Chemistry - Surface Chemistry Question with Solution | TestHub

Solution:

Lyophilic sols are more stable due to the strong affinity between the dispersed phase particles and the dispersion medium. This leads to the formation of a solvation layer around the colloidal particles, which protects them from coagulation. This solvation (or hydration if the medium is water) makes them intrinsically more stable than lyophobic sols.

The final answer is C
