Don't stir the water. Observe the changes. Observation :- The colour of the water slowly changes to purple. Conclusion :- The water became purple because the potassium permanganate crystals mix with the water. The crystals mix with water because both water and potassium permanganate particles move continuously.

We can derive the chemical formula of a compound by the following steps given below.   Step 1 :-  Write down the symbols of the elements that make up the compound.   Step 2 :-  Write down the valency of each of the elements below their respective symbols.   Step 3 :-  Interchange the valencies and write them as subscripts next to the symbols.   Step 4 :-  Simplify the formula by dividing the valencies by a common factor, if any. If not divisible by any common number, leave the valencies as they are.
