Web3) Maleic acid (C4H4O4) is a diprotic acid, which means it can donate two protons (H+) in aqueous solution. The given PKa1 and PKa2 values are the acid dissociation constants of the two ionizable hydrogens. The acid-base reaction for the first proton donation is as follows: C4H4O4 (aq) + H2O (l) ⇌ C4H3O4- (aq) + H3O+ (aq) Webcitraconic acid (C5H6O4, pKa1 = 2.29. pKa2 = 6.15), or maleic acid (C4H4O4, pKa1 = 1.92, pKa2 = 6.09).
