The values of colligative properties of colloidal solutions are of small order in comparision to those shown by true solutions of same concentration because of colloidal particles

A

exhibit enormous surface area.

B

remain suspended in the dispersion medium.

C

form lyophilic colloids.

D

are comparatively less in number.

Text Solution

Verified by Experts

The correct Answer is:
