Compounds are divided at the outset into two main groups according to their solubility in water. Each of these groups is then subdivided by the use of the other solvents. The water-soluble compounds are divided into two classes : Those soluble in ether (group 51) and those insoluble in ether (group 52). By use of 5% sodium hydroxide solution and 5% hydrochloric acid, the compounds of the water insoluble group are subdivided into three categories : acidic, basic and neutral compounds. The acidic compounds are separated into two classes (Group Al and A 2) by reference to their solubilities in sodium bicarbonate solution.

Thus, first test the presence of nitrogen as an element in the mixture. If nitrogen is present then perform the following experiment: Treat 500 mg of the mixture with 5 ml of 1 : 1 HCl in a test tube. Shake well and filter or separate two layers I Filtrate (aqueous layer) Residue or non-aqueous layer Cool the aqueous layer (filtrate) in an ice bath and add cold 10% NaOH solution dropwise till the solution becomes alkaline. Cool the resulting alkaline solution in an ice bath. (i) Appearance of solid: This indicates that basic component is present in the mixture which is in the form of solid or (ii) Appearance of emulsion : This indicates that basic component is present in the mixture as a non-volatile liquid.
