Answer» Correct Answer - 3 Colloidal solution of gold is obtained when dispersed phase is solid and dispersion medium is liquid. Substances like methals cannot be brought into the colloidal state simply by bringing them in contact with water and therefore, special methods are devised for the purpose. Hence, they are known as hydrophobic or lyophobic colloids. |
