	Copper(II) carbonate - Wikipedia, the free encyclopedia
		Copper(II) carbonate (often called copper carbonate or cupric carbonate) is a blue-green compound (chemical formula CuCO
		The color 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.

	Copper carbonate (UK PID)
		Copper carbonate hydroxide is formed by the action of air and water on elemental copper.
		Although copper carbonate hydroxide is practically insoluble in water its solubility in dilute acid may facilitate gastrointestinal absorption.
		The authors suggested the staining was attributed to copper adherence from the brass fume and its subsequent conversion to copper carbonate.

	Copper(II) oxide - Wikipedia, the free encyclopedia
		Copper(II) oxide or cupric oxide (CuO) is the higher oxide of copper.
		It is a fl solid with an ionic structure which melts above 1200 °C with some loss of oxygen.
		→ CuO + CO Copper(II) oxide is a basic oxide, so it dissolves in mineral acids such as hydrochloric acid, Sulfuric acid or nitric acid to give the corresponding copper(II) salts:

	Copper and copper salts (PIM G002)
		The acetate, chloride, nitrate and sulphate salts are soluble in water, whereas the oxide, carbonate and cyanide salts are insoluble (Weast, 1976-77).
		Copper(II) salts are readily reduced and therefore should be considered reactive with reducing agents, strong acids, alkali metals and finely powdered metals.
		Copper(I) compounds are incompatible with oxidising agents and alkali metals and in some cases air, light and moisture.

		And second, using a metal displacement reaction, you are required to prepare crystals of a second ethanoate or chloride.
		One starting material should be some of your freshly prepared copper(II) ethanoate or copper(II) chloride; and the other should be a suitably correct choice from: cobalt; cobalt(II) carbonate; manganese; manganese(III) carbonate; silver; silver(I) carbonate; zinc; and zinc carbonate.

		The growth of calcite crystals involves the adsorption of calcium and carbonate ions to the crystal surface.
		The carbonate ions are found to form bidentate complexes in the equatorial plane; the larger coupling constants reflect the delocalization of spin density from the Cu(II) ion over the s and p bonds to the 13C nuclei.
		The speciation of the carbonate surface depends on pH and solution composition and the Cu(II) ions are expected to form different complexes, depending on the available carbonate surface ligands (Van Cappellen et al., 1993).

		When alloyed with 1% carbon iron forms mild steel which is not brittle, but is more malleable and corrosion resistant than cast iron.
		Copper is used for cooking pans because it is relatively unreactive to water and therefore doesn't corrode easily, readily beaten or pressed into shape but strong enough, it is high melting and a good conductor of heat.
		Copper is also used as a roof covering and weathers to a green colour as a surface coating of a basic carbonate is formed on corrosion.
