Question

BE THE FIRST TO BE BRAINLIEST explain the activity of potassium permanganate? ? How does it show How small are these particles of matter???

Answer 1

(i) Take 2-3 crystals of potassium permanganate and dissolve them in 100 ml of water.

(ii) Take out approximately 10 ml of this solution and put it into 90 ml of clear water.

(iii) Take out 10 ml of this solution and put it into another 90 ml of clear water.

(iv) Keep on diluting the solution like this 5 to 8 times.

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

Answer 2

Take a beaker in which add 50 ml of water. Add 2 - 3 crystals of potassium permanganate in it and mix it with a glass rod. You will observe that the colour of the solution is pink.
Take 4 beakers and add 40 ml of water in them. Add 10ml of solution of 1st beaker to the second and mix. Continue this process untill all the beakers have became a solution. You will observe that the first beaker has dark pink colour and the colour goes light after every beaker. This shows that particles are very very small.
