Application of the Pierotti Approach in Calculation of the Solubility of Nonelectrolytes in Water-Acid Systems
Abstract
Based on the experimental values on the solubility of noble gases, nitrogen, oxygen, hydrogen, and a number of hydrocarbons, the possibility of application of the Pierotti approach to predict the solubility of nonelectrolytes in water, acetic acid, inorganic acids, and water-acid mixed solvents over the entire range of their composition was analyzed. The parameters of the Lennard-Jones potential for sulfuric and nitric acids are calculated for the first time. This approach makes it possible to quantitatively predict the solubility of a wide number of nonelectrolytes, including C5-C8 hydrocarbons, in sulfuric and nitric acids and to quantitatively calculate the solubility of small molecules and qualitatively calculate that of long-chain hydrocarbons in acetic acid. In the case of aqueous solutions of hydrocarbons, however, the Pierotti approach fails to predict solubility even at a qualitative level.
