In this paper, the ionic liquid [empy][EtSO4] Was synthesized, and its experimental densities, dynamic viscosities, and refractive indices were determined from (298.15 to 343.15) K. Densities and dynamic viscosities for [empy][EtSO4] + ethanol and + water at temperatures T = (298.15, 313.15, and 328.15) K have been measured over the whole composition range and at 0.1 MPa. The determined physical properties have never been reported. Excess molar volumes and viscosity deviations for the binary systems at the above-mentioned temperatures were calculated and fitted to the Redlich-Kister equation. Refractive indices were measured at 298.15 K over the whole composition range for ethanol (1) + [empy][EtSO4] (2) and water (1) + [empy][EtSO4] (2) binary systems. The results were used to calculate deviations in the refractive index.
