Aluminium Chloride

Aluminium Chloride Hexahydrate or Aluminum Chloride Hexahydrate Specifications of Aluminum Chloride Hexahydrate or Aluminum Chloride Hexahydrate Commercial Pure Aluminum Chloride Hexahydrate Grade 1 AlCl3·6H2O 241.43 Aluminum chloride, hexahydrate. Aluminum chloride hexahydrate [7784-13-6]. Assay: 98% minimum AlCl3 on dry basis. Water: between 42.0% and 48.0%. Sulfate— The addition of 0.2 mL of barium chloride TS to 10 mL of a solution (1 in 100) produces no turbidity within 1 minute. Limit of alkalies and alkaline earths— To a boiling solution of 1.0 g in 150 mL of water add a few drops of methyl red TS, then add 6 N ammonium hydroxide until the color of the solution just changes to a distinct yellow. Add hot water to restore the volume to 150 mL, and filter while hot. Evaporate 75 mL of the filtrate to dryness, and ignite to constant weight: the weight of the residue does not exceed 2.5 mg (0.5%). Heavy metals, Method — the limit is 0.002%. Iron — 0.001%. Aluminum Chloride Hexahydrate Grade 2 AlCl3·6H2O 241.43 Aluminum chloride, hexahydrate. Aluminum chloride hexahydrate [7784-13-6]. Assay: 95.5% minimum on dry basis Fe: 0.025% max Water insoluble: 0.1% max Pb: 0.0005% max Aluminium Chloride Hexahydrate BP Grade Ph Eur AlCl3,6H2O -- 241.4 -- 7784-13-6 DEFINITION Content: 95.0 per cent to 101.0 per cent. CHARACTERS Appearance: White or slightly yellow, crystalline powder or colourless crystals, deliquescent. Solubility: Very soluble in water, freely soluble in ethanol (96 per cent), soluble in glycerol. IDENTIFICATION A. Dilute 0.1 ml of solution S2 (see Tests) to 2 ml with water. The solution gives reaction of chlorides. B. Dilute 0.3 ml of solution S2 to 2 ml with water. The solution gives the reaction of aluminium. TESTS Solution S1: Dissolve 10.0 g in distilled water and dilute to 100 ml with the same solvent. Solution S2: Dilute 50 ml of solution S1 to 100 ml with wat...
