Key Differences

Carbonic Acid and Carbolic Acid are distinct chemical compounds with varying compositions and properties. While they both contain carbon, hydrogen, and oxygen, their structures and uses differ substantially.

Carbonic Acid is a weak acid formed when carbon dioxide (CO₂) dissolves in water. This reaction is reversible, and the equilibrium between CO₂ and Carbonic Acid plays a vital role in maintaining the pH of blood and in carbonated beverages. On the other hand, Carbolic Acid is an aromatic compound, better known as phenol, with a hydroxyl group attached to a benzene ring.
