Question

Mention any three differences between lyophilic and lyophobic colloids.

Answer 1

Lyophilic colloid	Lyophobic colloid
The affinity between disperse phase and dispersion medium is strong.	The affinity between disperse phase and dispersion medium is weak.
The viscosity of colloid is higher than that of the dispersion medium.	The viscosity of colloid is same as that of the dispersion medium.
The surface tension of colloid is lower than that of the dispersion medium.	The surface tension of colloid is same as that of the dispersion medium.
