Question

estimate how small are the particles of matter. with every dilution though how is the colour becomes ?​

Answer 1

Answer:

Estimating how small are the particles of matter. With every dilution, though the colour becomes light, it is still visible. ... 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

Answer 2

Answer:

The colour becomes light , it is still visible.

Explanation:

. For  a long time two schools of thought prevailed regarding the nature of matter . one school believed matter to be continuous like a block of wood , whereas , the other thought that the matter was made up of particles like sand .

. Let us perform an activity to decide about the nature of matter - is continuous or particulate ?

. 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 ?

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

( Note : you can also use Dettol instead of potassium )
