AI overview

Carbonic acid is a weak chemical compound formed when carbon dioxide dissolves in water, and it's the main ingredient that makes carbonated beverages fizzy. It matters because it plays an important role in Earth's carbon cycle and ocean chemistry, affecting everything from how shells form in the ocean to how the atmosphere interacts with water.

Encyclopedic overview

Carbonic acid is a chemical compound with the chemical formula H2CO3. The molecule rapidly converts to water and carbon dioxide in the presence of water. In contrast to early-twentieth century textbooks, numerous studies conducted since ca. 1990 identified H2CO3 as a real molecule with a distinct Raman spectrum and with a first-order life-time of ca. 20 ms at 37 °C. Solid anhydrous carbonic acid has also been isolated.

The interconversion of carbon dioxide and carbonic acid is related to the breathing process of all aerobic organisms and to the acidification of natural waters.
