Question

Choose the correct reason(s) for the stability of the lyophoic 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.

Answer 1

Answer: (A), (D)

Preferential adsorption of ions on their surface from the solution.
Potential difference between the fixed layer and the diffused layer of opposite charges around the colloidal particles.

Lyophobic colloids are stable due to preferential adsorption of ions on their surface from solution and potential difference between the fixed layer and the diffused layer of opposite charges around the colloidal particles that makes lyophobic sol stable.
