  2. Copper(II) carbonate - Wikipedia

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

    3, such as mixing solutions of copper(II) sulfate CuSO 4 and sodium carbonate in ambient conditions, yield instead a basic carbonate and CO 2, due to the great affinity of the Cu 2+ ion for the hydroxide anion HO −. [5] Thermal decomposition of the basic carbonate at atmospheric pressure yields copper(II) oxide rather than the carbonate.

  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. 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 ...

    In aqueous solution, copper(II) exists as [Cu(H 2 O) 6] 2+. This complex exhibits the fastest water exchange rate (speed of water ligands attaching and detaching) for any transition metal aquo complex. Adding aqueous sodium hydroxide causes the precipitation of light blue solid copper(II) hydroxide. A simplified equation is:

    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

    Malachite, a common ore of copper is primarily copper carbonate hydroxide Cu 2 (CO 3)(OH) 2. [2] This mineral undergoes thermal decomposition to 2CuO, CO 2, and H 2 O [3] in several stages between 250 °C and 350 °C.

  8. 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]

    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).
