Ultrasonic velocity, density and viscosity have been measured for fructose in aqueous NaCl and MgCl2 at 298.15K, 303.15K & 308.15K. Thermodynamic parameters such as adiabatic compressibility(β), acoustic impedance (z),intermolecular free length(Lf) and relative association number (RA) have been obtained from the experimental data for the solutions of inorganic salts i.e. NaCl and MgCl2 with fructose at various concentrations and temperatures, with a view to investigate the exact nature of the molecular interactions. Adiabatic compressibility and intermolecular free length decreases with increase in concentration and temperature and gradually increases with concentration of solutes. These parameters have further been used to interpret the hydrophilic part of the solute and molecular interactions in the solutions.
