Magnesium Chloride contains not less than 98.0 percent and not more than 101.0 percent of MgCl2·6H2O.
Packaging and storage— Preserve in tight containers.
Labeling— Where the product is intended for use in hem dialysis, it is so labeled.
Identification— A solution (1 in 20) responds to the tests for Magnesium and for Chloride
pH: between 4.5 and 7.0, in a 1 in 20 solution in carbon dioxide-free water.
Insoluble matter— not more than 0.005% is found.
Sulfate — A 10-g portion shows no more sulfate than corresponds to 0.50 mL of 0.020 N sulfuric acid (0.005%).
Barium— Dissolve 1 g in 10 mL of water, and add 1 mL of 2 N sulfuric acid: no turbidity is produced within 2 hours.
Limit of calcium— the limit is 0.01%.
Potassium— Dissolve 5 g in 5 mL of water, and add 0.2 mL of sodium bitartrate TS: no turbidity is produced within 5 minutes.
