Give one main difference between lyophobic and lyphilic colloids.

Text Solution

Verified by Experts

In lyophilic colloids, there is an attraction between particles of dispersed and dispersion medium while repulsive forces dominate among the particles in a lyophoboc sol. Therefore, lyophilic sol is readily formed while formation of lyophoboc sol is rather difficult.

Lyophobic colloids

Collidal solution is a heterogeneous solution which contains particle of intermediate size, i.e., (diameter between 1 and 1000 nm) colloidal is not a substance but it is a state of a substance which depends upon the molecular size.
