Question

Take out approximately 10 mL of this
solution and put it into 90 mL of clear
water.
Take out 10 mL of this solution and
put it into another 90 mL of clear water.
Keep diluting the solution like this 5 to
8 times.
Is the water still coloured ?​

Answer 1

Take 2-3 crystals of potassium permanganate and dissolve them in 100 mL of water. Take out approximately 10 mL of this solution and put it into 90 mL of clear water. Take out 10 mL of this solution and put it into another 90 mL of clear water. Keep diluting the solution like this 5 to 8 times.

Answer 2

I HOPE THIS HELPS YOU

Explanation:

This experiment shows that just a few crystals of potassium permanganate can colour a large volume of water( about 1000L). So we conclude that there must be millions of tiny particles in one crystal potassium permanganate, which keep on diving themselves into smaller and smaller particles
