The stabilization of a dispersed phase in a lyophobic colloide sol is due to

A

The adsorption of charged substance on dispersed phase

B

The large electrokinetic potential developed in the colloid

C

The viscosity of the medium

D

the formation of an electrical layer between two phases.

Text Solution

Verified by Experts

The correct Answer is:
D
There is adsorption of common ion on the colloidal sol and an electrical double layer is formed. Thus, dispersed phase in a lyophobic colloidal sol is stabilized.
