Carbonate
CO₃²⁻
Carbonate is a compound composed of carbon and oxygen, typically in the form of a polyatomic ion with the chemical formula CO32-. Carbonate ion is a versatile anion that occurs in many minerals, including limestone, dolomite, and marble. These minerals play an important role in the formation of sedimentary rocks and can also be used as a source of calcium, magnesium, and other essential elements.
Carbonates are also important in environmental chemistry, as they help regulate the pH of natural waters and can act as buffers against acid rain. For example, calcium carbonate can neutralize acidic pollutants in water bodies and soils, helping to maintain a healthy ecosystem.
In addition to its natural occurrence, carbonate is used in a wide range of industrial applications. For example, sodium carbonate (also known as soda ash) is used in the production of glass, detergents, and other chemicals, while calcium carbonate is used as a filler in plastics, paper, and rubber products.
Overall, carbonate is an important compound with a wide range of uses in both natural and industrial settings.
