Development of a Modified Bromley's Methodology for the estimation of ionic media effects on solution equilibria Part 4. The chemical model of Fe(III) with the halide ligands in aqueous solution at 25 degrees C

Belaustegi Y, Olazabal MA, Madariaga JM

The Modified Bromley's Methodology (MBM) has been used to construct the basic chemical model between Fe(III) and OH- and the halide ligands Cl-, Br- and F- in NaClO4 medium at 25 degrees C, obtaining the thermodynamic constants and the corresponding interaction parameters for each equilibrium. This basic model has been extended to KNO3, HCl, and KCl media obtaining the corresponding interaction parameters. The applicability of the model is also discussed.
