Coppersulfide, or coppersulphide, is an inorganic substance. Copper Sulfide Chemical Formula is: CuS. The cuprous ion is dark brown in color and is very polar. Insoluble. This is the second most insoluble substance (after silver sulfide). Its poor solubility causes some reactions that seem unacceptable.

About Copper sulfide cuS powder:

Copper Sulfide is inorganic compound, with chemical formula cuS. It is black and brown powder or granular material. The insoluble nature of this substance makes it one of most difficult to dissolve. The bonding of copper sulfide can’t be accurately described as simple oxidation forms, because the properties are covalent and not ionic. This results in a complex band structure.

Copper sulfide is a mineral and compound that can be divided in three categories: mixed single sulfide , single sulfide , and disulfide . Copper sulfide, also known as cuprizone, is a naturally occurring mineral. It conducts electrical currents moderately. Minerals and synthetic materials both contain copper sulfide.

Copper sulfide refers to a variety of compounds and minerals that are used in the production of synthetic and natural materials. Copper sulfide minerals are important economic ores. Copper sulfides include Cu2S (chalcocite) as well as CuS (copper porphyry). In the mining world, chalcopyrite or bornite, which is a copper-iron mixed sulfide compound, is often called “copper” sulfide. The composition of copper-sulfides is very variable, and can include many nonstoichiometric substances.

How does Copper sulfide cuS powder get produced?

The reaction between sulfur and copper is not able to be heated directly, and the result will be a mixture of cuprous sulfide.

2Cu+S==^==Cu2S , Cu+S==^==CuS

Copper powder and sulfur can be dissolved in carbon dioxide at 100 degrees to make pure copper-sulfide.

Cu+S==100 , CS2==CuS

Double decomposition is used to prepare copper sulfide in the laboratory.

CuCl2+H2S====CuS|+2HCl (weak acid to strong acid)

This reaction may occur when copper sulfide becomes too insoluble and causes the equilibrium balance to shift to the left.
