Studies were conducted to analyze the intermolecular interactions between dextran solute and 1M sodium hydroxide solvent in aqueous solutions at different temperatures and concentrations. This involved measuring ultrasonic speed (U), density (ρ), and viscosity (η). Various acoustic parameters such as free volume (Vf), internal pressure (Пi), Rao’s constant (R), and Wada's constant (W) were calculated at a constant frequency using the experimentally obtained values of density (ρ), viscosity (η), and ultrasonic speed (U) of the solutions. The results provide insight into the temperature and concentration dependence of these parameters and the intermolecular interactions within the system. This investigation offers valuable information about the interaction type between solute and solvent, structural rearrangement, and the extent of molecular interaction in liquid solutions.
