Abstract
Physical properties such as density (ρ), sound speed (u) and viscosity (η) for varied compositions of a saccharide (sucrose) in water and mixed aqueous tributylmethylammonium chloride solvent media has been scrutinised at five discrete temperatures ranging (293.15 K - 313.15 K) and under ambient pressure (101.3 kPa). The empirically procured data has been employed to enumerate different volumetric, acoustic and viscometric parameters like apparent molar parameters (Kϕ,s, Vϕ), partial molar parameters (K0ϕ,s, V0ϕ), transfer parameters (K0ϕ,s,tr, V0ϕ,tr, Btr), hydration number, pair and triplet interaction coefficients, solvation number, viscosity B-coefficient etc. The temperature derivative of viscosity B-coefficient i.e. dB/dT values have been utilized to examine structure making ability of the solute. Also, Gibbs free energy of activation for both solute and solvent has been determined and the influence of temperature on the solute-solvent interactions has been addressed. Moreover, the co-sphere overlap model has been employed for better comprehension of various prevalent intermolecular interactions in the considered systems.
