WebThe colloidal solutions in which the particles of dispersed phase have no affinity with dispersion medium are called lyophobic sols and the reverse is lyophilic sols. Examples of lyophobic sols are sols obtained from metals like Ag, Au, metal hydroxides like Al(OH) 3 and Fe(OH) 3 and metal sulfides like As 2S 3.. WebIn this kind of colloid, the forces between the colloidal particles are not stable and strong, and it is also known as lyophobic colloids. The word, lyophobic comes from two terms, lyo which means liquid, and phobic which means fear. Hence, they are also considered solvent-hating colloids as they create repulsion force against the water molecules.
