+ Composition of Inorganic Conjugate Acid-Base Pairs in Blood The following table gives the acid-dissociation constant values, Ka, for carbonic acid, H2CO3, and phosphoric acid, H3PO4. Acid Ka1 Ka2 Ka3 H2CO3 4.3x10-7 5.6x10-11 not applicable H3PO4 7.2x10-3 6.2x10-8 4.2x10-13 pH of blood The two most important inorganic blood buffers (acid-base conjugate pairs) are the phosphoric acid and carbonic acid systems. The pH of normal blood is 7.40. Part A At a pH of 7.40, what is the ratio of the molar concentrations of PO43- to HPO42-? Express your answer using two significant figures.
