![]() For this reason, it cannot be used in fireworks to obtain blue flame.Ĭopper chloride can be purchased from chemical suppliers or online from eBay and Amazon. If the flame temperature is too high, it breaks down and gives a more greenish flame color. In the presence of oxygen, it can also oxidize phenols.Ĭopper(II) chloride burns at low temperature with a deep blue flame (or green, depending on impurities). It is also useful in organic synthesis because it can chlorinate the alpha position of carbonyls. Besides this, it is a moderate oxidizer and will also dissolve other reactive metals such as zinc and magnesium. If hydrochloric acid is added to an aqueous solution of copper(II) chloride, tetrachlorocupric acid is formed.Ĥ H + + 8 Cl - + 4 CuCl 2 - + O 2 → 4 CuCl 4 2- + 2 H 2OĬopper(II) chloride can oxidize and dissolve aluminium, owing to the formation of the tetrachlorocuprate ion. In the presence of excess chloride ions, copper chloride will form a greener colored acidic copper(II) chloride, in which the water ligands are substituted for chloride ions. The material normally exists as a brilliant turquoise powder, but thin, transparent, fragile crystals may be grown. ![]() Copper(II) chloride is hygroscopic and absorbs water in open air to form the dihydrate, which is a neutral tetracoordinate complex. ![]() Copper(II) chloride is a brown powder that turns red when molten. ![]()
