Investigation of Solution Behaviour of Potassium Halides in Aqueous Solution of L- Proline at Different Temperatures: A Physicochemical Approach

Exploring Various Molecular Interactions of Two Essential Amino Acids Prevalent in Aqueous Solutions of an Ionic Liquid by Density, Viscosity, Refractive Index, Conductance, Surface Tension, Nuclear Magnetic Resonance, Ultraviolet, and Computational Studies

“…From Table and Figure , we can observe that all the values of ϕ v 0 are positive, which further increase with increasing temperature as well as the molality. ϕ v 0 is sensitive to solute–solvent interaction in an aqueous medium and provides information regarding the structural volume of solute in solvent media and volume change of solvent during the shell formation surrounding the ions . It is found that ϕ v 0 values are higher for the l -leucine system compared with the l -valine system, indicating that more hydration of ions in the case of l -leucine undergoes greater interactions.…”

Values of S v * decrease with increasing temperature as well as molality, indicating a poor solute−solute interaction.…”
