1. Take a beaker full of water.
2. Add a few crystals of potassium permanganate to it.
3. We observe that the diffusion of potassium permanganate crystal into water and the colour of water changes.
4. Repeat the experiment with crystals of copper sulphate.
5. Here also we observe the diffusion of CuSO4 crystals into water and the colour of water changes.
6. From the above observations, we found that the particles of solids diffuse into liquids.
