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

<div>Mineral solubility in water as a function of temperature at 2 kbar, calculated using the JN91, SV14, and FE97 models for water dielectric properties and IAPWS95 for water volumetric properties: (a) calcite solubility, (b) muscovite solubility, and (c) wollastonite + quartz solubility; (a, b, c) in pure water at 2 kbar with varying temperature; (d) enstatite + forsterite solubility in NaCl solution of varying molality at 700°C and 4 kbar. Total amounts of dissolved elements as well as the species concentrations and negative pH are shown. Symbols represent element concentrations measured in experiments.</div>
