Carbonic acid: Carbonic acid Other names Carbon

Carbonic acid Carbonic acid Other names Carbon dioxide solution Identifiers CAS number 463-79-6 SMILES C (=O) (O)O Properties Molecular formula H2CO3 Molar mass Carbonic acid (ancient name acid of air or aerial acid) is a weak acid with the formula H 2 CO 3. It is formed in small amounts when carbon dioxide is dissolved in water, and it is usually found only in solution. Carbonic acid is a weak acid formed by dissolving carbon dioxide in water. It is involved in many natural processes, such as soda fizz, blood pH regulation, and rain acidity. Carbonic acid, a compound of the elements hydrogen, carbon, and oxygen. It is formed in small amounts when its anhydride, carbon dioxide, dissolves in water. It plays a role in the formation of cave structures and the transport of carbon dioxide in the blood.
