Chabab et al. measured the solubility of oxygen up to 350 bar and 100⁰C in water and NaCl aqueous solutions. Figure shows the models' prediction along the solubility measurements in water (panel a), 1 m (panel b), and 4 m NaCl (panel c). Analogous to H2, PHREEQC and Reaktoro predict correctly the solubility of oxygen at high salinity only when "phreeqc.dat" is used.
