1) lyophobic sols :
They are those solution in which the dispersed phase has no attraction for the dispersion medium or the solvent. For eg. Dispersion of gold, iron & sulphur in water. They cannot be prepared directly they are prepared by special method only. They are easily precipitated by adding small amount of electrolyte.
lyophilic sol :
They are those solution in which the dispersed phase exhibits a definite affinity for the dispersion medium(liquid) or the solvent.For eg. Dispersion of starch, gum, & protein in water.They cen be easily prepared by directly mixing with liquid dispersion medium. They are quite stable and and not easily precipitated.
