Phosphoric acid is a triprotic acid with the p?a values p?a1=2.148, p?a2=7.198, and p?a3=12.375. You wish to prepare 1.000 L of a 0.0300 M phosphate buffer at pH 7.580. To do this, you choose to mix the two salt forms involved in the second ionization, NaH2PO4 and Na2HPO4, in a 1.000 L volumetric flask and add water to the mark. What mass of each salt will you add to the mixture?
mass NaH2PO4= g
mass Na2HPO4= g
What other combination of phosphoric acid and its salts could be mixed to prepare this buffer?
Select all that apply.
Na2HPO4 and Na3PO4
NaH2PO4 and Na3PO4
H3PO4 and Na3PO4
H3PO4 and Na2HPO4
H3PO4 and NaH2PO4
