Solution Properties of Folic Acid/Nicotinic Acid in Aqueous 1-Butyl-3-methylimidazolium-chloride Media at Discrete Concentrations and Temperatures: A Thermodynamic, Computational, and Spectroscopic Study

“…In general, the limiting apparent molar volume can be regarded as the sum of various other volumes , which is revealed by the expression specified as follows: V ϕ o = V vw + V void − V shrinkage where V vw denotes the van der Waal’s volume of the taken solute, V shrinkage denotes the shrinkage/depreciation volume of the solute arising as a result of interactions governing vitamin and water molecules and V void is the volume occupied by voids in the studied solutions. Also, it has been perceived that the involvement of V vw and V void is equivalent in water, as well as in IL media.…”

“…For the solution systems of both vitamins, the deduced transfer values are manifested in Table S1 (ESI) which are found to be positive at all of the aforesaid temperatures. In general, the limiting apparent molar volume can be regarded as the sum of various other volumes 42,43 which is revealed by the expression specified as follows:…”

A Comprehensive Study on Molecular Interactions of l-Ascorbic Acid/Nicotinic Acid in Aqueous [BMIm]Br at Varying Temperatures and Compositions: Spectroscopic and Thermodynamic Insights

“…The viscosity of the mixture is related to its concentration (molarity) at all temperatures by the expression called the Jones–Dole expression as follows Here, A signifies the Falkenhagen coefficient, B signifies the viscosity B -coefficient, C is the molarity of the solution, η is the viscosity of the solution, η 0 is the viscosity of the pure solvent, and is the relative viscosity of the solution (η r ). The Falkenhagen coefficient, A , is a measure of various sorts of solute–solute interactions, , while the viscosity B -coefficient describes the nature of solute–solvent interactions, , which is in turn reliant on the size and structure of the solute molecules . The viscosity B -coefficient furnishes information about the solvation behavior of the solute and solvent organization in the presence of the solute, i.e., it is a measure of vitamin–ionic liquid interactions.…”

Explorations on Solute–Solvent Interactions of Tripotassium Citrate and Sodium Benzoate in Aqueous 1-Ethyl-3-methylimidazolium Ethyl Sulfate Solutions: Physicochemical, Spectroscopic, and Computational Approaches

“…V ϕ 0 values have been assessed using the following equation where V ϕ 0 is the partial molar volume at infinite dilution that indicates the occurrence of the solute−solvent interactions in the systems and S v is the Debye−Huckel limiting slope that implies the extent of the solute−solute interactions. 33 The plots of V ϕ against √m for the solute in water and aqueous IL solutions at 293.15−313.15 K are represented by the linear graphs in Figures 2 and S2. In Table S1, the values of V ϕ 0 and S v are displayed along with their standard deviations.…”
