<Dd> Na SO + H SO ⇌ 2 NaHSO </Dd> <P> The equilibrium constant for this process depends on concentration and temperature . </P> <P> Sodium sulfate has unusual solubility characteristics in water . Its solubility in water rises more than tenfold between 0 ° C to 32.384 ° C, where it reaches a maximum of 49.7 g / 100 mL . At this point the solubility curve changes slope, and the solubility becomes almost independent of temperature . This temperature at 32.384 ° C, corresponding to the release of crystal water and melting of the hydrated salt, serves as an accurate temperature reference for thermometer calibration . </P> <P> Sodium sulfate is a typical electrostatically bonded ionic sulfate, containing Na ions and SO ions . The existence of sulfate in solution is indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba or Pb salts: </P>
