The crystallization phase diagrams for the MnSO4.H2O, MgSO4.7H2O solute in three different alcoholic aqueous solution (methanol, ethanol and 2-propanol) were calculated by the ion specific electrolyte NRTL model. We have discussed the salting-out effect of MgSO4 and solventing-out effects of three different of alcohols, and the synergy of MgSO4 and alcohol on the solubilitiy of MnSO4.H2O. We have represented the three dimensional figures as a function of temperature.
