Sulfuric acid, aluminum
potassium salt (2:1:1), dodecahydrate.
Aluminum potassium sulfate
(1:1:2) dodecahydrate [7784-24-9].
Anhydrous 258.21 [10043-67-1].
Potassium Alum contains
not less than 99.0 percent and not more than 100.5 percent of AlK(SO4)2,
calculated on the dried basis.
Packaging and storage Preserve in tight containers, and store at room temperature.
Identification
A: Add 1 N sodium
hydroxide drop wise to a solution of it (1 in 20): a precipitate is formed
that dissolves in an excess of the reagent. Ammonia is not evolved (distinction from Ammonium Alum).
B: Hold it in a
non-luminous flame: a violet color is imparted to the flame.
C: Add 10 mL of
sodium bitartrate TS to 5 mL of a saturated solution of it: a white,
crystalline precipitate is formed within 30 minutes.
D: A solution (1 in
20) responds to the tests for Aluminum and for Sulfate.
Loss on drying Transfer 2.0 g, in a tarred porcelain crucible, to a muffle furnace at 200.
Increase the temperature to 400 , and dry at 400 to constant weight. Cool in
a desiccator, and weigh: it loses between 43.0% and 46.0% of its weight.
Heavy metalsthe
limit is 0.002%.
Iron Add 5 drops
of potassium ferrocyanide TS to 20 mL of a solution (1 in 150): no blue
color is produced immediately.

AlK(SO4)2·12H2O Formula wt
474.38
INS: 522 CAS: [7784-24-9]
DESCRIPTION
Aluminum Potassium Sulfate
occurs as large, transparent crystals or crystalline fragments, or as a
white crystalline powder. One gram dissolves in 7.5 mL of water at 25° and
in about 0.3 mL of boiling water. Its solutions are acid to litmus. It is
insoluble in alcohol, but is freely soluble in glycerin.
Function: Buffer;
neutralizing agent; firming agent.
REQUIREMENTS
Identification: A
1:20 aqueous solution gives positive tests for Aluminum, for Potassium, and for
Sulfate.
Assay: Not less than
99.5% and not more than 100.5% of AlK(SO4)2·12H2O.
Ammonium Salts: Passes test.
Fluoride: Not more
than 0.003%.
Lead: Not more than
3 mg/kg.
Selenium: Not more
than 0.003%.

DEFINITION
Content
99.0 per cent to 100.5 per
cent of AlK(SO4)2,12H2O.
CHARACTERS
Appearance
Granular powder or colourless,
transparent, crystalline masses.
Solubility
Freely soluble in water, very
soluble in boiling water, soluble in glycerol, practically insoluble in ethanol
(96 per cent).
IDENTIFICATION
A. Solution S (see Tests)
gives the reactions of sulphates.
B. Solution S gives the
reaction of aluminium.
C. Shake 10 ml of solution S
with 0.5 g of sodium bicarbonate R and filter. The filtrate gives reaction (a) of potassium.
