Potassium Bromide USP BP Ph Eur Analytical Reagent Manufactures

CAS No.: 7758-02-3, EC Code EINECS: 231-830-3, Molecular Weight: 119, Chemical Formula: KBr

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.
Test solution: Dissolve 10.0 g in carbon dioxide-free water, and dilute with the same solvent to 100 mL.
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 pass the test..
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.
