Study of Solute-solute and Solute-solventInteraction of Glycerin and Dextrose in BufferSolutions at Different Temperature by UsingVolumetric and Acoustic Methods

摘要

Densities and Ultrasonic velocities of glycerin and dextrose in Na_(2)CO_(3) and NaHCO_(3) buffer solutions have been determined experimentally at 308 and 313K. From these experimental results the adiabatic compressibility K_(s), acoustic impedance Z, intermolecular free length L_(f), relative association R_(A), available volume V_(a) and hydration number H_(n) have been calculated. The results are interpreted in terms of solute-solute and solute-solvent interactions in these ternary systems. It has been observed that there exist solute-solvent interaction and complex formation between in these ternary systems.
