Phase diagram for sodium sulfate. The solid lines are equilibrium phase boundaries, and the dashed line is the metastable extension of the thenardite-solution boundary and therefore represents solution compositions in metastable equilibrium with thenardite but supersaturated with respect to mirabilite (after Flatt 2002)
The labeled areas in the phase diagram. These areas all show what you would see if you had a particular mixture of salt and water at a given temperature. For example, if the temperature was below -21.1°C, you would always see a mixture of solid salt and ice. There would never be any liquid whatever proportions of salt and water you had.
