Physicochemical properties (density, dynamic viscosity, refraction index) of the DMSO-Cu(NO 3 ) 2 · 3H 2 O system are studied in the concentration range of 0.01–2 M at 298 K. The refraction index of a solution of copper(II) nitrate in dimethylsulfoxide (DMSO) is measured at 288–318 K. The excess and partial molar volumes of the solvent and dissolved substance are calculated analytically.
