Answer 1

Answer:

Copper II Carbonate is also referred to as Cupric Carbonate. Further, it is essentially a chemical compound. The Copper II Carbonate Formula is CuCO 3. Further, it is an ionic solid compound which consists of copper (II) cations Cu2+ and carbonate anions CO2− 3. It is not that easy to be found because it is quite difficult to prepare.

Preparation

It is generally expected of reactions like mixing solutions of Copper II sulfate CuSO 4 and sodium carbonate Na 2CO 3 in ambient conditions to produce CuCO 3, but instead, it produces a basic carbonate and CO2 because of the great attraction of the Cu2+ ion for the hydroxide anion HO−

When the basic carbonate thermally decomposes at atmospheric pressure, it produces Copper (II) oxide CuO instead of the carbonate.

W. F. T. Pistorius in the year, 1960, claimed synthesis. He did so when he heated basic copper carbonate at 180 °C in an atmosphere containing carbon dioxide, CO 2(450 atm) and water (50 atm) up to 36 hours. The majority of these products came out to be well-crystallized malachite Cu 2CO 3(OH)2, however, there was also a small quantity of the rhombohedral substance in the result which was claimed as CuCO 3. But, it is important to note that this synthesis was actually not reproduced.

If we look at the origin, we will see that the reliable synthesis of true Copper (II) carbonate was testified for the first time in 1973 by Hartmut Ehrhardt and others. Thus, this compound was acquired in the form of gray powder.

It was after they heated basic copper carbonate in an atmosphere containing carbon dioxide (which we produce by decomposing silver oxalate Ag 2C2O 4) at 500 °C and 2 GPa (20,000 atm). The compound was said to have a monoclinic structure.

Answer 2

Answer:

The name most commonly refers to the compound with formula Cu

2CO

3(OH)2. It is a green crystalline solid that occurs in nature as the mineral malachite. It has been used since antiquity as a pigment, and it is still used as such in artist paints, sometimes called verditer, green bice, or mountain green.

Sometimes the name is used for Cu

3(CO

3)2(OH)2, a blue crystalline solid also known as the mineral azurite. It too has been used as pigment, sometimes under the name mountain blue or blue verditer.

Both malachite and azurite can be found in the verdigris patina that is found on weathered brass, bronze, and copper. The composition of the patina can vary, in a maritime environment depending on the environment a basic chloride may be present, in an urban environment basic sulfates may be present.[3]

This compound is often improperly called (even in chemistry articles) copper carbonate, cupric carbonate, and similar names. The true (neutral) copper(II) carbonate CuCO3 is not known to occur naturally.[4] It is decomposed by water or moisture from the air, and was synthesized only in 1973 by high temperature and very high pressures.[5]
