. Lyophilic sols are more stable than lyophobic sols because
A: The colloidal particles leave positive charge
B: The colloidal particles have no charge
C: The colloidal particles are solvated
D: There are strong electrostatic repulsions between the negatively charge colloidal particles
- The existence of a charge and the solvation of colloidal particles contribute to the stability of lyophilic sols.
- Lyophobic sols, on the other hand, are only stable because of the presence of a charge.
- Because of the broad solvation, the lyophilic sol is more stable than the lyophobic sol.
Hence, the correct option is (c) The colloidal particles are solvated
