Lyophilic colloids | Lyophobic colloids |
(1) Substances which can on shaking with dispersion medium eg. water form colloids rapidly are called lyophilic colloids. (2) Viscosity is higher than that of dispersion medium (Solvent). | (1) Substances which do not form colloided system with dispersion medium easily are called lyophobic colloids. (2) Viscosity is equal to that of dispersion medium. |
