Report Error
A
Preferential adsorption of ions on their surface from the solution
16%
B
Preferential adsorption of solvent on their surface from the solution
22%
C
Attraction between different particles having opposite charges on their surface
22%
D
Potential difference between the fixed layer and the diffused layer of opposite charges around the colloidal particles
41%
Solution:
Lyophobic sol, which is otherwise unstable, gets stabilised by preferential adsorption of ions on their surface, thus developing a potential difference between the fixed layer and the diffused layer. Thus, option (a) and (d) are correct.
