JEE Main Chemistry question

Not in JEE Main or NEET syllabus

Lyophilic sols are more stable than lyophobic sols because:

(A)The colloidal particles have a positive charge
(B)The colloidal particles have no charge
(C)The colloidal particles are solvatedCorrect
(D)There are strong electrostatic repulsions between the negatively charged colloidal particles

Answer: (C)

Solution

In lyophilic sols, the dispersed particles have a strong affinity for the dispersion medium and become surrounded by a sheath of adsorbed solvent molecules (solvation), which provides an additional layer of
