Detailed Solution

Lyophobic colloids are stable in nature due to the preferential adsorption of ions on their surface from the solution. The repulsion between the particles is carrying the same charge keeps them separated. The particles will not come close together to form large particles that will precipitate out.

The potential difference between the fixed layer and the diffused layer of opposite charge.
