Cupric Chloride USP Grade

CuCl2-2H2O -- 170.48
Copper chloride (CuCl2) dihydrate.
Copper(2+) chloride dihydrate [10125-13-0].
Anhydrous 134.45 [7447-39-4].
Cupric Chloride contains not less than 99.0 percent and not more than 100.5 percent of CuCl2, calculated on the dried basis.
Identification: A solution (1 in 20) responds to the tests for Chloride and for Copper.
Loss on drying: Dry it at 105 for 16 hours: it loses between 20.9% and 21.4% of its weight.
Insoluble matter: Transfer 10 g to a 250-mL beaker, add 100 mL of water and 2 mL of hydrochloric acid, cover the beaker, and heat to boiling. Digest the hot solution on a steam bath for 1 hour, and filter through a tared, fine-porosity filtering crucible. Rinse the beaker with hot water, passing the rinsings through the filter, and finally wash the filter with additional hot water. Dry the filter at 105C, the residue weighs not more than 1.0 mg (0.01%).
Sulfate: (0.005%).
Limit of sodium: The limit is 0.02%.
Limit of potassium: The limit is 0.01%.
Limit of calcium: The limit is 0.005%.
Limit of iron: The limit is 0.005%.
Limit of nickel: The limit is 0.01%.
