The thermodynamic behavior of L-serine and Lthreonine in water and in an ionic liquid, 1-butyl-3-methylimidazolium bromide, containing water is examined using experimental data from acoustic, volumetric, and viscometric studies at T = (293.15 to 313.15) K and an experimental pressure of 101.3 kPa. The limiting apparent molar volume, V 0 ϕ , and limiting apparent molar isentropic compressibility, K 0 ϕ , s , are calculated from apparent molar parameters (volume, V ϕ , and isentropic compressibility, K ϕ , s ), respectively. The empirical parameters, S v and S k , are also computed. The experimental and computed data are utilized to evaluate the transfer properties (Δ tr V 0 ϕ and Δ tr K 0 ϕ , s ) of the chosen amino acids from water to the aqueous solutions of ionic liquid. The transfer property for these amino acids is positive at all concentrations of ionic liquids and all temperatures. This has been explained based on the cosphere overlap model. The viscosity B coefficients are evaluated from viscosity using the Jones−Dole equation. In ternary solutions (L-serine/L-threonine + water + ionic liquid), the thermodynamic properties are utilized to understand the mixing effects in aqueous solutions and to gather essential information about proximities and intermolecular interactions. The density functional theory is also used to validate the experimental results. The absorption spectra of amino acids in water as well as ionic liquids containing water are recorded to affirm the interactions prevailing in the system.

“…The S k * parameter is indicative of solute–solute interactions in the mixtures, which are very small compared to the values of K ϕ,S 0 . These diminished values of S k * suggest that the contribution of solute–solute interactions in the system is completely insignificant and that solute–solvent interactions are prominent in the liquid system. − …”

Measurement of the Density and Ultrasonic Speed of the Sound of Poly(ethylene glycols) (600 and 6000) in Aqueous Vitamin B₅ Solutions at Different Temperatures

The present study involves measurement of the density and ultrasonic speed of sound via Anton Paar DSA 5000 M for the binary mixture of water + poly(ethylene glycol) 600/poly(ethylene glycol) 6000 and ternary mixture of water + d-Panthenol + poly(ethylene glycol) 600/poly(ethylene glycol) 6000 covering a whole range of compositions (0.00, 0.02, 0.07, and 0.12 mol kg–1) at 0.01 MPa pressure from 288.15 to 318.15 K. The volumetric properties (apparent molar volume, partial molar volume, and partial molar volume of transfer) are evaluated from the density data; meanwhile, the speed of sound data is utilized to determine the acoustic properties (apparent molar isentropic compression, partial molar isentropic compression, and partial molar isentropic compression of transfer). This investigation is further extended by calculating the partial molar expansibility with its first derivative and pair-triplet interaction coefficients from these derived thermodynamic parameters. The obtained results from these calculated parameters are expressed as solute–solvent, ion–hydrophilic, hydrophilic–hydrophilic, and dipole–dipole interactions prevailing in the liquid sample.

“…Consequently, these criteria cannot be taken as markers of structure-making/breaking trends despite their widespread use in the literature. Notably, despite the lack of an explicit link to any actual microstructural feature of the solutions under study, the structure-making/breaking criterion around the sign of (∂ B /∂ T ) P has been regularly used in combination with, or as a complement to, the isobaric expansivity-based criterion for the structure-making/breaking ability of infinitely dilute solutes, as attested by a representative sample of the relevant literature. − …”

We analyzed the consistency, or lack thereof, of the conjectured connection between the sign of Jones−Dole's Bcoefficient, or its isobaric-temperature derivative, and the structure-making/breaking ability of a solute in a dilute solution. We sought to shed light on some crucial issues, including (i) whether Jones−Dole's B-coefficient contains any embedded microstructural information, (ii) whether we can either assign any definite foundation to the widely used assumption about the sign of the Bcoefficient and its structure-making/breaking trend or provide a rational justification for its use as a structure-making/breaking marker, and (iii) whether we actually need Jones−Dole's B-coefficient and its isobaric-temperature derivative as markers for the interpretation of structure-making/breaking trends. Thus, we first addressed the fundamental (statistical mechanical) microscopic to (thermodynamic) macroscopic foundations of a rigorous approach to the structure-making/breaking ability of a solute, regardless of the type of solvent or nature of the solute−solvent intermolecular interaction asymmetries, and its exact relationships to the resulting solution thermodynamics. Then, we derived the required conditions for the signs of the B-coefficient and/or its isobaric-temperature derivative to describe either a structure-making or a structure-breaking event, according to the actual solute-induced perturbation of the solvent microstructure, and consequently, tested the rationale underlying the B-based conjectured structure-making/breaking markers. Moreover, we invoked a well-known transition-state (TS) interpretation of the B-coefficient to connect it explicitly to the derived molecular-based structure-making/breaking signature and to find under which TS conditions the signs of the B-coefficient and its temperature derivative could describe the actual solute-induced perturbation of the solvent microstructure. We illustrated the actual structure-making/breaking behavior for a series of aqueous solutes over a wide range of solute−solvent intermolecular interaction asymmetries and compared their behavior against that predicted by Jones−Dole's based markers. This comparison, supported by rigorous thermodynamic arguments, highlighted the lack of uniqueness (or one-to-one correspondence) in the response of the B-based markers to the solute−solvent intermolecular interaction asymmetry, and therefore, their inadequacy as structure-making/breaking descriptors. Finally, we discuss the findings and provide a cautionary outlook on the use of the viscositybased structural markers.
