Specifications of Commercial Pure Potassium Bromide
Assay: 99.0% KBr
pH of a 5% solution: 4.5.0-9 at 25C
Insoluble matter: 0.05%
Loss on drying: 0.5% max
Chloride: 0.5% max

Potassium Bromide contains not less than 98.0 percent and not more than 100.5 percent of KBr, calculated on the dried basis. It contains no added substances.

Appearance of solution: clear and colorless.
Identification:
A: A solution containing 4.5 mg of potassium bromide responds to the test for Bromide.
B: Responds to the test for Potassium.
Acidity or alkalinity: To 10 mL of the solution prepared for the test for Appearance of solution, add 0.1 mL of bromothymol blue TS: not more than 0.5 mL of 0.01 N hydrochloric acid or 0.01 N sodium hydroxide is required to change the color of this solution.
Loss on drying: Dry it at 100 to 105 for 3 hours: it loses not more than 1.0% of its weight.
Bromates: To pass the test.
Limit of chlorine: not more than 0.6%.
Iodides: To 5 mL of the solution prepared for the test for Appearance of solution add 0.15 mL of a 10.5 g per 100 mL ferric chloride solution, and 2 mL of dichloromethane. Shake, and allow to separate. The lower layer is colorless.
Sulfates: A 2.0-g portion shows no more sulfate than corresponds to 0.2 mL of 0.020 N sulfuric acid (0.01%).
Limit of iron: not more than 20 ppm.
Magnesium and alkaline-earth metals: (0.02%, calculated as Ca).
Heavy metals: not more than 10 ppm.

CHARACTERS
Appearance: White or almost white, crystalline powder or colourless crystals.
Solubility: Freely soluble in water and in glycerol, slightly soluble in alcohol.

IDENTIFICATION
A. It gives reaction of bromides.
B. Solution S (see Tests) gives the reactions of potassium.

TESTS
Solution S: Dissolve 10.0 g in carbon dioxide-free water R prepared from distilled water R 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 0.1 ml of bromothymol blue solution R1. 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 R, 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 105C for 3h.

Potassium Bromate n Potassium Bromide Suppliers:

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
