	CWSF Project Summary - Energy Solution
		However, in testing copper (I) chloride, made by electrolyzing hydrochloric acid with copper electrodes, a voltage was noticed when bright light preferentially illuminated one of two copper electrodes in a beaker.
		Hydrochloric acid, sodium chloride, ammonium chloride, copper (II) chloride, lithium bromide or ammonium bromide sufficed for this purpose.
		The principle of operation of the copper chloride / ammonium chloride thermocell was deduced from observations made during the solution identification phase of the research, augmented by thermal and electrical analysis data, and by data found in the literature.

	Method and apparatus for regeneration of a copper-containing etching solution - Patent 4508599
		The chloride ions in the spent etching solution are oxidized at the anode to produce chlorine which reacts with copper (I) chloride to form copper (II) chloride.
		The chloride ions are obtained from the reaction at the cathode wherein copper (I) chloride and copper (II) chloride is reduced to metallic copper.
		At the anode, chloride ions are oxidized to form chlorine, which readily dissolves in water and is quickly distributed through the entire container of the regeneration apparatus by the generation of a strong flow of electrolyte.

	Copper Chloride Experiment
		It is not possible to collect iron(III) chloride because that will remain in solution as Fe(3+) and Cl(-) ions --the combination of these ions do not form a precipitate.
		An old bottle of "Copper Chloride" crystals with a poor label might not validate an assumption that it is in the (II) state.
		Then Cu(I) chloride would be cleanly converted to Cu(II) chloride by shaking with air or by standing a long time.

	NPI: Copper and compounds fact sheet
		Copper (II) chloride is used as a catalyst for organic and inorganic reactions, mordant for dyeing and printing textiles, pigment for glass and ceramics, wood preservative, disinfectant, insecticide, fungicide, and herbicide, and as a catalyst in the production of chlorine from hydrogen chloride.
		It is also used in the petroleum industry as a purifying agent, in the manufacture of indelible, invisible, and laundry marking inks, in metallurgy to recover mercury from ores, in refining copper, silver and gold, in tinting baths for iron and tin, in photography, in pyrotechnics, and to remove lead compounds from petrol and oils.

	Copper(I) chloride - Wikipedia, the free encyclopedia
		It is a Lewis acid which reacts with suitable ligands such as ammonia or chloride ion to form complexes, many of which are water-soluble.
		Copper(I) chloride is a Lewis acid, classified as soft according to the Hard-Soft Acid-Base concept.

	Reaction of Chlorine with Copper
		The copper reacts vigorously with the chlorine to form a cloud of copper(II) chloride.
		When the flask is rinsed with water the copper(II) chloride dissolves forming a blue-green solution.
		The copper is seen to be oxidized all the way to copper(II) chloride because the product, when dissolved in water, has the blue-green color characteristic of aqueous copper(II) chloride.

	copper
		The chemistry of copper(II) is mainly summarised from elsewhere on the site, with links available to more detailed explanations.
		Copper(II) ions oxidise iodide ions to iodine, and in the process are themselves reduced to copper(I) iodide.
		But in the presence of excess chloride ions from the HCl, this reacts to give a stable, soluble copper(I) complex.

		All crystals of sodium chloride are cubes (okay, there are a few rare twinned cubes and other defects but they can be explained as variations on cubical crystals) and have the same density and the same refractive index.
		When copper chloride is dissolved in the minimum amount of water it forms a brown green solution.
		The copper chlorides begin to form a sort of inorganic polymer, as shown here (L represents a generalized ligand, which can be water (or as we will see later) other things).

		Pure copper (I) chloride is a white compound.
		(Copper (I) chloride is fairly stable in solution because it is insoluble in water.) Any homemade sample of copper (I) chloride will be contaminated with fairly large amounts of copper (II) oxychloride and copper (II) chloride due to aerial oxidation.
