Aluminium Sulphate BP
Aluminium Sulphate BP
DEFINITION
Aluminium sulphate
contains not less than 51.0 per cent and not more than the equivalent of
59.0 percent of Al2(SO4)3. It contains a
variable quantity of water of crystallization.
CHARACTERS
Colourless, lustrous
crystals or crystalline masses, soluble in cold water, freely soluble in hot
water, practically insoluble in alcohol.
IDENTIFICATION
A.
Solution S (see Tests) gives reaction of sulphates.
B.
Solution S gives the reaction of aluminium.
TESTS
Solution S
Dissolve 2.5 g in
water
R and dilute to 50 ml with the same solvent.
Appearance of solution
Solution S is not more
opalescent than reference suspension III and is colourless.
pH
The pH of the solution is
2.5 to 4.0.
Alkali and
alkaline-earth metals
To 20 ml of solution S add
100 ml of water, heat and add 0.1 ml of methyl red solution.
Add dilute ammonia until the colour of the indicator changes to
yellow. Dilute to 150 ml with water, heat to boiling and filter.
Evaporate 75 ml of the filtrate to dryness on a water-bath and ignite. The
residue weighs not more than 2 mg (0.4 per cent).
Ammonium
0.4 ml of solution S
diluted to 14 ml with water complies with the limit test for
ammonium (500 ppm).
Iron
2 ml of solution S diluted
to 10 ml with water complies with the limit test for iron (100 ppm).
Heavy metals
Dilute 8 ml of solution S to 20 ml with
water.
12 ml of the solution complies with limit test A for heavy metals (50 ppm).

Anhydrous 342.16.
Aluminum Sulfate contains
not less than 54.0 percent and not more than 59.0 percent of Al2(SO4)3. It
contains a varying amount of water of crystallization.
Identification
A
solution (1 in 10) responds to the tests for Aluminum and for Sulfate.
pH:
not less than
2.9, in a solution (1 in 20).
Water: not less
than 41.0% and not more than 46.0%.
Heavy metals The
limit is 20 µg per g.
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 and then add 6 N ammonium hydroxide just until
the color of the solution 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: not more than 2 mg of
residue remains (0.4%).
Limit of ammonium
salts Heat 1 g with 10 mL of 1 N sodium hydroxide on a steam bath for 1
minute: the odor of ammonia is not perceptible.
Iron To 20 mL of a
solution (1 in 150) add 0.3 mL of potassium ferrocyanide TS: no blue color
is produced immediately.
Organic volatile impurities: meets the
requirements.

DESCRIPTION
Aluminum Sulfate occurs as
a white powder, as shining plates, or as crystalline fragments. It is
anhydrous or contains 18 molecules of water of crystallization. Because of
efflorescence, the hydrate may have a composition approximating the formula
Al2(SO4)3·14H2O. One gram of the hydrate dissolves in about 2 mL of water.
The anhydrous approaches the same solubility, but the rate of solution is so
slow that it initially appears to be relatively insoluble. The pH of a 1:20
aqueous solution is 2.9 or above.
REQUIREMENTS
Identification: A
1:10 aqueous solution gives positive tests for Aluminum and for Sulfate.
Assay Anhydrous: Not less than 99.5% of Al2(SO4)3, calculated on the
ignited basis.
Octadecahydrate: Not less than 99.5% and not more than 114.0% of
Al2(SO4)3·18H2O, corresponding to not more than approximately 101.7% of
Al2(SO4)3·14H2O.
Alkalies and Alkaline
Earths: Passes test (about 0.4%).
Ammonium Salts: Passes test.
Fluoride: Not more
than 0.003%.
Lead: Not more than
3 mg/kg.
Loss on Ignition
Anhydrous: Not more than 5%.
Note: This
Requirement does not apply to Al2(SO4)3·18H2O.
Selenium: Not more
than 0.003%.
