Heavy Bismuth Subnitrate BP
Ph Eur
4[BiNO3(OH)2],BiO(OH) -- 1462 -- 1304-85-4
DEFINITION
Content: 71.0 per cent to 74.0 per cent of Bi (Ar 209.0) (dried substance).
CHARACTERS
Appearance: White or almost white powder.
Solubility: Practically insoluble in water and in ethanol (96 per cent). It dissolves in mineral acids with decomposition.
IDENTIFICATION
A. Dilute 1 ml of solution S1 (see Tests) to 5 ml with water and add 0.3 ml of potassium iodide solution. A black precipitate is formed which dissolves into an orange solution with the addition of 2 ml of potassium iodide solution.
B. It gives reaction (b) of bismuth.
C. It gives the reaction of nitrates.
D. pH: maximum 2.0 for solution S2 (see Tests).
TESTS
Solution S1: Shake 5.0 g by gently heating in 10 ml of water and add 20 ml of nitric acid. Heat until dissolution, cool and dilute to 100 ml with water.
Solution S2: Place 1.00 g in a 20 ml volumetric flask and add 2.0 ml of lead-free nitric acid. Allow acid attack to take place without heating and if necessary warm slightly at the end to completely dissolve the test sample. Add 10 ml of water, shake and add, in small fractions, 4.5 ml of lead-free ammonia; shake and allow to cool. Dilute to 20.0 ml with water, shake again is required to change the colour of the indicator to pink.
Chlorides: Maximum 200 ppm.
Copper: Maximum 50.0 ppm.
Lead: Maximum 20.0 ppm.
Silver: Maximum 25.0 ppm.
Substances not precipitated by ammonia: Maximum 1.0 per cent.
To 20 ml of solution S1, add concentrated ammonia until an alkaline reaction is produced and filter. Wash the residue with water and evaporate the combined filtrate and washings to dryness on a water-bath. To the residue, add 0.3 ml of dilute sulphuric acid R and ignite.
The residue weighs a maximum of 10 mg.
Loss on drying: Maximum 3.0 per cent, determined on 1.000 g by drying in an oven at 105C.
ASSAY: Dissolve with heating 0.250 g in 10 ml of a mixture of 2 volumes of perchloric acid and 5 volumes of water. To the hot solution, add 200 ml of water and 50 mg of xylenol orange triturate. Titrate with 0.1 M sodium edetate until a yellow colour is obtained.
1 ml of 0.1 M sodium edetate is equivalent to 20.90 mg of Bi.

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
