The Ternary System K2SO4-MnSO4-H2O at 20C,

Abstract : The solubility isotherm of the system potassium sulfate-manganese sulfate-water at 20 degrees centigrade was studied. The electrical conductivity, density, and viscosity of equilibrium saturated solutions of the given system were determined. It was shown that the sulfate salts of potassium and manganese together with the known binary salt potassium sulfate-manganese sulfate-water form solid solutions based on the monohydrate of manganese sulfate.
