When CO2 dissolves in water, part of the CO2 reacts with water forming carbonic acid, H2CO3, a diprotic acid with the following dissociation constants: Ka1= 4.3×10−7 , Ka2= 4.8×10−11. Consider an aqueous solution containing 0.45 M carbonic acid. Calculate the equilibrium concentration of CO32− ions in the solution. Calculate the equilibrium concentration of HCO3− ions in the solution. Calculate the equilibrium concentration of H3O+ ions in the solution.
