Acetic acid, also known as ethanoic acid and methanecarboxylic acid, is a colorless liquid that has a strong and distinct pungent and sour smell. Its chemical formula is C2H4O2: it has two carbon (C) atoms, four hydrogen (H) atoms and two oxygen (O) atoms.t is an organic compound that is classified as a carboxylic acid because a carboxyl (-COOH) group is present in its chemical structure. Acetic acid is also known as the second simplest carboxylic acid.
Carbonic acid is also an archaic name for carbon dioxide. Carbonic acid is a chemical compound with the chemical formula H 2 CO 3 (equivalently OC(OH) 2). It is also a name sometimes given to solutions of carbon dioxide in water (carbonated water), because such solutions contain small amounts of H 2 CO 3.n physiology, carbonic acid is described as volatile acid or respiratory acid, because it is the only acid excreted as a gas by the lungs. Carbonic acid, which is a weak acid, forms two kinds of salts, the carbonates and the bicarbonates.
