Applications
OccurrenceSodium sulfate occurs in nature as the minerals mirabilite and thenardite. While thenardite is the anhydrous form of Na2SO4, mirabilite is a naturallyoccurring decahydrate, Na2SO4•10H2O. Sodium sulfate is one of the most important sodium salts. The decahydrate,commonly known as the Glauber’s salt, was first prepared by Johann Glauber in the seventeenth century as a by-product in making hydrochloric acid from sulfuric acid and sodium chloride.
UsesSodium sulfate decahydrate is used as a laboratory reagent to precipitate protein. It is largely used as filler in powdered home laundry detergents. It facilitates in leveling, reducing negative charges on fibers, thereby allows dye to penetrate evenly. It avoids the corrosion of stainless steel vessels used in dyeing. It is also used as a laxative and effectively replaces the drug paracetamol in the body.
UsesSodium sulfate decahydrate may be used to deepen the color while dyeing cotton fabrics.6
UsesSodium sulfate decahydrate is used in manufacturing paper pulp by the Kraft Process. Other uses are in manufacturing glass and ultramarine; in dyeing and printing textiles; as a filler in synthetic detergents; and for standardizing dyes. A major use of anhydrous sodium sulfate is as an agent to remove water from organic solvents and their extracts for organic synthesis and instrumental analysis. Sodium sulfate decahydrate is a common laboratory reagent. Also, it is used to prepare other sodium salts.
General DescriptionSodium sulfate decahydrate (Glauber′s salt, mirabilite, Na2SO4·10H2O) is the decahydrate salt of sodium sulfate. Its crystal structure has been investigated by single-crystal neutron diffraction studies. Its crystallization enthalpy has been evaluated. It can be synthesized by reacting MnSO4, thiophene-2,5-dicarboxylic acid and sodium glutamate.
