Abstract: The densities, conductivities, and viscosities were measured for ternary solutions of N-hexyl, methylpyrrolidinium bromide ([PP1,6]Br)-N-butyl,methylpyrrolidinium bromide ([PP1,4]Br)-H2O and its binary subsystems [PP1,6]Br-H2O and [PP1,4]Br-H2O at (298.15, 303.15, 308.15, and 313.15) K, respectively. The results were used to test the predictability of the simple equations established for the prediction of density, conductivity, and viscosity of the mixed electrolyte solutions. The results show that the examined simple equations can offer good predictions for density, conductivity, and viscosity of the mixed ionic liquid solutions in terms of the corresponding properties of its binary subsystems of equal ionic strength.

Key words: Density, Conductivity, Viscosity, Prediction, Ionic liquids
