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.

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.

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.
