The main use of copper(I) chloride is as a precursor to the fungicide copper oxychloride. For this purpose aqueous copper(I) chloride is generated by comproportionation and then air-oxidized: [12] Cu + CuCl 2 → 2 CuCl 4 CuCl + O 2 + 2 H 2 O → Cu 3 Cl 2 (OH) 4 + CuCl 2. Copper(I) chloride catalyzes a variety of organic reactions, as
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]

The Statue of Liberty, showing advanced patination; verdigris is responsible for the statue's iconic green colour.. Verdigris (/ ˈ v ɜːr d ɪ ɡ r iː (s)/) [1] is a common name for any of a variety of somewhat toxic [2] [3] [4] copper salts of acetic acid, which range in colour from green to a bluish-green depending on their chemical composition.
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).
Bronze disease is the chloride corrosion of cuprous (copper-based) artifacts. It was originally thought to be caused by bacteria. [1] It is contagious in that the chlorides which cause it can spread the condition if they are brought into contact with another cuprous object.
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 ...
