Usage
Sodium sulfate has unusual solubility characteristics in water.[9] 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. Sodium sulfate is a typical electrostatically bonded ionic sulfate, containing Na+ ions and SO42â ions. The existence of sulfate in solution is indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba2+ or Pb2+ salts: Na2SO4 + BaCl2 â 2 NaCl + BaSO4

Product Description

Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na₂SO₄ as well as several related hydrates. All forms are white solids that are highly soluble in water.

Sodium Sulfate, Anhydrous is chemically very stable, and is unreactive toward most oxidizing or reducing agents at normal temperatures. It is a neutral salt and will form aqueous solutions with a ph of ~7. Anhydrous sodium sulfate occurs in arid environments as the mineral thenardite; however the decahydrate (sc-203405) is the most abundant natural form and is derived from the mineral, mirabilite, often found in lake beds. Anhydrous sodium sulfate is used in the laboratory as an inert drying agent for removing traces of water from organic solutions. It is only effective below 30°C, but is fairly inert and can be used with a variety of materials.
