摘要：

Density, viscosity and ultrasonic velocity have been measured for mixtures of aqueous choline chloride with three different electrolytes (ZnSO4, NaCl & KCl) under atmospheric pressure at various concentrations and 298.15 K. Refractive index measurements have been carried out at five different temperatures ranging from 308.15 to 328.15 K with 5 K difference. Thermodynamic and thermophysical parameters like isentropic compressibility (βs),acoustic impedance (Z), intermolecular free length (Lf), relative association (RA), viscous relaxation time (τ), Gibbs free energy (ΔG), surface tension, free volume (Vf) and internal pressure (Pi) has also been evaluated. The viscosity measurements were correlated with the Jones Dole coefficients and the interactions have been explained on the basis of Kosmotropic and Chaotropic behavior. The findings have been utilized to understand the presence of solute – solvent interactions and the structural effects on the solvent in solutions to analyze the molecular interactions prevalent in the systems. © 2020 Elsevier B.V.
