One of the buffers to maintain the pH of blood is the carbonic acid, H_2 CO_3, buffer. Carbonic acid is diprotic and it's equilibrium constants are K_a1 = 4.2 times 10^-7 and K_a2 = 4.8 times 10^-11. How would your prepare 5.0 L a carbonic acid buffer of a pH of 7.2 from 0.250 M H_2 CO_3? You have available NaHCO_3 (MW = 84.0) and Na_2 CO_3 (MW = 106).
