In the carbonate system the, bicarbonate ions, [HCO 3 −] and the, carbonate ions, [CO 3 2−] have become converted to carbonic acid [H 2 CO 3] at this pH. This pH is also called the CO 2 equivalence point where the major component in water is dissolved CO 2 which is converted to H 2 CO 3 in an aqueous solution.
