In lyophilic sols, the dispersed phase particles have great affinity (or love) for the dispersion medium. These sols are reversible. Examples include gum, gelatin, starch, proteins and rubber etc.

In lyophobic sols, the dispersed phase particles have no affinity (or love) for the dispersion medium. These sols are irreversible. Examples include solutions of metals such as gold and silver, metal hydroxides and metal sulphides.

The hydrophobic sols are less stable and easily coagulated than hydrophilic sols because, the stability of  hydrophobic sols is due to charge only and the stability of hydrophilic sols is due to charge and solvation/ hydration.

Answer 2

Answer:

Lyophilic colloids are liquid loving colloids (Lyo means solvent and philic means loving). When these colloids are mixed with the suitable liquid, high force of attraction exists between colloidal particles and liquid.

2. The potential difference existing between the surface of a solid particle immersed in a conducting liquid (e.g. water) and the bulk of the liquid.

3. Association colloids are micro heterogeneous systems in which the particles of the colloidal dispersed phase (micelles) are formed by the agglomeration of molecules or ions of the substance dissolved in the dispersion medium.
