History. Neglecting the $\ce{OH^-}$ produced by the autoprotolysis of water, it is valid to make the usual assumption that $\ce{[OH^-]}={[HCO_3^-]}$,and little of the carbonate goes to bicarbonate,so$\ce{[CO_3^{-2}]}={[CO_3^{-2}]_0}=0.5$ ,so thus Considering that CO3, or carbonic ACID, this substance would be Which conjugate acid/base appears?
