. 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



Best Answer


  • 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.

Final Answer:

Hence, the correct option is (c) The colloidal particles are solvated
