Abstract
The carbonyl group of compounds of the phenacyl- and benzoylethyl-pyridinium type is recognized as a potential σ donor ligand which can produce complexes with the aquapentacyanoferrate(II) ion. Its reactive form is the ionized one i.e. the enolate ion. A detailed spectrophotometric investigation has been made for the reaction of the aquapentacyanoferrate(II) ion with 1-benzoylethylpyridinium chloride. The equilibrium constant of the produced complex was derived using two literatury available additional types of processing the molar ratio method’s experimental data which were not found to be applied to this type of complexes. The kinetics of this substitution reaction were studied in buffered solutions at pH = 8.0 and I = 0.05 M. The obtained results are consistent with a dissociative mechanism.
