|#||Lyophilic Sol (solvent loving):||Lyophobic sol (solvent hating):|
|1||Lyophilic colloids pass into the colloidal form readily when brought in contact with solvent.||Lyophobic colloids do not form, the colloidal solutions easily when treated with solvent.|
|2||They are called, the reversible sols because they can be recovered from the colloidal solutions and can be converted into the colloidal form when desired.||They are called irreversible sols because they can not be recovered from their colloidal form.|
|3||Small quantities of electrolytes do not effect precipitation, but only large quantities of electrolytes cause precipitation.||Even small quantities of the electrolytes can cause precipitation.|
|4||The particles are not easily detected in the ultra-microscope.||The particles are easily detected by an ultra-microscope.|
|5||The particles may or may not migrate an electric field. The migration may be in any direction.||Particles migrate only in one direction.|
|6||Substances like starch, proteins, gums, soaps, and metasilicic acid are common.||Colloids of metals (Au, Pt), sulphur, arsenius sulphide and silver iodide are common examples.|
