Calculate the ph of a buffer solution obtained by

Phosphoric acid is a triprotic acid (Ka1 = 6.9× 10-3, Ka2 = 6.2× 10-8, and Ka3 = 4.8× 10-13). To find the pH of a buffer composed of H2PO4-(aq) and HPO42-(aq), which pKa value would you use in the Henderson-Hasselbalch equation? Calculate the pH of a buffer solution obtained by dissolving 20.0 g of KH2PO4(s) and 30.0 g of Na2HPO4(s) in water and then diluting to 1.00 L.
