Abstract
Ultrasonic velocity (U), viscocity (η) and density (ρ) ofL- ascorbic acid, dextrose and sucrose in aqueous guanidine hydrochloride (0.3 m) have been measured at 298.15 K. The derived acoustical parameters namely adiabatic compressibility (β), apparent molal compressibility (ΨK) apparent molal volume (ΨV) limiting apparent molal compressibility (Ψ0K) limiting apparent molal volume (Ψ0V) and their constants (SK, Sv) and viscosityB- coefficient and hydration number (nH) have been computed from the experimental data. The variation of these parameters with respect to the molality of solutes have been explained on the basis of solute-solvent interaction and structure making tendency of the solutes in solvents.
Highlights
Ultrasonic investigation provides an extensive application in characterizing thermodynamic and physicochemical behavior of liquid mixtures
Molecular interactions are responsible for the observed increase in ultrasonic velocity in these mixtures
The present study reports experimental data for density, viscosity and ultrasonic velocity at 298.15K for L-ascorbic acid, dextrose and sucrose in aqueous guanidine hydrochloride mixture
Summary
Ultrasonic investigation provides an extensive application in characterizing thermodynamic and physicochemical behavior of liquid mixtures. During the last two decades, the ultrasonic study of the carbohydrates in aqueous electrolytic medium, has gained much importance in assessing the nature of molecular interaction present in the mixture.
