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.
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
clear
and colourless.
pH: 3.0 to 3.5.
Ammonium: Maximum
0.2 per cent.
Iron: Maximum 100 ppm.
Heavy metals: Maximum 20
ppm.

Aluminum Potassium Sulfate
USP
AlK(SO4)2·12H2O 474.39
Sulfuric acid, aluminum
potassium salt (2:1:1), dodecahydrate.
Aluminum potassium sulfate (1:1:2)
dodecahydrate [CAS 7784-24-9].
Anhydrous
258.21 [CAS 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
metals— the limit is 0.002%.
Iron—
Add 5 drops of potassium ferro-cyanide TS to
20 mL of a solution (1 in 150): no blue color is
produced immediately.
