Basic Copper(II) Carbonate

Basic Copper(II) Carbonate is an inorganic chemical compound with the chemical formula Cu2(OH)2CO3 and with a second more precise name of copper carbonate dihydroxide. it is known as basic copper carbonate because neutral copper(II) carbonate is unstable and readily reacts with water in the air to form basic copper(II) carbonate.

Synthesis
Basic copper(II) carbonate is normally synthesised by reacting an aqueous solution of copper(II) sulfate with sodium carbonate.

It can also be prepared in the same way, substituting sodium carbonate with sodium bicarbonate.

Reactions
Basic copper(II) carbonate is a precursor to many other copper salts as reacting it with an acid creates the respective copper salt under most conditions. Some exceptions include weak organic acids such as citric acid. At higher temperatures, around 200°C it decomposes to copper(II) oxide with the release of carbon dioxide and water.
