We also applied both solution preparation methods to the preparation of Cd 2+ //F -//Na + //SO4 2-serial solutions. Like the solutions containing ZnF2, the 19 F NMR spectral difference (Fig. ) between both serial solutions containing CdF2 prepared by paths 1 and 2 is also observed when the CdF2 concentration is 0.01 mol•kg -1 . This suggests that the effect of solution preparation paths on the microstructure of solution containing F -and divalent cations is widespread.
