Keywords:
Specific Viscosity, Density, Thermodynamic Parameters, Thermodynamic Parameters ?G, ?S and ?H, Chloride Salt of Ca2+, Mn2+ & Ni2+.Abstract
The physical properties such as densities, specific viscosities of CaCl2, MnCl2 and NiCl2 at different concentration in the range (1x10-2 M to 6x10-4 M) in aqueous medium at temperature 299K, 305K and 311K are reported. The experimental data shows, the effect of concentration of solute on viscosity in aqueous medium which gives idea about the molecular interactions present in different solutions. Appreciable molecular interactions have been observed between the Chloride salt of Ca2+, Mn2+ & Ni2+ and water. The thermodynamic parameters ?G, ?S and ?H for the dissolution of CaCl2, MnCl2 and NiCl2 were calculated from values of viscosity and densities at different temperatures such as 299K, 305K and 311K in aqueous medium. The experimental data gives the idea about effect of temperature on the molecular interaction and structural changes in solute.
