Ultrasonic density and velocity for dextrose have been calculated in 0.2 and 0.5 mol/kg aqueous NaCl and KCl solutions at 283.15, 288.15, 293.15 and 298.15 K for various molal concentrations from 0.001 to 0.1 molal. Thermodynamic parameters such as acoustic impedance (Z), adiabatic compressibility (β), relaxation strength (r), specific heat ratio(ϒ), change in an adiabatic compressibility (∆β), relative change in an adiabatic compressibility (∆β/β), non-linearity parameter (B/A), an isothermal compressibility (KT1), an internal pressure (Лi), molecular radius(Rm), an enthalpy (H), relative association (RA), intermolecular free length (Lf), surface tension (ϭ), and Lennard Jones potential (n) have been an obtained from literature formulae. To investigate the exact kind of molecular interaction NaCl and KCl interact with Dextrose at various concentrations and temperatures, an ultrasonic tactic was used. The result and discussion of all the parameters conclude that due to the higher changes present in KCl, the interaction is greater in the 0.5KCl solution among all systems.
