Using thermodynamic values from Misra appendix 5, NOT R&H95, write reactions that solubilize hematite (Fe2O3) to Fe3+, FeOH 2+, Fe(OH)2+ and Fe(OH)3(aq), then construct a solubility diagram depicting hematite solubility relations as a function of (x-axis) pH from 0 to 10, and (y-axis) activity of aqueous Fe(III) species in the system. Diagram includes all reaction lines for all species. (1 pt) Diagram includes correctly calculated values for reaction lines. (1 pt). Diagram includes readable labels for hematite and all aqueous Fe(III) species, both axes, and axis numerical values. (1 pt)
