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.
This dissolved carbon dioxide comes out of solution where the PCO2 is low, such as in the lungs. There it diffuses out of the capillaries into the alveoli to be exhaled.
