Aqueous solutions prepared from copper(II) chloride contain a range of copper(II) complexes depending on concentration, temperature, and the presence of additional chloride ions. These species include the blue color of [Cu(H 2 O) 6 ] 2+ and the yellow or red color of the halide complexes of the formula [CuCl 2+ x ] x − .
For example H 3 O + CuCl 2 − forms in concentrated hydrochloric acid. [15] Chloride is displaced by CN − and S 2 O 3 2−. [12] Solutions of CuCl in HCl absorb carbon monoxide to form colourless complexes such as the chloride-bridged dimer [CuCl(CO)] 2. The same hydrochloric acid solutions also react with acetylene gas to form [CuCl(C 2 H 2)].
Division 4.1: Flammable Solid . Flammable solids are any of the following four types of materials: Desensitized Explosives: explosives that, when dry, are Explosives of Class 1 other than those of compatibility group A, which are wetted with sufficient water, alcohol, or plasticizer to suppress explosive properties; and are specifically authorized by name either in the 49CFR 172.101 Table or ...

Cu 2 (OH) 3 Cl can be prepared by air oxidation of CuCl in brine solution. The CuCl solution is usually made by the reduction of CuCl 2 solutions over copper metal. A CuCl 2 solution with concentrated brine is contacted with copper metal until the Cu(II) is completely reduced. The resulting CuCl is then heated to 60–90 °C (140–194 °F) and ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
