The Gibbs free energies as very important thermodynamic property were evaluated for Pb(NO3)2 in mixed Acetone-H2O solvents at different temperature from the experimental solubility measurements. The ratio of the ionic between lead and nitrate ions was used to divide the total Gibbs free energy of the salt into its individual contribution in the mixtures used. The conventional Gibbs free energies for the cation (Pb2+) and anion (NO- 3) were estimated theoretically and also the Gibbs free energy of NO- 3 gas was evaluated and their values were discussed.
