• Why does sodium sulfate have an unusual solubility

    For many salts there are solubility curves as a function of temperature that are smooth (don't have any kinks). Sodium sulfate, however, has a kink in the solubility-T curve at 30 degrees as shown

    What is Sodium Sulfate? Definition from Corrosionpedia

    Sodium sulfate is chemically very stable, being nonreactive toward most oxidizing or reducing agents at normal temperatures. At high temperatures, it can be converted to sodium sulfide by carbothermal reduction. It causes hot corrosion, which is the degradation of materials caused by the presence of a deposit or ash, predominantly sodium
