μ$/H2-X DIAGRAMS OF WATER-MINERAL SYSTEMS

Abstract

The present paper studies the effect of the pH2 on the solubility of minerals in terms of phase diagrams of μ$-H$(2)$/ (pH2) versus X (by analogy with the μH+ (pH)-X) diagrams discussed previously. As an example, the authors discuss the pH2 - X diagram for saturated water vapor. The free energy of formation of a particle of H2Sb2S40 (solution) was improved on the basis of new experimental data. The calculations for the diagrams were made by minimizing the free energy, using the SELEKTOR-BESM-6 program. Study methods and results are discussed.
