NH4Br - 97.9 - CAS 12124-97-9
Ammonium Bromide
DEFINITION
Content
Ammonium Bromide 98.5 per cent to 100.5 per cent (dried substance).
CHARACTERS
Appearance
Ammonium Bromide is white or almost white, crystalline powder or colourless crystals, hygroscopic.
Solubility
Freely soluble in water, sparingly soluble in alcohol. It becomes yellow when exposed to light or air.
IDENTIFICATION
A. It gives reaction of bromides.
B. 10 ml of solution S (see Tests) gives the reaction of ammonium salts.
TESTS
Solution S
Dissolve 10.0 g in carbon dioxide-free water prepared from distilled water and dilute to 100 ml with the same solvent.
Appearance of solution
Solution S is clear and colourless.
Acidity or alkalinity
To 10 ml of solution S add 0.05 ml of methyl red solution. Not more than 0.5 ml of 0.01 M hydrochloric acid or 0.01 M sodium hydroxide is required to change the colour of the indicator.
Bromates
To 10 ml of solution S add 1 ml of starch solution, 0.1 ml of a 100 g/l solution of potassium iodide and 0.25 ml of 0.5 M sulphuric acid and allow to stand protected from light for 5 min. No blue or violet colour develops.
Chlorides
Maximum 0.6 per cent.
Iodides
To 5 ml of solution S add 0.15 ml of ferric chloride solution and 2 ml of methylene chloride. Shake and allow to separate. The lower layer is colourless.
Sulphates
Maximum 100 ppm.
Iron
Maximum 20 ppm.
Magnesium and alkaline-earth metals
Maximum 200 ppm, calculated as Ca
Heavy metals
Maximum 10 ppm.
Loss on drying
Maximum 1.0 per cent, determined on 1.000 g by drying in an oven at 100-105C
Sulphated ash
Maximum 0.1 per cent, determined on 1.0 g.

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.
