The mineral of the formula Cu(OH) 2 is called spertiniite. Copper(II) hydroxide is rarely found as an uncombined mineral because it slowly reacts with carbon dioxide from the atmosphere to form a basic copper(II) carbonate. Thus copper(II) hydroxide slowly acquires a dull green coating in moist air by the reaction: 2 Cu(OH) 2 + CO 2 → Cu 2 CO ...
Chemically, it is copper(II) hydroxide with the formula Cu(OH) 2. It occurs as blue to blue-green tabular orthorhombic crystal aggregates in a secondary alkaline environment altering chalcocite . Associated minerals include chalcocite, atacamite , native copper , diopside , grossular , and vesuvianite .
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).
Pourbaix diagram for copper in uncomplexed media (anions other than OH − not considered). Ion concentration 0.001 m (mol/kg water). Temperature 25 °C. Cu 2+ + 2 OH − → Cu(OH) 2. Aqueous ammonia results in the same precipitate. Upon adding excess ammonia, the precipitate dissolves, forming tetraamminecopper(II): Cu(H 2 O) 4 (OH) 2 + 4 NH ...
4CuOH + 2 H 2 O + O 2 → 4Cu(OH) 2. It would also be expected to rapidly dehydrate: 2CuOH → Cu 2 O + H 2 O. Solid CuOH would be of interest as a possible intermediate in the formation of copper(I) oxide (Cu 2 O), which has diverse applications. [3] e.g.forapplications for use in solar cells. [4]

The formula, Cu 2 CO 3 (OH) 2 shows that it is halfway between copper carbonate and copper hydroxide. Indeed, in the past the formula was written as CuCO 3 ·Cu(OH) 2. The crystal structure is made up of copper, carbonate and hydroxide ions. [37] The mineral atacamite is an example of a basic chloride. It has the formula, Cu 2 Cl(OH) 3.
