Potassium permanganate

Material required :-

1) Some Potassium permanganate ) 

2) Some water

Procedure :- 

1) Take a glass tumbler which is filled with water 

2) Now, slowly add some Potassium Permanganate crystals in that glass tumbler which is filled with water. 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.
