At seawater, pH (8.2), the distribution of the three species, CO 2 (aq), HCO 3 – (aq), and CO 3 2– (aq) is 0.5%, 89%, and 10.5%. This can be rationalized as follows, the first equilibrium is dominated by the concentration of bicarbonate in the solution, with very little CO 2 (aq) left unreacted in solution. In contrast the second equilibrium favours the reactant side, and as such …
