CHARACTERS Appearance: White or almost white, crystalline powder or colourless crystals, efflorescent in air. Solubility: Freely soluble in water (the solution becomes cloudy after standing or on dilution), freely soluble in ethanol (96 per cent). It dissolves in dilute hydrochloric acid. IDENTIFICATION A. To 1 mL of solution S1 (see Tests) add 5 mL of water and 0.05 mL of mercuric chloride solution. A blackish-grey precipitate is formed. B. Dissolve 1.0 g in 3.0 ;mL of water. Add 0.5 mL of dilute sodium hydroxide solution to the cloudy solution; a yellowish flocculent precipitate is formed. Add 6.5 mL of water. To 1.0 mL of the previously shaken suspension add 1.0 mL of strong sodium hydroxide solution; the precipitate dissolves and the resulting solution is clear and colourless. C. Dissolve 10 mg in 2 mL of dilute nitric acid. The solution gives reaction (a) of chlorides. TESTS Solution S1: To 0.40 g add 1 mL of dilute hydrochloric acid and dilute to 20 mL with distilled water. Solution S2: Dissolve 1.0 g in dilute hydrochloric acid and dilute to 30 mL with the same acid. Heat to boiling. Add 30 mL of thioacetamide solution and boil for 15 min (solution A). Take 5 mL, filter and heat the filtrate to boiling. Add 5 mL of thioacetamide solution and boil for 15 min. If a precipitate is formed, add the remainder of solution A (solution A') to the mixture. Add 10 mL of thioacetamide solution and boil. Repeat the series of operations from “Take 5 mL” until a precipitate is no longer formed on addition of thioacetamide solution to the filtrate obtained from the 5 mL of solution A (solution A', solution A', etc. respectively). If no precipitate is formed or if no more precipitate is formed combine the solution obtained with the remainder of solution A (solution A', solution A', etc. respectively), filter and wash the precipitate with 10 mL of water. Heat the filtrate until the resulting vapour no longer turns a moistened piece of lead acetate paper blackish-grey. Allow to cool and dilute to 50 mL with water. Appearance of solution: The solution is clear and colourless. Dissolve 10.0 g in dilute hydrochloric acid and dilute to 20 mL with the same acid. Substances not precipitated by thioacetamide: Maximum 0.2 per cent. Evaporate 25 mL of solution S2 to dryness and ignite at 600±50C. The residue weighs a maximum of 1 mg. Sulfates: Maximum 500 ppm, determined on solution S1. Iron: Maximum 100 ppm. Dilute 5 mL of solution S2 to 10 mL with water.
