“…They are considered as potential environmentally friendly solvents to replace the common volatile organic solvents and thus reduce environmental footprints (Gomes et al, 2019 ; Kaur et al, 2020 ). In industrial applications, instead of pure compounds, frequently, mixtures of ILs with different solvents are used, and therefore, investigation of the behavior of binary or ternary mixtures of ILs is of great importance to unravel their structural characteristics which can provide valuable information regarding solute–solute and solute–solvent interactions (Zafarani-Moattar and Sarmad, 2012 ).…”

“…Kaur et al studied volumetric and acoustic properties of choline acetate IL in α, ω-alkane diols, at different temperatures (Kaur et al, 2020 ). Volumetric, acoustic, and spectroscopic properties of an aqueous ternary mixture of IL 1-hexyl-3-methylimidazolium bromide and amino acids ( l -alanine and l -phenylalanine) were investigated by Kumar and Sharma ( 2020 ).…”

The density, sound velocity, and viscosity of 1-ethyl-3-methylimidazolium chloride [C 2 mim]Cl in pure water and aqueous solutions of some electrolytes such as potassium chloride, potassium carbonate, and potassium phosphate (weight fraction of salt fixed at w s = 0. 11) have been measured over a wide range of temperatures from 298.15 to 318.15 K. The obtained experimental data have been used to compute various volumetric, compressibility, and viscometric parameters, e.g., apparent molar properties, limiting apparent molar and transfer properties. The co-sphere overlap model was employed to describe the dominant intermolecular interactions in the ternary solutions. Additionally, the structure making/breaking nature of the [C 2 mim]Cl in the ternary solutions has been discussed in terms of Hepler's constant and the temperature derivative of viscosity B -coefficient ( dB / dT ). The activation free energy of solvent and solute, activation enthalpy, and activation entropy have been calculated by the application of transition state theory. The calculated parameters have been interpreted in the sense of solvent–solute and solute–solute interactions. The Fourier transform infrared (FTIR) studies also have been done for the studied systems. Volumetric, acoustic, viscometric, and spectroscopic studies can render some evidence and help to understand the aqueous solution behavior of ionic liquids.
