opper(II) carbonate (often called copper carbonateor cupric carbonate) is a blue-green compound (chemical formula CuCO3) forming part of the verdigris patina one sees on weathered brass, bronze, and copper. The colour can vary from bright blue to green, because there may be a mixture of both copper carbonate and basic copper carbonate in various stages of hydration. It was formerly much used as a pigment, and is still in use for artist's colours. It has also been used in some types of make-up, like lipstick, although it can also be toxic to humans. It also has been used for many years as an effective algaecide in farm ponds and in aquaculture operations. Copper carbonate was the first compound to be broken down into several separate elements (copper, carbon, and oxygen). It was broken down in 1794 by the French chemist Joseph Louis Proust (1754-1826).When burnt, it turns into a black powder. It can be used to bronze plate a metallic surface by adding suphuric acid and heat it then passing a charge through it with the meal in the liquid. Copper in moist air slowly acquires a dull green coating because its top layer has oxidised with the air. Some architechts use this material on rooftops for the interesting colour. The green material is a 1:1 mole mixture of Cu(OH)2 and CuCO3:[1] : 2Cu(s) + H2O(g) + CO2 + O2 → Cu(OH)2 + CuCO3(s) Copper carbonate decomposes at high temperatures, giving off carbon dioxide and leaving copper(II) oxide: : CuCO3(s) → CuO(s) + CO2(g) Basic copper(II) carbonate occurs naturally as malachite (CuCO3.Cu(OH)2) and azurite (Cu3(CO3)2(OH)2). # ^ Masterson, W.

What else can I help you with?
Compound for copper carbon and oxygen?
The compound you are referring to is copper carbonate, which has the chemical formula CuCO3. It is also known as copper(II) carbonate and is commonly found in nature as the mineral malachite.
Does carbonate produce copper oxide when heated?
Carbonate by itself is an ion that does not contain copper and therefore could not produce copper if heated. However, because carbonate is a negatively charged ion, no substantial number of carbonate ions can exist stably except in association with an equal number of positively charged cations to neutralize the electrical charge of the carbonate ions. If these cations are cations of copper, then copper oxide can be produced by heating the copper carbonate salt.
Copper sulfate and sodium carbonate physical or chemical change?
When copper sulfate and sodium carbonate are mixed together, a chemical reaction occurs. This reaction forms copper carbonate, a new substance with different properties than the reactants. Therefore, the mixing of copper sulfate and sodium carbonate is a chemical change.
Is copper carbonate a soluble solid?
Copper carbonate is not very soluble in water. When mixed with water, only a small amount of copper carbonate will dissolve, resulting in a cloudy blue solution.
How do you separate copper sulphate from calcium carbonate?
To separate copper sulfate from calcium carbonate, you can dissolve the mixture in water. Copper sulfate is soluble in water, while calcium carbonate is not. This solubility difference allows you to filter out the solid calcium carbonate and then evaporate the water to obtain copper sulfate crystals.
What two elements are copper carbonate made up of?
Copper carbonate is made up of the elements copper, carbon, and oxygen.
Which compounds make up copper carbonate?
Copper(II) Carbonate (or Cupric Carbonate) is made up of Copper ions, and Carbonate ions. The coppers have a +2 charge, and carbonate has a -2 charge. The formula is Cu(II)CO3
What is the name of this ternary salt cu2co3?
copper(II) carbonate or cupric carbonate
What is the word equation for the green precipitate of copper carbonate and sodium sulphate solution?
Copper(II) carbonate is insoluble in water and doesn't react with sodium sulfate. A green product, visible on ald objects made from copper or copper alloys, is a mixture of copper carbonate and copper hydroxide.
What compound will be formed between copper ion and carbonate ion?
Copper and carbonate ions form copper carbonate. In practice, copper carbonate usually contains hydroxide ions as well.
What is made when you mix sulphuric acid copper carbonate?
copper sulphate and carbon dioxide
Compound for copper carbon and oxygen?
The compound you are referring to is copper carbonate, which has the chemical formula CuCO3. It is also known as copper(II) carbonate and is commonly found in nature as the mineral malachite.
Is copper ii carbonate a compound or mixture?
It is a compound that is made up of carbon, copper and oxygen. The "ate" in carbonate stands for oxygen.
What compound is CuC03?
Copper Carbonate
What is copper carbonate plus potassium?
When copper carbonate reacts with potassium, it forms copper metal and potassium carbonate. This reaction is a redox reaction where copper is reduced and potassium is oxidized.
What kind of precipitate forms from copper chloride and sodium carbonate?
Copper carbonate would precipitate if you combined solutions of copper (II) chloride and sodium carbonate.
What is the precipitate of copper sulphate and sodium carbonate?
The precipitate formed when copper sulfate and sodium carbonate are mixed is copper carbonate. This reaction occurs because copper carbonate is insoluble in water and therefore forms a solid precipitate.
