Abstract

The stability constants, β1, of the monofluoride complex of Fe(III) have been determined in mixed methanol + water solvent system with 0.3 mol·dm−3 HClO4 using a solvent extraction technique. The values, in less than 0.31 mole fraction of CH3OH (X s) in the mixed CH3OH+H2O solvent solution, increase asX s increases. The variation of in β1 againstX s was analyzed to elucidate the variation of intraionic distance between Fe3+ and F−. The intraionic distance maintains constant inX s<0.05 and lengthens with an increase ofX s in 0.05<X s<0.31.
