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.

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 ferrocyanide TS to 20 mL of a solution (1 in 150): no blue color is produced immediately.

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 25C 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%.

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.
