When standard database predicts precipitation of Fe(III), Zn(II), Cu(II) as Fe(OH)3, Zn(OH)2 and Cu(OH)2 respectively, Inclusion of the Corrosion database produces the more stable hematite Fe2O3, goethite FeO(OH), ZnO and CuO solids.
When you include a corrosion data bank, surely it predicts more stable oxides. That is because when a corrosion databank is included, the solver automatically assumes a surface rather than a simple solid precipitation. And then the speciation changes. The hydroxides are still considered a part of the system, but the possibility of oxides forming increases because there will be corroding surface involved in that system. Thus the stable oxide predictions.
