PotassiumAlum USP
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 [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.

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.

Barter

They who love thee on this earth, keep calling on thee and chanting thy beads
Lest thou forgetest.

They assign the credit of their hard work to your blessings
They keep you amused.

They come to thy temple with baskets of fruits, as if you were a glutton
They deny the same to their children.

They offer you milk for a bath and burn the ghee
They hardly understand the meaning of it.

They bring gold and diamonds. They come with beating of drums
They love to advertise their offerings.

They offer you a small bribe as advance for booty, called lottery
They love to dream.

I do not bow down at your door
I do not bargain for booty
Your promise of the heaven does not lure me
Your hell-fire does not scare me
I do not even know the proper method of prayer
I do not offer any thing to you
Ages have gone by and I have not seen you my lord
Yet my love for you keeps waiting for you
