The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula H C O 3 â and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.
The bicarbonate ion is HCO3-. Bicarbonate is an important buffer found in blood. Carbon dioxide is present in the blood in a number of forms such as bicarbonate, dissolved carbon dioxide and carbonic acid, of which 90% is bicarbonate or HCO3.CO2, in the form of bicarbonate, is directly involved in âlight reactions .â This âbicarbonate effectâ influences molecular processes.arbon dioxide is present in the blood in a number of forms such as bicarbonate, dissolved carbon dioxide and carbonic acid, of which 90% is bicarbonate or HCO3.
