Abstract
The solubility of aqueous manganese sulfate monohydrate has been measured in the presence of magnesium sulfate as the second salt. Over the temperature range from 273 to 353 K, aqueous manganese sulfate on its own exhibited an unusual behavior in that its solubility reached a maximum at an intermediate temperature of 293K. The solubilities of manganese sulphate under and over the maximum solubility temperature were first predicted individually by the electrolyte NRTL model. The binary interaction parameters and solubility parameters were universal parameters that were applied to any salts consisting of manganese, magnesium and sulfate ions, and they were newly obtained from the binary solubility data. The predicted solubility curves could represent the experimental data quantitatively, and adequately described the effect of co-salt of magnesium. The experimental solubility data were also satisfactorily correlated with the electrolyte NRTL model.
