“…The results of Table S3 make it abundantly evident that the inferred data is positive. The caging effect, or the increase in the volume of the solute molecules’ solvation shells upon changing the concentration of the solvent media, is the cause of the positive E ϕ 0 values, which denote the persistence of improved interactions between the solute molecules and solvent molecules. – …”

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.

“…The positive values of E ∞ indicate strong solute (amino acid salt)-solvent(water) interactions in all investigated amino acids salt solutions. The Hepler's constant 16) is helpful to understand the structure making/breaking behavior of the solute which is calculated by the following expression (5).…”

Objectives:To produce new and accurate data of density of aqueous solution of amino acid salts at different temperatures and to correlate it with molality. Methods: The densities of aqueous solutions of sodium salts of Amino acids such as L-cysteine, L-leucine, L-proline and L-valine have been measured using double-arm Pycnometer, placed in a transparent glass-walled water bath having thermal stability of (0.01 K) at concentrations range (0.01 to 0.15) mol L -1 and at 298.15, 303.15, 308.15, and 313.15 K. From density data ahead, apparent molar volumes (V ϕ ), the partial molar volumes (V ϕ 0 ), expansion coefficient (E ∞ ) and Hepler's constantwere calculated and analysed on the basis of the intermolecular interaction and molecular structure. Findings: The densities are observed to increase with concentration and decrease with increasing temperature. The positive values of partial molar volume (V ϕ 0 ) indicate strong sodium amino acids -water interactions. Novelty:For studied aqueous sodium salt solution of Amino acids, such properties have not yet been reported in the open literature and at such a lower concentrations range (0.01 to 0.15) mol L -1 .
