The molar solubility of sodium oxalate (Na2Ox) in mixed ethanol (EtOH) – water solvent mixtures were measured at 301.15 K. From the
molar solubilities, the activity coefficients, solubility products, free energies of solvation and the transfer free energies for the interaction of
(Na2Ox) in mixed (EtOH-H2O) solvents were evaluated.
Key words: molar solubility, sodium oxalate, free energies of solvation, water and ethanol
