Sodium Bromide
CAS Number: 7647-15-6
Molecular Formula: NaBr
Molecular Weight: 102.91
Sodium Bromide
Sodium Bromide USP Grade
NaBr --- 102.89 --- CAS 7647-15-6
Sodium Bromide contains not less than 98.0 percent and not more than 100.5 percent of NaBr, 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 4.0 mg of sodium bromide responds to the test for Bromide.
B: It responds to the test for Sodium.
Acidity or alkalinity: To 10 mL of the solution prepared for the test for Appearance of solution, add 0.1 mL of bromothymol blue: 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 3.0% of its weight.
Bromates:
Starch mercuric iodide solution: Triturate 1.0 g of soluble starch with 5 mL of water, and pour the mixture into 100 mL of boiling water containing 10 mg of mercuric iodide.
Procedure: To 10 mL of the solution prepared for the test for Appearance of solution add 1 mL of Starch-mercuric iodide solution, 0.1 mL of a 100 g per L solution of potassium iodide, and 0.25 mL of 0.5 M sulfuric acid. Allow to stand protected from light for 5 minutes. No blue or violet color develops.
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: To pass the test. (0.02%, calculated as Ca).
Heavy metals: not more than 10 ppm.
