24. The pH of our blood is controlled by the bicarbonate buffer system:

CO2(g) CO2(aq) + H2O(l) H2CO3(aq) H+(aq) + HCO3-(aq)

Based only on the equilibria given here and the knowledge that CO2 is released into the blood in the tissues and removed from the blood in the lungs, predict which area of the body has a higher pH:

a) tissues
b) lungs
