Question

Lyophilic sols are more stable than lyophobic sols because : 

(1) there is a strong electrostatic repulsion between the negatively charged colloidal particles. 

(2) the colloidal particles have positive charge. 

(3) the colloidal particles have no charge. 

(4) the colloidal particles are solvated.

Answer 1

Answer is (4) the colloidal particles are solvated.

In the lyophilic colloids, the colloidal particles are extensively solvated.
