Copper(I)

Copper(I) also known as cuprous, is an oxidation state of copper where it has lost one electron. It is represented by the chemical symbol Cu+.

Chemical Properties

Copper(I) is less stable than copper(II), and will oxidize to copper(II) in the presence of air. It forms a variety of compounds, including copper(I) chloride (CuCl), copper(I) oxide (Cu2O), and copper(I) sulfide (Cu2S).

Physical Properties

Copper(I) compounds are typically white or colorless in their anhydrous forms, and blue or green when hydrated. They are less stable than their copper(II) counterparts, and are therefore less commonly encountered in everyday life.

Uses

Copper(I) compounds are used in a variety of applications, including as catalysts in the chemical industry, in the production of semiconductors, and in the glass industry.

Health Effects

Exposure to copper(I) compounds can cause a variety of health effects, including irritation of the eyes, skin, and respiratory tract. Ingestion can cause nausea, vomiting, and diarrhea. Long-term exposure can lead to liver and kidney damage.
