Aluminium Chloride Hexahydrate
Aluminium Chloride Hexahydrate:
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 water.
Appearance of solution: Solution S2 is clear and not more intensely coloured than reference
solution.
Sulphates: Maximum 100 ppm, determined on solution S1.
Iron: Maximum 10 ppm, determined on solution S1.
Alkali and alkaline-earth metals: Maximum 0.5 per cent.
Heavy metals: Maximum 20 ppm.
Water: 42.0 per cent to 48.0 per cent, determined on 50.0 mg.
ASSAY
Dissolve 0.500 g in 25.0 ml of water. Carry out the complexometric titration of aluminium. Titrate
with 0.1 M zinc sulphate until the colour of the indicator changes from greyishgreen to pink. Carry
out a blank titration. 1 ml of 0.1 M sodium edetate is equivalent to 24.14 mg of AlCl3,6H2O.
STORAGE
In a well-filled, airtight container , protected from light, at a temperature not exceeding 25C.
Aluminum Chloride USP Grade
AlCl3·6H2O -- 241.43 -- [7784-13-6].
Solubility in 70 percent alcohol: One volume dissolves in 3 volumes of 70 percent alcohol, with not
more than slight opalescence.
Aluminum Chloride contains not less than 95.0 percent and not more than 102.0 percent of AlCl3,
calculated on the anhydrous basis.
Identification: A solution (1 in 10) responds to the tests for Aluminum and for Chloride.
Water: Between 42.0% and 48.0%.
Sulfate: The addition of 0.2 mL of barium chloride to 10 mL of a solution (1 in 100) produces no
turbidity within 1 minute.
Limit of alkalies and alkaline earths: the limit is 0.5%.
Heavy metals: the limit is 0.002%.
Iron: the limit is 0.001%.
