The excess molar volumes, viscosity deviations and changes in isentropic compressibility for the binary mixtures have been calculated and discussed in terms of hydrogen bonding and structure-breaking effect. The computed results are fitted to the Redlich-Kister polynomial. The results clearly indicate that there is a strong association in the mixtures studied. © 2010 Elsevier B.V.Aqueous ethanolExcess molar volumesGlycyl-glycineHydrogen bondingsIsentropic compressibilityNiCl2Redlich-Kister polynomialsTemperature rangeViscosity deviationViscosity deviationsCompressibilityEthanolHydrogen bondsViscosityVolume measurementBinary mixtures
