| Abstract: | The
density and viscosity of halides of potassium, sodium and ammonium have been
measured in different aqueous solutions of dextran at 298.15, 303.15, 308.15
and 313.15 K and the ultrasonic velocity in these solutions has been measured
at 298.15 K. Various parameters such as isentropic compressibility, acoustic impedance,
apparent molar volume, partial molar volume, relative association and
relaxation time have been calculated using experimentally determined values of
ultrasonic velocity and density. The variation of these parameters has been
discussed in the light of solute-solvent and solute-solute interactions. The
viscosity data have been analyzed on the basis of Jones-Dole equation to
interpret the ion-solvent interactions. |
