The hydration of several iron(II) compounds has been studied by the Mössbauer technique and the X-ray diffraction method. The similarity of the Mössbauer parameters (isomer shift, quadrupole splitting) of aqueous iron(II) salt solutions suggested that Fe2+ contrary to Fe3+ in the above solutions is present mainly in the form of the hexaaquo complex. Based on the analysis of X-ray data, however, the existence of moderate Fe(H2O)5A complex formation in addition to the dominating hexaaquo complexes in chloride and sulfate solutions could not be excluded.
