Physicochemical Investigation of Diverse Interactions of Some Biologically Potent Molecules Prevalent in Aqueous Ionic Liquid Solutions at Different Temperatures

ABSTRACT

Densities, viscosities, conductivity, and refractive indices of L-ascorbic acid in aqueous solutions of an ionic liquid,
1-butylpyridinium bromide, have been measured at five different temperatures ranging from 293.15K to 313.15K. Some
important parameters have been derived from the above physicochemical experiments, namely, limiting apparent molar volume (φV0) and viscosity B-coefficients using extended Masson equation and Jones-Dole equation, respectively. Lorentz-Lorenz equation has used to evaluate molar refractive index (RM) and limiting molar index (RM0). Specific conductivity measurement applied to ascertain ionic nature of the system.

Key words:  Solute-co-solute interactions, Apparent molar volume, Viscosity B-coefficient, Molar refraction, Conductivity study
