CaCl2-2H2O -- 147.01

Assay— Calcium Chloride contains an amount of CaCl2 equivalent to not less than 99.0 percent and not more than 107.0 percent of CaCl2·2H2O.
Packaging and storage— Preserve in tight containers.
Labeling— Where Calcium Chloride is intended for use in hem dialysis, it is so labeled.
Identification— A solution (1 in 10) responds to the tests for Calcium and for Chloride.
pH: between 4.5 and 9.2, in a solution (1 in 20).
Aluminum (where it is labeled as intended for use in hem dialysis)— the limit is 1 4g per g.
Iron, aluminum, and phosphate— To a solution (1 in 20) add 2 drops of 3 N hydrochloric acid and 1 drop of phenolphthalein TS. Then add ammonium chloride–ammonium hydroxide TS, drop wise, until the solution is faintly pink, add 2 drops in excess, and heat the liquid to boiling: no turbidity or precipitate is produced.
Heavy metals— the limit is 0.001%.
Limit of magnesium and alkali salts— Dissolve 1 g in about 50 mL of water, add 500 mg of ammonium chloride, and proceed as directed in the test for Limit of magnesium and alkali salts under Calcium Carbonate, beginning with “heat the solution, and boil for 1 minute”: the weight of the residue does not exceed 5 mg (1.0%).

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 not more intensely colored than reference solution.
Acidity or alkalinity: To 10 ml of freshly prepared solution S add 0.1 ml of phenolphthalein solution. If the solution is red, not more than 0.2 ml of 0.01 M hydrochloric acid is required to discharge the color and if the solution is colorless, not more than 0.2 ml of 0.01 M sodium hydroxide is required to turn it red.
Sulphates: Maximum 300 ppm.
Aluminium: To 10 ml of solution S add 2 ml of ammonium chloride solution R and 1 ml of dilute ammonia and boil the solution. No turbidity or precipitate is formed.
If intended for use in the manufacture of dialysis solutions, the above test is replaced by the test for Aluminium maximum 1 ppm.
Barium: To 10 ml of solution S add 1 ml of calcium Sulphate solution R. After at least 15 min, any opalescence in the solution is not more intense than that in a mixture of 1 ml of distilled water and 10 ml of solution S.
Iron: Maximum 10 ppm, determined on solution S.
Magnesium and alkali metals: Maximum 0.5 per cent.
Heavy metals: Maximum 20 ppm.
