Solubilities of iron(III) complexes of 3-hydroxy-2-ethyl-4-pyranone and of 3-hydroxy-1,2-dimethyl-4-pyridinone in aqueous salt solutions

Solubilities are reported for the tris-ligand–iron(III) complexes of 3-hydroxy-2-ethyl-4-pyranone and of 3-hydroxy-1,2-dimethyl-4-pyridinone in aqueous solutions of alkali halides and of ammonium and tetraalkylammonium bromides. The Setchenow coefficients estimated from salt effects on solubilities for these complexes are compared with those for other inorganic complexes.
