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 − .
The same hydrochloric acid solutions also react with acetylene gas to form [CuCl(C 2 H 2)]. Ammoniacal solutions of CuCl react with acetylenes to form the explosive copper(I) acetylide, Cu 2 C 2. Alkene complexes of CuCl can be prepared by reduction of CuCl 2 by sulfur dioxide in the presence of the alkene in alcohol solution.

Copper(II) acetate, also referred to as cupric acetate, is the chemical compound with the formula Cu(OAc) 2 where AcO − is acetate (CH 3 CO − 2).The hydrated derivative, Cu 2 (OAc) 4 (H 2 O) 2, which contains one molecule of water for each copper atom, is available commercially.
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 ...
Legend: (g)—gas; (l)—liquid; (aq)—aqueous solution; the balance of the species are in a solid phase. Atomic Energy of Canada Limited has demonstrated experimentally a CuCl electrolyzer in which hydrogen is produced electrolytically at the cathode and Cu(I) is oxidized to Cu(II) at the anode, thereby combining above steps 1 and 4 to ...
Its chemical name is 1-(4-sulfo-1-napthylazo)-2-napthol-6,8-disulfonic acid, trisodium salt. Ponceau (17th century French for " poppy-coloured ") is the generic name for a family of azo dyes . Ponceau 4R is a strawberry red azo dye which can be used in a variety of food products, and is usually synthesized from aromatic hydrocarbons ; it is ...
