|Abstract: ||Measurements of density, viscosity, ultrasonic
velocity and refractive index of L-aspartic acid (0.01-0.09 mol.L-1)
0.1 M, 0.05 M and 0.025 M aqueous zinc chloride and copper chloride solutions
have been carried out at 308.15 K to evaluate some important parameters, viz.
isentropic compressibility, relative association, free path length, apparent
molar volume, apparent molar isentropic compressibility and molar refraction.
These values are used to explain molecular association,
solute-solvent interaction through hydrogen bonding and solvation. Viscosity
data have been analyzed in the light of
Jones-Dole equation and the constants A and B are estimated.
The results have been interpreted in the light of various interactions occurring
between components of the mixtures under applied experimental conditions. The
aspartic acid has been found to be structure maker in aqueous zinc chloride and
copper chloride solutions from molar volume and as well as viscosity data.
