Specification
Copper(II) oxide, with the CAS NO.1317-38-0, also known as cupric oxide, is a chemical compound. Its chemical formula is CuO. It has copper in its +2 oxidation state. It also has oxide ions. Copper(II) oxide is a black solid. It dissolves in acids to make copper(II) salts. It can react with carbon monoxide or hydrogen to make copper metal. It dissolves in very concentrated alkalis. It dissolves in ammonia to make a dark blue solution, similar to copper(II) hydroxide.
Preparation of Copper(II) oxide: It can be made by heating copper(II) hydroxide. It can also be made by heating copper in air. It can also be made by heating copper(II) carbonate or copper(II) nitrate.
Uses of Copper(II) oxide: Copper(II) oxide is used to color ceramics. It is also used to make thermite. It can react with many toxic chemicals to oxidize them, so they are not toxic any more. It can be added to vitamins to get copper into the body. It can also be added to clothing to kill germs.
