Question

25. Why copper sulphate solution in water does not show tyndall effect, but mixture of water
and milk shows,​

Answer 1

Answer:

Copper sulphate solution in water does not show tyndall effect the particles of solution are very small to be abke to make the light path visibke whereas a milk is a colloid whise particle size is big enough to scatter a beam of light and make the path visible.

Answer 2

1. The scattering of light by colloidal particles is known as Tyndall effect.
2. Milk is a colloidal solution which appears to be homogeneous but actually it is heterogeneous. The particles of milk are big enough to scatter light. Hence milk shows Tyndall effect.
3. The copper sulphate solution in water is a true solution which is homogeneous. The particles are very small and do not scatter light. Hence copper sulphate solution in water does not show Tyndall effect.
