Answer 2

$\huge\rm\underline\purple{Answer:-}$

Lyophilic sols are reversible in nature. ... Lyophobic sols are those in which the dispersed phase has no attraction for the dispersion medium or the solvent. Their colloidal sols can be prepared only by special methods and they are irreversible in nature.

More information :

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
