ABSTRACT
Partial molar volumes ( ) and viscosity B-coefficients of sodium molybdate in 1,3-dioxolane + water mixtures have been determined from solution density and viscosity measurements at 303.15, 313.15, and 323.15 K and at various electrolyte concentrations. Also, the adiabatic compressibility of different solutions has been determined from the measurement of sound speeds at 303.15 K. The experimental density data were evaluated by the Masson equation, and the derived parameters were interpreted in terms of ion-solvent and ion-ion interactions. The viscosity data have been analyzed using the Jones-Dole equation, and the derived parameters, B and A, have also been interpreted in terms of ion-solvent and ion-ion interactions, respectively. The structure making or breaking capacity of the electrolyte under investigation has been discussed in terms of the sign of . The compressibility data obtained from sound speeds of different solutions indicate the electrostriction of the solvent molecules around the ions.
