Employing these, several excess properties viz., excess molar volume,V_m^E, excess speed of sound, uE, excess isentropic compressibility, κ_s^E, excess molar isentropic compressibility, K_(s,m)^E, and excess isobaric thermal expansion,α_p^E, of the binary systems were calculated. To better understand the solute and solvent interactions, excess partial molar volumes, and , and excess partial molar volumes, and of the components at infinite dilution also measured. The excess parameters were subjected to fitting using the Redlich-Kister polynomial equation. The findings were analysed to investigate the prevalent molecular interactions and their consequence on the structural aspects.
