Products Description of Sodium sulfate CAS#7757-82-6
Sodium Sulfate(7757-82-6), Na2S04, additionally recognised as thenardite and salt cake, is a crystalline compound that melts at 888°C (1632°F). Sodium Sulfate is discovered in herbal form(thenardite) in Chile and Spain. It is used in the manufacture of paperboard, glass,and freezing mixtures. The hydrate, Na2S04·10H20, additionally regarded as "Glauber's salt," is a white water-soluble stable shaped by using heating Sodium chloride and sulfuric acid. It is used in dyeing,manufacturing glass,and in the practise of sodium bisulfate.
