“…The increase in V ϕ 0 values from H 2 O to binary aqueous [Emim][EtSO 4 ] samples can therefore be attributed to a decrease in shrinkage volume, providing positive transfer volumes. This could be explained by the cosphere overlap model – proposed by Friedman and Krishnan, which states that when two ionic species (ion–hydrophilic and hydrophilic–hydrophilic groups) are overlapped, their volume is enhanced, whereas when two non-ionic species (hydrophobic–hydrophobic groups and ion–hydrophobic groups) are overlapped, their volume is decreased. In the present work, positive transfer volumes are observed due to the hydrophilic–hydrophilic and ion-hydrophilic groups’ interactions that are dominating over the ion–hydrophobic and hydrophobic–hydrophobic interactions.…”

The present research work is concerned with the thermophysical properties of tripotassium citrate and sodium benzoate in aqueous (0.10, 0.15, and 0.20) mol·kg–1 1-ethyl-3-methylimidazolium ethyl sulfate solutions at temperatures ranging (293.15–313.15) K and 101.3 kPa pressure. The experimentally acquired density, sound speed, and viscosity data have been employed to determine numerous densimetric, acoustic, and viscometric parameters including the apparent molar volumes (V ϕ), partial molar volumes at infinite dilution (V ϕ 0), limiting apparent molar expansibilities (E ϕ 0), apparent molar isentropic compressibilities (K ϕ,s), transfer properties, hydration number (n H), viscosity B-coefficients, and thermodynamic parameters of viscous flow (Δμ1 0, Δμ2 0, ΔH 2 0, and TΔS 2 0). The above-mentioned parameters have been evaluated for the examination of interactions that are prevailing among tripotassium citrate/sodium benzoate and 1-ethyl-3-methylimidazolium ethyl sulfate in an aqueous medium. In addition, UV spectral analysis was used for the examination of interactions existing among the considered systems. Furthermore, the band gaps between the highest occupied molecular orbital and the lowest unoccupied molecular orbital for the studied systems and the interaction characteristics have been calculated using density functional theory. The obtained results inferred the predominance of the hydrophilic–hydrophilic interactions in the systems under investigation.

Understanding the molecular dynamics and intermolecular interaction of liquid mixtures can be greatly aided by ultrasonic study. Sound speed and Density of glycols ethers (phenoxyethanol and butoxyethanol) in solutions of a well-known sugar alcohol (d-Mannitol), were measured using the AntonPaar (DSA 5000 M) at concentrations of (0.02, 0.06, and 0.10) mol.kg−1 and fixed experimental pressures (0.1 MPa) over the entire temperature range (288.15, 293.15, 298.15, 303.15) K. With the experimental data of velocity and density, a number of additional dependent basic acoustic-thermodynamic parameters, namely Vander Waal’s constant (b), intermolecular free length (Lf), acoustic impedance (Z), adiabatic compressibility (β), Rao’s constant (R), and Wada’s constant (W) have been evaluated. Through these parameters, interactions between solutes and their solvents are expressed in terms of solute-solvent interactions. Research is also done on the solute’s capacity to create or destroy structures in a solvent. The inter-molecular interactions amidst the ternary mixture of glycols ethers and d-mannitol in aqueous medium were analyzed.
