AI overview
A carbonate is a type of salt that contains a carbonate ion (CO₃²⁻), and the term can also refer to organic compounds with a similar chemical structure. Carbonates are important because they appear widely in nature—in rocks, minerals, and shells—and have many practical uses in industry and everyday products.

A carbonate is a salt of carbonic acid, (), characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO32–. The word "carbonate" may also refer to a carbonate ester, an organic compound containing the carbonate group .
The term is also used as a verb, to describe carbonation: the process of raising the concentrations of carbonate and bicarbonate ions in water to produce carbonated water and other carbonated beverageseither by the addition of carbon dioxide gas under pressure or by dissolving carbonate or bicarbonate salts into the water.
