Abstract
Refractive indices of the (Ag0.516, Tl0.484)NO3-H2O and (Ag0.516, Tl0.484)NO3-DMSO solutions have been measured at 90 °C over the whole composition range extending from the molecular solvents to the molten electrolyte. The molar refractivities of the melts were calculated from the refractive indices and a set of density values interpolated at the same temperature. Both systems were found to exhibit deviations from the ideal additive behaviour. The molar refractivities of the electrolyte (eutectic mixture AgNO3-TlNO3) and the solvent were calculated and their composition dependence and the deviations from the additivity are compared and discussed. The molar refractivity was found to be a complex, a less indicative, and a less sensitive indicator of the types and strength of ion-solvent interactions in these melts than the molar volume.
