Thermodynamic Properties of Aqueous Species Calculated Using the HKF Model: How Do Different Thermodynamic and Electrostatic Models for Solvent Water Affect Calculated Aqueous Properties?

Figure 9

Calculated composition of an aqueous solution in equilibrium with albite, K-feldspar, andalusite, and quartz at 650°C, 2 kbar, with increasing Cl concentration, using the JN91, SV14, and FE97 models for water dielectric properties and IAPWS95 for water volumetric properties. (a) Total amounts of Na, K, Si, and Al compared with experimental data [86]; (b) amounts of various chemical species for each element. Calculations done with SV14 overlap those done with FE97.
