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

Options

A. Exhibit enormous surface area
B. Remain suspended in the dispersion medium
C. Form lyophilic colloids
D. Are comparatively less in number

Answer

D

Explanation

The value of colligative properties of colloidal solution is of small order in comparison to those of true solution of same concentration because of colloidal particles are comparatively less in number.
This is due to slight large size of colloidal particles in comparison to particles present in true solution. Size of colloidal particles is in between 1 nm to 1000 nm.
