The stable phase equilibria of the ternary system NaBr−Na2SO4H2O at 273.2 K and 308.2 K were determined using the isothermal dissolution equilibrium method. The phase diagrams of the ternary system at different temperatures were plotted using the solubility of each salt in the equilibrium liquid pha...
