Parity plot of the predicted versus reference values of ln γ ∞ i,j using the SM12 universal solvent model for the case where water was the solvent, water was the solute, and where water was neither the solvent or solute, as indicated. The blue lines corresponds to the y = x line, and the dashed blue lines correspond to ±1.1 and are drawn as a reference. The reference values are from DECHEMA. In the top pane we present results when ∆G self i,i was predicted using the SM12 universal solvent model. In the bottom pane we present results when ∆G self i,i was computed using reference vapor pressure data.
