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 ...
Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 (OH) 2.This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.
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] Ball-and-stick model of the complex [Cu(NH 3) 4 (H 2 O) 2 ...
A green layer of verdigris (copper carbonate) can often be seen on old copper structures, such as the roofing of many older buildings [21] and the Statue of Liberty. [22] Copper tarnishes when exposed to some sulfur compounds, with which it reacts to form various copper sulfides. [23]
The molybdenite occurrence shown in Figure 1 in the southern part of the main chargeability anomaly at Silverback, and the porphyry unit with gold-bearing quartz-carbonate veins located to the west (see Photo 1 of NR24- dated October 24 th) serve as important building blocks for this evolving, integrated model for a large, polymetallic copper ...
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 ...
