Question

Choose the correct reasons for stability of Lyophobic colloidal particles a) Preferential adsorption of ions on their surface from solution b) Preferential adsorption of solvent on their surface from 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 1) a & c 2) a & d 3) b, c & d 4) a, b, c & d

Answer 1

Explanation:

1. Lyophobic colloids adsorb , Electrolytes not Solvents from the solution
2. to form a layer of opposite charge potential called zeta potential.Also hier will be no affinity b/w the particles that are attached with their layers.

Preferential adsorption of solvent on their surface from solution is wrong

Attraction between different particles having opposite charges on their surface is wrong
