Copper(II) chloride, also known as cupric chloride, is an inorganic compound with the chemical formula Cu Cl 2. The monoclinic yellowish-brown anhydrous form slowly absorbs moisture to form the orthorhombic blue-green dihydrate CuCl 2 ·2H 2 O , with two water molecules of hydration .
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).
Copper(I) chloride is produced industrially by the direct combination of copper metal and chlorine at 450–900 °C: [11] [12] 2 Cu + Cl 2 → 2 CuCl Copper(I) chloride can also be prepared by reducing copper(II) chloride with sulfur dioxide , or with ascorbic acid ( vitamin C ) that acts as a reducing sugar : [ 13 ] [ 14 ]
