Short Answer
To simulate the pH of blood, which is 7.4, an undergraduate researcher in a biology lab produced a buffer solution by dissolving sodium dihydrogen phosphate (Ka 6.2 108) and disodium hydrogen phosphate (Ka 3.6 1013) together in an aqueous solution. What mole ratio of Na2HPO4/NaH2PO4 did she need to use?
