Phosphoric acid is a triprotic acid with the p K a values p K a 1 = 2.148 , p K a 2 = 7.198 , and p K a 3 = 12.375 . You wish to prepare 1.000 L of a 0.0300 M phosphate buffer at pH 7.520 . To do this, you choose to mix the two salt forms involved in the second ionization, NaH 2 PO 4 and Na 2 HPO 4 , in a 1.000 L volumetric flask and add water to the mark. What mass of each salt will you add to the mixture?
