Lyophobic colloids are stabilized primarily by electrical repulsion due to ion adsorption. Solvent adsorption is minimal as they are solvent-hating. Attraction between opposite charges would cause coagulation, not stability. The key reason is the formation of an electrical double layer.
The potential difference between the fixed inner layer and the mobile diffused layer of ions, known as the zeta potential (-potential), creates repulsive forces that prevent particle aggregation.
Final Answer: 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.
