Choose the correct reason(s) for the stability of the lyophobic colloidal particles.

A

Preferential adsorption of ions on their surface from the solution

B

Preferential adsorption of solvent on their surface from the solution

C

Attraction between different particles having opposite charges on their surface

D

Potential difference between the fixed layer and the diffused layer of opposite charges around the colloidal particles

Text Solution

Verified by Experts

Lyophobic sol, which is otherwise unstable, gets stabilised by preferential adsorption of ions on the their surface, thus developing a potential difference between the fixed layer and the diffused layer. Thus, option (a) and (d) are correct.
