Copper(II) carbonate

Copper(II) carbonate, also known as cupric carbonate, is a chemical compound. Its chemical formula is CuCO3. It contains copper in its +2 oxidation state. It also contains carbonate ions.
Properties
Copper(II) carbonate is a blue-green solid. It is made when copper is in air for a long time and turns green. The other part of that coating is copper(II) hydroxide. It dissolves in acids to make carbon dioxide and a copper salt. It breaks down when heated to make carbon dioxide and copper(II) oxide.
Preparation
It can be made by leaving copper(II) hydroxide in air, which makes copper(II) carbonate. It can also be made by reacting copper sulfate and sodium carbonate. This makes sodium sulfate in solution.
Uses
Copper(II) carbonate can be used to kill algae. It is also used as a pigment.
Safety
It can irritate the skin. It is toxic since it dissolves in stomach acid to make copper ions in solution, which can be absorbed.
