Q37.Lyophilic sols are more stable than lyophobic sols because: (1) the colloidal particles have no charge. (2) the colloidal particles have positive charge. (3) the colloidal particles are solvated. (4) there is a strong electrostatic repulsion between the negatively charged colloidal particles.
What This Question Tests
This question tests the understanding of the fundamental reason for the higher stability of lyophilic colloids, which is attributed to the extensive solvation of their colloidal particles by the dispersion medium.
