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

Options

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

Answer

A, D

Explanation

In case of lyophobic sols, the ionic colloid adsorbs ions common to its own lattice during the preparation of the sol. So they are stable and also the potential difference which arises between the fixed layer and the diffused layer makes lyophobic sols.more stable.
