The physicochemical properties were evaluated by measuring the densities, sound speeds, conductance, and viscosity values for aqueous solutions of aspirin with varying concentrations (0.001–0.010) mol kg–1 at four distinct temperatures (300.15–315.15) K. The experimental data was further used to calculate various physicochemical parameters. On increasing temperature, the values of ΦvO increased from 126.83 to 134.50 and ΦKO increased from −6.77 to −3.45, suggesting strong drug–water interactions. A similar trend prevailed in ΦEO, revealing the presence of the caging effect and structure-making behavior of aspirin. Moreover, hyperchromic shift in UV–visible spectrum, quenching in fluorescence spectra, and shift in FTIR spectrum (recorded at T/K = 298.15 and P/MPa = 0.1) strongly validate and strengthen the results of strong intermolecular interactions derived from the physicochemical data. The cyclic voltammetry technique was employed to investigate the electrochemical response of aspirin.

For a deeper understanding of structural interactions, it is essential to have accurate physiochemical data on the imidazolium-based IL and biopolymer model compound (d-glucose) in aqueous solutions. In this regard, we studied the volumetric and compressibility properties of d-glucose in aqueous and aqueous 0.05, 0.10, and 0.15 mol·kg–1 1-methyl imidazole trifluoromethanesulfonate [MIm][OTf] ionic liquid solutions at various concentrations and temperatures. The limiting apparent molar volume of the solute (Vϕ0) and compressibility of the solute (KS,ϕ0) properties were used to interpret the strength and extent of solute–solvent interactions in the studied systems. The observed increase in Vϕ0 and KS,ϕ0 with temperature and [MIm][OTf] concentration suggests the dehydration effect of [MIm][OTf] on d-glucose solutions. Moreover, to study the potential solute-co-solute interactions, transfer volume (ΔtrVϕ0) and transfer compressibility (ΔtrKs,ϕ0) have been computed. The positive outcome of ΔtrVϕ0 and ΔtrKs,ϕ0 data reveals the dominance of hydrophilic-cation interactions. The kosmotropic nature of d-glucose in aqueous [MIm][OTf] solutions is confirmed by the positive Hepler’s constant values.

Least squares fitting was employed to determine coefficients for density, speed of sound, thermal expansion, apparent molar volume, isentropic compressibility, and apparent molar isentropic compressibility. The thermal expansion coefficient (α), reflecting the temperature dependence of densities, was evaluated and analyzed alongside apparent molar expansibility (VE).

The SKTP solubility increased with decreasing water content in alcohols–water but exhibited cosolvency at w = 0.80 in acetone–water; the maximum mole fraction solubility is 0.1072.

The solvent effect analysis showed that solute–solvent or solvent–solvent interactions account for 63.44 and 32.60% of solvent effect.
