Ammonium Bromide BP Ph Eur
NH4Br - 97.9 - CAS 12124-97-9
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.

A jackal woke up early in the morning and went in to the plains. He looked at his long shadow in the rising morning sun and said to himself, "I must have a camel for my meal today".
He kept moving around till noon and it was getting hot and the jackal was tired. He was also hungry and thirsty. He looked at his small shadow in the mid-day sun. He murmered, "I was only joking about the camel, a mouse will do".
