The initial mole fraction of CO2(aq) is 0.185. The pressure is ~10 GPa. The temperatures are a 1000 K and b 1400 K. The data of bulk solutions in (a) are from ref. 10, and the bulk data in (b) were interpolated using the simulation results in ref. 10. Uncertainties were obtained using the blocking method68.
