  2. Copper(II) carbonate - Wikipedia

    en.wikipedia.org/wiki/Copper(II)_carbonate

    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.

  3. Basic copper carbonate - Wikipedia

    en.wikipedia.org/wiki/Basic_copper_carbonate

    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.

  4. Azurite - Wikipedia

    en.wikipedia.org/wiki/Azurite

    Azurite has the formula Cu 3 (CO 3) 2 (OH) 2, with the copper(II) cations linked to two different anions, carbonate and hydroxide. It is one of two relatively common basic copper(II) carbonate minerals, the other being bright green malachite. Aurichalcite is a rare basic carbonate of copper and zinc. [8]

    Many other oxyanions form complexes; these include copper(II) acetate, copper(II) nitrate, and copper(II) carbonate. Copper(II) sulfate forms a blue crystalline pentahydrate, the most familiar copper compound in the laboratory. It is used in a fungicide called the Bordeaux mixture. [3]

  6. Copper(II) hydroxide - Wikipedia

    en.wikipedia.org/wiki/Copper(II)_hydroxide

    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 ...

  7. Copper(II) oxide - Wikipedia

    en.wikipedia.org/wiki/Copper(II)_oxide

    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 ...

    en.wikipedia.org/wiki/Copper_carbonate

    Copper carbonate may refer to : Copper (II) compounds and minerals. Copper(II) carbonate proper, CuCO 3 (neutral copper carbonate): a rarely seen moisture-sensitive compound. Basic copper carbonate (the "copper carbonate" of commerce), actually a copper carbonate hydroxide; which may be either Cu 2 CO

  9. Copper(II) nitrate - Wikipedia

    en.wikipedia.org/wiki/Copper(II)_nitrate

    Copper(II) nitrate describes any member of the family of inorganic compounds with the formula Cu(NO 3) 2 (H 2 O) x. The hydrates are hygroscopic blue solids . Anhydrous copper nitrate forms blue-green crystals and sublimes in a vacuum at 150-200 °C.
