Solvent hating colloidal system
WebLyophobic colloid (solvent hating): The dispersed phase has little attraction to the solvent (solvent hating). Their properties differ from the lyophilic (hydrophilic). They are usually inorganic n nature e.g. gold, silver, sulphur. In contrast to lyophilic colloid, it is necessary to use special method to prepare hydrophobic colloid. Web6 Solid sol Colloidal system where dispersed phase is solid and the dispersion medium is another continuous solid. ... (solvent loving) colloids, while suspenoids are lyophobic (solvent hating) colloids. Suspenoids are less viscid and less stable than emulsoids. Examples for emulsions include protein, starch and egg white solution.
