Abstract

The solubility of Glutaric acid in water, ethanol and water + ethanol binary solvent was determined over the entire composition range between 0 to 1 weight fraction of ethanol at (293.15, 295.15, 298.15, 300.15, 303.15, 305.15, 308.15, and 313.15) K. The Apelblat and van't Hoff equation was used to correlate the experimental solubility data and the equations provide better correlation in this study. The activity coefficients were calculated to evaluate molecular solute-solvent interaction. DFT was carried out to correlate solubility in various solvents system. Thermodynamic properties (%ζH, %ζTS) of solution were calculated using van't Hoff equation.
