Abstract
The dissociation constants of salicylhydroxamic acid (H2L), pKa1 = 6.73 and pKa2 = 9.15 (20 °C, I = 1.0 (NaClO4)), and the stability constant of the FeHL2+ complex, logβ = 9.09, were determined by the potentiometric and spectrophotometric methods. The low-soluble Fe(OH)(HL)2.3 H2O complex was also isolated. The reagent can be conveniently used as an indicator for the chelometric determination of iron.Keywords
