Copper(II) chloride is used as a mordant in the textile industry, petroleum sweetener, wood preservative, and water cleaner. [8] [28] Copper(II) chloride is also used in high school demos, such as reacting with aluminum to create aluminum chloride and copper, and learning how to measure moles. [29]
Aluminium chloride may be formed via a single displacement reaction between copper(II) chloride and aluminium. 2 Al + 3 CuCl 2 → 2 AlCl 3 + 3 Cu In the US in 1993, approximately 21,000 tons were produced, not counting the amounts consumed in the production of aluminium.

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.
Iron(III) chloride is produced commercially by oxychlorination (and other methods). For example, dissolution of iron ores in hydrochloric acid gives a mixture of ferrous and ferric chlorides: [4] Fe 3 O 4 + 8 HCl → FeCl 2 + 2 FeCl 3 + 4 H 2 O. The iron(II) chloride is converted to the iron(III) derivative by treatment with oxygen and ...
In the processing of cellulose, the copper ammine complex known as Schweizer's reagent ([Cu(NH 3) 4 (H 2 O) 2](OH) 2) is sometimes used to solubilise the polymer. Schweizer's reagent is prepared by treating an aqueous solutions of copper(II) ions with ammonia. Initially, the light blue hydroxide precipitates only to redissolve upon addition of ...
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).
The flame test carried out on a copper halide. The characteristic bluish-green color of the flame is due to the copper. A flame test is relatively quick test for the presence of some elements in a sample. The technique is archaic and of questionable reliability, but once was a component of qualitative inorganic analysis.
