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.

Aluminum Potassium Sulfate, Potassium Alum FCC Food Grade, Potash Alum
AlK(SO4)2·12H2O Formula weight 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.

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.
