Question

Explain how a lyophillic colloid can stabilize a lyophobic colloid

Answer 1

A lyophilic sol is stable due to the charge and the hydration of sol particles. ... On the other hand, a lyophobic sol is stable due to the charge only and hence can be easily coagulated by adding small amount of an electrolyte

Answer 2

Answer:

(1) Lyophilic colloids : The sols in which there is a strong affinity between the dispersed phase and the dispersion medium are called lyophilic colloids.

(2) Lyophobic colloids : The sols in which there is little affinity between the dispersed phase and the dispersion medium are called lyophobic colloids.
