Phosphoric acid is a triprotic acid (Kal 6.9 × 10-³, K₁2 = 6.2 × 10−8, and K₁3 = 4.8 × 10-¹3). To find the pH of a buffer composed of H₂PO4 (aq) and HPO²(aq), which pKą value should be used in the a Henderson-Hasselbalch equation? pKal = 2.16 PK₁2 = 7.21 O PK₁3 = 12.32 a3 Calculate the pH of a buffer solution obtained by dissolving 19.0 g of KH₂PO4(s) and 29.0 g of Na₂HPO4(s) in water and then diluting to 1.00 L. pH =
