Specifications of Arsenious Trioxide BP Ph Eur Grade for Homoeopathic Preparations:
As2O3 --- 197.8 --- CAS 1327-53-3
DEFINITION
Content: 99.5 per cent to 100.5 per cent of As2O3.
CHARACTERS
Appearance: White or almost white powder.
Solubility: Practically insoluble to sparingly soluble in water. It dissolves in solutions of alkali hydroxides and carbonates.
IDENTIFICATION
A. Dissolve 20 mg in 1 mL of dilute hydrochloric acid, add 4 mL of water and 0.1 mL of sodium sulfide solution. The resulting yellow precipitate is soluble in dilute ammonia.
B. Dissolve 20 mg in 1 mL of hydrochloric acid, add 5 mL of hypophosphorous reagent and heat for 15 min on a water-bath. A black precipitate develops.
TESTS
Appearance of solution: A 100 g/L solution in dilute ammonia is clear and colourless.
Sulfides: Maximum 20 ppm.
ASSAY
Dissolve 40.0 mg in a mixture of 10 mL of water and 10 mL of dilute sodium hydroxide solution. Add 10 mL of dilute hydrochloric acid and 3 g of sodium hydrogen carbonate and mix. Add 1 mL of starch solution and titrate with 0.05 M iodine.
1 mL of 0.05 M iodine is equivalent to 4.946 mg of As2O3.

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
