Human blood contains one buffer system based on phosphate species and one based on carbonate species. Assuming that blood has a normal pH of 7.4 , what are the principal phosphate and carbonate species present? What is the ratio of the two phosphate species? (In the presence of the dissolved ions and other species in blood, Ka 1 of H3 PO4=1.3 ×10^-2, Ka 2=2.3 ×10^-7, and Ka 3=6 ×10^-12 ; Ka 1 of H2 CO3=8 ×10^-7 and Ka 2=1.6 ×10^-10.) | Numerade
