Sodium Sulphate Anhydrous 99% Na2SO4 CAS 7757-82-6 Glauber Salt
Sodium sulfate (chemical formula: Na2SO4) is a salt formed by the combination of sulfate and sodium ions.
Sodium sulfate is soluble in water and its aqueous solution is weakly alkaline. It is soluble in glycerin but not in ethanol. Exposure to air easily absorbs water to generate sodium sulfate decahydrate. At 241℃, sodium sulfate will transform into hexagonal crystals. Anhydrous sodium sulfate with high purity and fine particles is called sodium sulfate.
