The best choice from Table 7.1 is lactic acid/lactate since it as a pK a of 3.85. However, note that phosphoric acid, with a pKa of 2.1, would actually be better. b) A concentration of hydronium (H3O +) ions of 5.2 x 10-8 M will generate a pH of 7.3 (pH = -log[H3O +]). The best choice from Table 7.1 is NaH 2PO4/Na2HPO4 since it as a pKa of 7.2.
