Copper(II) oxide or cupric oxide is an inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu2O or copper(I) oxide (cuprous oxide). As a mineral, it is known as tenorite. It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds.
Copper (I) Oxide has the chemical formula Cu2O and is known as Cuprous Oxide. It is covalent and can be reduced by Hydrogen by applying heat. It is subjected to acid solution for disproportionation and produces Copper (II) Oxide. To get vice versa, the Copper (II) Oxide can react with metallic Copper in the presence of heat to produce Copper (I) Oxide. Cuprous Oxide appears in red in solid form. The reaction with the air creates a thin oxide layer that acts as a barrier against corrosion.
The compound Copper (II) Oxide with the chemical formula CuO is also called Cupric Oxide. It is an inorganic compound used as a precursor in many copper products. It is found naturally on the Earth. For synthetic preparation, Copper metal is heated in the air to get Cupric Oxide. It is mixed as a component in many over-the-counter supplements for vitamins and minerals for human consumption.
1. It is actively used as a component of the pigments used to color various products, including enamels, artificial gems, and ceramics.
2. It is also used in manufacturing insecticides and fumigants.
3. Copper (II) Oxide is used as an anti-fouling agent for painting the boat hulls.
4. Wood industry is also one of the popular application areas where Cupric Oxide is used in wood preservatives.
5. Cupric Oxide is used as a firework's propellant.
Copper(II) oxide or cupric oxide (formula CuO) is a high oxide of copper. It is a black material that often coats old pieces of copper, most commonly found in pure form as a powder.
Copper(II) oxide is a black colored, ionic oxide. It is formed by oxidation of copper metal either with a chemical oxidizer, by heating in atmospheric oxygen or by electrochemical oxidation using copper as a anode. cupric oxide can be converted back to copper metal by carbothermal reduction, in which it is reduced by carbon under strong heat.
Most acids will dissolve copper(II) oxide to give their corresponding copper(II) salts.
Copper(II) oxide is most commonly used for coloring materials such as cloth and ceramic due to its deep black color. Therefore, it can be bought from pottery supply stores.
Copper salts can be precipitated with either a carbonate or hydroxide to form either copper(II) carbonate or copper(II) hydroxide. These salts can be heated to from copper(II) oxide.
Copper oxide can also be produced from electrolysis using a copper anode and a dilute solution of hydroxide dissolved in water. This product should be heated at over 200°C to decompose hydroxide impurities.[1]
