- how small are these particles of matter.
materials required- potassium permanganate, beaker and water.
procedure -1 take two -three crystals of potassium and dissolve them in 100ml of water. 2-take out approximately 10ml of this solution and put into 90ml of clear water.
3-take out 10ml of this solution and put into another 90ml of clear water. keep diluting the solution like this 5to 8times.
4-is the water still coloured?
observation -this experiment shows that just a few crystals of potassium permanganate can colour a large volume of water.
coclusion- 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 AMD smaller particles.
hope this help you.
