Investigation on molecular interactions of nicotinamide in aqueous citric acid monohydrate solutions with reference to manifestation of partial molar volume and viscosity B-coefficient measurements

Effect of ionic liquid, 1-hexyl-3-methylimidazolium bromide on the volumetric, acoustic and viscometric behavior of aqueous sucrose solutions at different temperatures

“…, (13) whereη and 0 η are viscosities of the solution and the solvent, respectivelyand B is experimental viscosity coefficient. The viscosity B-coefficient determined by fitting viscosity data is a measure of structural modifications induced by the solute-cosolute interactions [53]. [54] and again good agreement is obtained except at T = 308.15 K in which our value is slightly higher than the one reported in the literature [54].…”

Influence of Imidazolium Ionic Liquids on the Interactions of Human Hemoglobin with DyCl3, ErCl3, and YbCl3 in Aqueous Citric Acid at T = (298.15, 303.15, and 308.15) K and 0.1 MPa

“…Density (ρ/10 3 kg•m −3 ). Table S3 of the Supporting Information compares the density of 0.005 mol•kg −1 aqueous anhydrous citric acid with that of aqueous citric acid monohydrate, reported by Roy et al, 59 using linear regression analysis. The values deviate from each other by 0.013% and 0.016% at 298.15 and 308.15 K, respectively, as reported earlier by Parmar et al, where they have shown that, the removal of water of crystallization changes the behavior of solute in the solution.…”

“…Viscosity (η/10 −3 kg•m −1 •s −1 ). Table S3 of Supporting Information compares the viscosity of 0.005 mol•kg −1 aqueous anhydrous citric acid with that of aqueous citric acid monohydrate, reported by Roy et al, 59 using linear regression analysis, The viscosity value differs from our value by 4.53% and 0.02% at 298.15 and 308.15 K respectively, which may be due to the water of crystallization present in the citric acid monohydrate, thereby changing the behavior of citric acid in the solution. 60 Viscosity is a flow property of liquid, which directly reflects the interacting strength of LnCl 3 with H 3 Cit, Hgb, and ILs in aqueous medium.…”

Viscosity of Ammonium Nitrate + Formamide Mixtures

“…In Figure the reduced viscosity dependence of the ammonium nitrate concentration is presented. The coefficient A depends on the long-range Coulombic interactions between the ions, and it is observed that these A values are negative, indicating very weak ion–ion interactions. , The coefficient B is a function of viscosity effects as Coulombic interaction, size, and shape of effects or Einstein effect, orientation of polar molecules in the ionic field, and distortion of the solvent structure. The positive values of the coefficient B indicate strong ion–solvent interactions and structure-making effect (ions ordering) in the system .…”
