Copper(II) hydroxide is the hydroxide of copper with the chemical formula of Cu(OH) 2. It is a pale greenish blue or bluish green solid. Some forms of copper(II) hydroxide are sold as "stabilized" copper(II) hydroxide, although they likely consist of a mixture of copper(II) carbonate and hydroxide. Cupric hydroxide is a strong base, although ...
Copper(I) hydroxide would also be expect to easily oxidise to copper(II) hydroxide: 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.
Adding aqueous sodium hydroxide causes the precipitation of light blue solid copper(II) hydroxide. A simplified equation is: 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
Spertiniite is a rare copper hydroxide mineral. 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. [3]
Basic copper carbonate is a chemical compound, more properly called copper(II) carbonate hydroxide. It can be classified as a coordination polymer or a salt. It consists of copper(II) bonded to carbonate and hydroxide with formula Cu 2 (CO 3)(OH) 2. It is a green solid that occurs in nature as the mineral malachite.
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.
The following equation is an example, where M represents the given metal: MCO 3 → MO + CO 2. A specific example is that involving calcium carbonate: CaCO 3 → CaO + CO 2. Metal chlorates also decompose when heated. In this type of decomposition reaction, a metal chloride and oxygen gas are the products.
