Solution
Lyophilic sols are reversible in nature, whereas lyophobic sols are irreversible in nature.
Explanation:
Lyophilic sols (liquid-loving) have a strong affinity for the dispersion medium, are stable, are heavily hydrated, and can be easily prepared. They are reversible, meaning if the dispersed phase separates, it can be redispersed by simply mixing again. In contrast, lyophobic sols (liquid-hating) have little affinity for the dispersion medium, are less stable, require special methods for preparation, and once precipitated cannot be easily redispersed; hence, they are irreversible. Lyophilic sols do not require stabilizing agents, but lyophobic sols do.
