Question

colloidal solution show tyndall effect but true solution do not.Explain.  

Answer 1

The  particles present in colloidal solution are between the sizes 10 and 100 angstrom. They can scatter light to a considerable extent. But the particles present in true solution are very small that they cannot scatter light at all. Hence colloidal solution show tyndall effect but true solution does not.

Answer 2

Answer:

Explanation:

(a) Colloidal solutions show Tyndall effect but true solutions do not. ... But in a true solution, the particle size is so small (less than 1nm) that these particles are not in a position to scatter the light. Therefore, true solution does not show any Tyndall effect.
