The limiting partial molar volume and transfer partial molar volume of glycylglycine in aqueous sodium halide solutions at 298.15K and 308.15K

Effect of tri-potassium phosphate on volumetric, acoustic, and transport behaviour of aqueous solutions of 1-ethyl-3-methylimidazolium bromide at T=(298.15 to 318.15)K

“…Thus the overlap of two hydrophobic hydration cospheres releases some water molecules from the salvation sphere to the bulk, which gives rise to a negative change in volume. In contrast, for polar species the volume of water molecules is smaller in the solvate sphere due to: (1) the effect of electrostriction and (2) the decrease of hydrogen-bonded network with water molecules in the solvate sphere transferring to the bulk [29]. So the overlap of two hydrophilic hydration cospheres releases some water molecules to the bulk giving rise to a positive change in volume.…”

Effects of phosphate-based monobasic and tribasic inorganic salts on hydration characteristics of saccharides and their derivatives

“…The positive transfer volumes for saccharides in aqueous electrolyte solutions have also been explained through the 'electrostriction phenomenon' [48,49]. Ions are regarded kosmotropic (structure makers) or chaotropic (structure breakers) depending on their relative abilities to interact with water and to change the water structure by shifting the equilibrium of low-and high-density water (which is more and less structured, respectively).…”

How Different Electrolytes Can Influence the Aqueous Solution Behavior of 1-Ethyl-3-Methylimidazolium Chloride: A Volumetric, Viscometric, and Infrared Spectroscopy Approach

“…In the systems in which type 3 interactions are dominant, the limiting molar volumes of transfer are negative. According to the co-sphere overlap model, the overlap of two co-spheres of hydrophobic and ionic hydration releases some water molecule from the solvation sphere to the bulk that leads to a negative volume contribution ( Scheme 1 ) (Friedman and Krishnan, 1973 ; Lin et al, 2006 ).…”

“…The limiting apparent molar expansibility along with limiting apparent molar volume was used to determine the isobaric thermal expansion coefficient (α P ) through Equation (8). SCHEME 1 | The interaction of two co-spheres (Lin et al, 2006).…”
