Density , ultrasonic velocity and surface tension were measured for maltose solution in aqueous medium and non aqueous medium having the higher concentration 0.1-0.9 M at 318.15 k. From the experimental data adiabatic compressibility(β,), free length, acoustic impedance, were calculated. .From the data it is observed that the density and ultrasonic velocity acoustic impedence and relative association increases with increase the concentration of solute while adiabatic compressibility and free length deceases. Surface tension increased with increased concentration indicating that existence of large attractive intermolecular forces .The intermolecular interactions have been observed , which suggest the solute-solvent interaction.
