Choose the correct reason(s) for the stability of the lyophobic colloidal particles. — Surface Chemistry Chemistry Question

💡 Solution & Explanation

Lyophobic sols lack affinity for the solvent and are mainly stabilized by electrostatic repulsion. This charge originates from the preferential adsorption of specific ions on the particle surface from the dispersion medium. The resulting potential difference (zeta potential) between the fixed ionic layer and the diffused double layer generates repulsion between particles, preventing coagulation. Therefore, correct answer is A,D.
