Cupric Chloride Dihydrate, also known as Copper(2+) Chloride Dihydrate, Copper Dichloride Dihydrate, Copper Bichloride Dihydrate, and Coppertrac, has the chemical formula CuCl2-2H2O or Cl2CuH4O2. In anhydrous form, it appears as a yellowish-brown crystalline solid. Whereas, the dihydrate appears as a green crystalline powder with no odor and occurs naturally as the mineral eriochalcite. It is soluble in Water, Alcohol, and Acetone at ambient conditions. When heated to decomposition, it emits toxic fumes of Hydrogen Chloride gas and Copper Oxides. It can be produced either by the reaction of Copper with Chlorine or by combining Copper Carbonate with Hydrochloric Acid. Chemicals in the Reagent Grade category have high purity and are best suited for analytical purposes. They're useful in research investigations as they produce consistent, trustworthy, and repeatable findings.
