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 6

Differences in values of muscovite precipitation and water dissociation reactions, obtained from different thermodynamic models: (a and b) full lines—difference between IAPWS95 and HGK84, and dashed lines—between IAPWS95 and ZD05 models for calculating water volumetric properties, using FE97 for water dielectric properties; (c and d) full lines—difference between FE97 and JN91, and dashed lines—between FE97 and SV14 models for calculating water dielectric properties, using IAPWS95 for water volumetric properties. A vertical dashed line at 500°C is shown on (c and d).
