Thermodynamic Parameters for solvation of Copper sulphate in (ethanol-water) mixed solvent at different temperatures
Journal Title: Asian Journal of Nanoscience and Materials - Year 2018, Vol 1, Issue 2
Abstract
The measurements of copper sulphate conductance have happened in binary mixed solvent with ethanol in different mass fraction 0%, 20% and 40% (W/W) (EtOH-H2O) at four different temperatures from 298.15 to 313.15o K (with a step of 5o K). The experimental data obtained by using the Fuoss-Shedlovsky extrapolation technique. All thermodynamic parameters for association were calculated. This parameters such as molar conductance (Λm), limiting molar conductance (Λ0), Walden product (Λ0 η0), ion-pair association constant (KA), the activation energy for the transport process (Ea) and also the standerd thermodynamic prameters for association (∆GoA, ∆HoA and ∆SoA). Although we studied the effect of hydrogen bond formation in solution. The results estimated show that the association constant was increased with increasing temperature while the molar conductance and the limiting molar conductance values were decreased. Furthermore, all the association constant values were increased indicating that the association process is endothermic.
