WebSep 13, 2024 · Phosphoric acid (H3PO4) is tribasic, with pKa's of 2.14, 6.86, and 12.4. The pKa value is method to indicate the acid strength. It is the negative log of the acid dissociation constant or Ka value. A lower pKa value indicates a stronger acid. Hence the lower value indicates the acid more fully dissociates in water. WebPhosphoric acid is a triprotic acid which undergoes a stepwise dissociation as follows, where K 1 = 6.5 x 10 -3 ; K 2 = 6.2 x 10 -8 ; and K 3 = 3.6 x 10 -13 .
