Question

Explain the diffusion in liquids with two examples.

Answer 1

1. Diffusion is the process of mixing one substance with another through the motion of its particles.
2. Liquid particles possess sufficient mobility due to kinetic energy to allow for diffusion.
3. This is the process by which two liquids combine when kept together.

Example 1: The purple colour of potassium permanganates spreads into the water on its own.
Example 2: The spontaneous spread of blue copper sulphate into the water.
