In solution chemistry, the way for proper understanding of the different phenomena regarding the molecular interactions on the basis of quantitative influence of the solvents and the extent of interactions of ions in solvents. Here in this study, the acoustical properties have been investigated from the ultrasonic velocity and density measurements of substituted heterocyclic drug (Spectinomycin hydrochloride) in Methanol+water , Acetonitrile +water and 1, 4-Dioxane + water at 298.15o. The measurements have been performed to evaluate acoustical parameters such as Density, viscosity and ultrasonic velocity , Excess viscosities and excess molar volume ,Excess molar free energy , Coefficient of viscosity (ηr), Apparent molar volume ( ) & Solvation number (Sn), Ultrasonic velocity , Apparent molar compressibility , Relative association , Adiabatic compressibility , Intermolecular free length Specific acoustic impedance .
