Abstract
Densities and Ultrasonic velocities of glycerin and dextrose in Na2CO3 and NaHCO3 buffer solutions have been determined experimentally at 308 and 313K. From these experimental results the adiabatic compressibility Ks, acoustic impedance Z, intermolecular free length Lf, relative association RA, available volume Va and hydration number Hn 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.
