Answered by Anonymous

Answer:

A beaker is almost filled with water. Some crystals of CuSO4 or KMnO4 are dropped carefully without disturbing water and is left as such for some time.

Observation:

The water is uniformly coloured, blue in case of CuSO4 and pink in case of KMnO4.

Inference:

ADVERTISEMENTS:

The molecules of the chemicals diffuse gradually from higher concentration to lower concentration and are uniformly distributed after some time. Here, CuSO4 or KMnO4 diffuses independently of water and at the same time water diffuses independently of the chemicals.
