文摘

Measuring surface tension and density of aqueous VOSO4 for T: 283.15–313.15 K. A new definition of molar surface Gibbs free energy, gs, was proposed. gs was used to predict the surface tension of the aqueous VOSO4. An improved Eötvös equation with a more explicit physical meaning was presented. Molar surface enthalpy and entropy were evaluated.
