In aqueous solution phosphoric acid behaves as a triprotic acid. H3PO4 ⇌ H2PO−4 + H , pKa1 = 2.14 H2PO−4 ⇌ HPO2−4 + H , pKa2 = 7.20 HPO2−4 ⇌ PO3−4 + H , pKa3 = 12.37 The difference between successive pKa values is sufficiently large so that salts of either monohydrogen phosphate, HPO2−4 or dihydrogen phosphate, H2PO−4, can be prepared from a … WebApr 28, 2024 · the simplified formula p H = ( p K a 1 + p K a 2) / 2 is right enough. If p K a 1 = [ H A X −], the p H correction is cca + 0.15 = log ( 2) / 2 And then we can use this equation to iterative corrections, with [ M H A] being concentration of the used acidic salt. The fraction is the classical formula to calculate ion fraction.

WebIt is a relatively strong, dissociated acid, enabling it to easily acidify colas to the low desired pH (2.5) needed to establish proper carbonation, although its antimicrobial efficacy is far inferior to most organic acids, principally due to its dissociated state, which precludes ease of transport across the bacterial membrane.
