Pyrophosphate - Wikipedia

Pyrophosphoric acid is a tetraprotic acid, with four distinct pKa's: H4P2O7 ⇌ [H3P2O7] + H , pKa = 0.85 [H3P2O7] ⇌ [H2P2O7] + H , pKa = 1.96 [H2P2O7] ⇌ [HP2O7] + H , pKa = 6.60 [HP2O7] ⇌ [P2O7] + H , pKa = 9.41 The pKa's occur in two distinct ranges because deprotonations occur on separate phosphate groups. For comparison with the pKa's for phosphoric acid are 2.14, 7.20, and 12.37.
