Question

What are lyophilic and lyophobic colloids.....?
... thanks​

Answer 1

Answer:

Lyophobic colloids are liquid hating colloids (Lyo means solvent and phobic means hating). When these colloids are mixed with the suitable liquid, very weak force of attraction exists between colloidal particles and liquid and system does not pass into colloidal state readily.

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.
