Copper(II) chloride is used as a catalyst in a variety of processes that produce chlorine by oxychlorination. The Deacon process takes place at about 400 to 450 °C in the presence of a copper chloride: [8] 4 HCl + O 2 → 2 Cl 2 + 2 H 2 O. Copper(II) chloride catalyzes the chlorination in the production of vinyl chloride and dichloromethane. [8]
IR absorption spectrum of copper(I) chloride. Copper(I) chloride, commonly called cuprous chloride, is the lower chloride of copper, with the formula CuCl. The substance is a white solid sparingly soluble in water, but very soluble in concentrated hydrochloric acid. Impure samples appear green due to the presence of copper(II) chloride (CuCl 2).
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).

A sequestrant forms chelate complexes with polyvalent metal ions, especially copper, iron and nickel. This can prevent the oxidation of the fats in the food. Sequestrants are therefore a type of preservative. The name comes from Latin and means "to withdraw from use" [citation needed]. Common sequestrants are: Calcium chloride (E509) Calcium ...
Copper chloride may refer to: Copper(I) chloride (cuprous chloride), CuCl, mineral name nantokite; Copper(II) chloride (cupric chloride), CuCl 2, mineral name ...

Copper pesticide is applied as a contact protective foliar spray, so it remains deposited on leaf surfaces. A small concentration of copper ions may be taken up by plants as essential nutrients. Copper foliar sprays are also applied to correct plant copper deficiency. [8] Excess absorbed copper ions can kill sensitive cells in copper sensitive ...
