It is produce industrially by the reaction of magnesium sulfate and sodium chloride in solution followed by crystallization. In both cases, Sodium sulfate is subsequently crystallised as the decahydrate product which can easily convert to anhydrous form upon heating.
Applications:
It is also called Glaubber Salt.
Because of its moisture-adsorbing ability, the anhydrous salt is used for drying certain organic liquids. The loose, granular anhydrous solids changed to the hydrated from which is lumped together. It is also used in the Kjeldahl method of nitrogen determination.
It is also used in the manufacture of glass, paper pulp, paper board, and as a raw material for the production of various chemicals. Sodium sulfate is also used as a filler and extender in dry powder, laundry and dishwashing detergent products.
In textile industry, the anhydrous salt is added to the dye bath to drive the dye from the solution onto the fibers and to promote an even finish.
