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.
Copper(II) carbonate or cupric carbonate is a chemical compound with formula CuCO 3. At ambient temperatures, it is an ionic solid (a salt) consisting of copper(II) cations Cu 2+ and carbonate anions CO 2− 3. This compound is rarely encountered because it is difficult to prepare [2] and readily reacts with water moisture from the air.
Basic copper carbonate (the "copper carbonate" of commerce), actually a copper carbonate hydroxide; which may be either Cu 2 CO 3 (OH) 2: the green mineral malachite, verdigris, the pigment "green verditer" or "mountain green" Cu 3 (CO 3) 2 (OH) 2: the blue mineral azurite, and the pigment "blue verditer" or "mountain blue" Lapis armenus, a ...
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).
It can be formed by heating copper in air at around 300–800 °C: 2 Cu + O 2 → 2 CuO. For laboratory uses, copper(II) oxide is conveniently prepared by pyrolysis of copper(II) nitrate or basic copper(II) carbonate: [4] 2 Cu(NO 3) 2 → 2 CuO + 4 NO 2 + O 2 (180°C) Cu 2 (OH) 2 CO 3 → 2 CuO + CO 2 + H 2 O. Dehydration of cupric hydroxide ...
Like oxide, fluoride is a highly basic anion [19] and is known to stabilize metal ions in high oxidation states. Both copper(III) and even copper(IV) fluorides are known, K 3 CuF 6 and Cs 2 CuF 6, respectively. [1] Some copper proteins form oxo complexes, which also feature copper(III). [20]
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(II) acetate, also referred to as cupric acetate, is the chemical compound with the formula Cu(OAc) 2 where AcO − is acetate (CH 3 CO − 2).The hydrated derivative, Cu 2 (OAc) 4 (H 2 O) 2, which contains one molecule of water for each copper atom, is available commercially.
