Bicarbonate ion – Bicarbonate ion (HCO3
-) is a normal constituent of the blood. Bicarbonate is naturally produced by the reaction of carbon dioxide (CO2) with water (H2O) to produce carbonic acid (H2CO3), which dissociates to a bicarbonate ion and a proton (H+). Acid/base metabolism in the body is regulated by this chemical equation: |
CO2 + H2O <> H2CO3 <>H+ + HCO3-
