Abstract

The complexes formed by salicyluric acid and several substituted derivatives of salicylic acid with ferric ions have been investigated at 25°and in a medium of ionic strength 0·1 using pH and oxidation-potential measurements. The equilibrium constants of complex formation of the 1: 1 and 1: 2 mole ratio iron (III)-acid complexes formed are discussed with reference to the inductive, mesomeric, and steric effects of substituents. Appoximate values of the constants for the 1: 3 complexes of some of the acids were also obtained, and evidence indicating the possible presence of a protonated 1: 1 complex is reported.
