ABSTRACT:

Density (r), viscosity (h) and ultrasonic velocity (U) of ammonium chloride, copper chloride and magnesium chloride + aqueous ethanol solution (1m) have been measured at 303, 308, 313K. The derived thermodynamical and transport parameters namely adiabatic compressibility (b), hydration number (nH), apparent molal compressibility (), apparent molal volume (), limiting apparent molal compressibility (), limiting apparent molal volume () and their constants (SK, SV), viscosity B-coefficient of Jones-Dole equation have been computed from the experimental data. The results have been explained on the basis of ion-solvent interaction and structure intensifying property of the solutes in the solvent mixture.

KEYWORDS: ultrasonic velocity; apparent molar volume; hydration number
