Sodium Sulphate By Meishan City Dongjiang Chemical Co., Ltd

Sodium Sulphate is a white, orthorhombic crystalline solid at room temperatures ( a monoclinic structure at > 100 C, a hexagonal structure at > 250C). Sodium Sulphate is reduced to sodium sulfide at high temperature. But sodium sulfate Anhydrous is a stable compound which does not decompose and does not react with oxidising or reducing agents at normal temperatures. It is neutral (pH of 7) in water. Sodium sulfate Anhydrous is most soluble in water at 32.4 C (49.7g/100 g). Commercial major source of sodium sulfate is salt cake (impure sodium sulfate), a by-product of hydrochloric acid production from sodium chloride by treatment with sulfuric acid. Sodium sulfate Anhydrous is obtained also as a by product of rayon production and sodium dichromate production.
