“…The viscosity values of MgCl 2 aqueous solutions agree quite well with those found in the literature. 26,28,29,39,40 A comparison of viscosities of MgCl 2 solutions at different temperatures is shown in Figures 1b and S5; small discrepancies between the present values and the literature values may be due to differences in methods of solution preparations, purity of materials used, etc. The solution viscosity, η (Table 3), increases with the concentration of bases of nucleic acids in water 25 and in MgCl 2 aqueous solutions but decreases with an increase in temperature.…”

“…The larger is the molar weight of the amino acid, the slower is the motion of the molecule, and naturally the larger is the viscosity. Viscosity B coefficient is a valuable parameter regarding the solute–solvent interactions. , It could be clearly observed from Table that the viscosity B coefficients are positive for these amino acids and retain an increasing trend with the molality of vitamin B6, implying the existence of strong solute–solvent interactions in the presence of vitamin B6. Additionally, the relationship between the viscosity B coefficient and temperature, expressed as the derivative form of d B /d T , could provide more information about the solute–solvent interactions in terms of the structure-making and structure-breaking nature.…”

The densities and viscosities of glycine, l-alanine, l-valine, l-threonine, and l-arginine in (0.1 to 0.4) mol·kg–1 vitamin B6 aqueous solutions were measured and studied over the entire molality range at (293.15, 303.15, 313.15, and 323.15) K and atmospheric pressure. The apparent molar volume (V ϕ), limiting partial molar volume (V ϕ 0), and limiting partial molar volume of transfer (Δtr V ϕ 0) were obtained according to the experimental density data. The viscosity data were employed to determine the viscosity B coefficients, the free energies of activation per mole of solvent (Δμ1 0⇌) and solute (Δμ2 0⇌). The influences of temperature, molality, and solute structure on these parameters were discussed in terms of molecular interactions. The contributions of the charged end group (NH3 +, COO–) and CH2 group to the limiting partial molar volumes and viscosity B coefficients were obtained through their linear correlation as a function of the number of carbon atoms in the alkyl chains of the studied amino acids.

“…Consequently, these criteria cannot be taken as markers of structure-making/breaking trends despite their widespread use in the literature. Notably, despite the lack of an explicit link to any actual microstructural feature of the solutions under study, the structure-making/breaking criterion around the sign of (∂ B /∂ T ) P has been regularly used in combination with, or as a complement to, the isobaric expansivity-based criterion for the structure-making/breaking ability of infinitely dilute solutes, as attested by a representative sample of the relevant literature. − …”

We analyzed the consistency, or lack thereof, of the conjectured connection between the sign of Jones−Dole's Bcoefficient, or its isobaric-temperature derivative, and the structure-making/breaking ability of a solute in a dilute solution. We sought to shed light on some crucial issues, including (i) whether Jones−Dole's B-coefficient contains any embedded microstructural information, (ii) whether we can either assign any definite foundation to the widely used assumption about the sign of the Bcoefficient and its structure-making/breaking trend or provide a rational justification for its use as a structure-making/breaking marker, and (iii) whether we actually need Jones−Dole's B-coefficient and its isobaric-temperature derivative as markers for the interpretation of structure-making/breaking trends. Thus, we first addressed the fundamental (statistical mechanical) microscopic to (thermodynamic) macroscopic foundations of a rigorous approach to the structure-making/breaking ability of a solute, regardless of the type of solvent or nature of the solute−solvent intermolecular interaction asymmetries, and its exact relationships to the resulting solution thermodynamics. Then, we derived the required conditions for the signs of the B-coefficient and/or its isobaric-temperature derivative to describe either a structure-making or a structure-breaking event, according to the actual solute-induced perturbation of the solvent microstructure, and consequently, tested the rationale underlying the B-based conjectured structure-making/breaking markers. Moreover, we invoked a well-known transition-state (TS) interpretation of the B-coefficient to connect it explicitly to the derived molecular-based structure-making/breaking signature and to find under which TS conditions the signs of the B-coefficient and its temperature derivative could describe the actual solute-induced perturbation of the solvent microstructure. We illustrated the actual structure-making/breaking behavior for a series of aqueous solutes over a wide range of solute−solvent intermolecular interaction asymmetries and compared their behavior against that predicted by Jones−Dole's based markers. This comparison, supported by rigorous thermodynamic arguments, highlighted the lack of uniqueness (or one-to-one correspondence) in the response of the B-based markers to the solute−solvent intermolecular interaction asymmetry, and therefore, their inadequacy as structure-making/breaking descriptors. Finally, we discuss the findings and provide a cautionary outlook on the use of the viscositybased structural markers.
