Sodium sulfate is a white, orthorhombic crystalline solid at room temperatures ( a monoclinic structure at > 100 C, a hexagonal structure at > 250C).
It is reduced to sodium sulfide at high temperature. But sodium sulfate 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 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 is obtained also as a byproduct of rayon production and sodium dichromate production.
The decahydrate is known as Glauber's salt. About half of the world's production is from the natural mineral form of the decahydrate (mirabilite). Anhydrous sodium sulfate is found in nature as the mineral thenardite (Na2SO4). Other sodium sulfate minerals are metasideronatrite Na4Fe2(SO4)4(OH)213H2O, krohnkite Na2Cu(SO4)212H2O, and schairerite Na3(SO4)(F,Cl).
Sodium sulfate is consumed in four major categories; powder ***ergents as a processing aid and as a filler, wood pulp processing for making kraft paper, textile dyeing processes as a levelling agent to penetrate evenly, and molten glass process to remove small air bubbles. Sodium sulfate is employed also as a raw material for the production of various chemicals.
