Another buffer found in blood is based on the equilibrium between dihydrogen phosphate and monohydrogen phosphate. the reaction is:
H2PO4-(aq) + H2O(l) ---> H3O+(aq) + HPO4-2(aq)
If the pH of a blood sample was 7.10, what would you calculate as the ratio of [H2PO4-] to [HPO42-] ?
(Ka1= 7.5 * 10^-3 , Ka2= 6.2 * 10^-8 , Ka3= 3.6 * 10^-13)
