Sodium sulfate anhydrous (CAS 7757-82-6)

Sodium sulfate anhydrous is a white, crystalline solid. Sodium sulfate anhydrous lacks water molecules in its structure, distinguishing it from the hydrated form of sodium sulfate. This chemical compound finds extensive use in laboratories and industries due to its versatile properties. It is employed as a drying agent, desiccant, and as a reagent in chemical reactions. Sodium sulfate anhydrous is soluble in water and has a high melting point, which makes it suitable for use in high-temperature processes. Scientifically, sodium sulfate anhydrous plays a vital role in analytical chemistry. It is utilized in gravimetric analysis to precipitate barium ions as barium sulfate, which is insoluble in water. This property allows for the determination of sulfate ion concentrations in various samples. Additionally, it is employed in the synthesis of other chemical compounds and in research involving crystallography and material sciences. The mechanism of action of sodium sulfate anhydrous is primarily attributed to its ability to act as a dehydrating agent. It readily absorbs water from its surroundings, making it effective in removing moisture or water content from substances. This property is in maintaining the purity and stability of certain chemical compounds, as well as facilitating the preservation of various materials. Anhydrous sodium sulfate occurs in arid environments as the mineral thenardite however the decahydrate (sc-203405) is the most abundant natural form and is derived from the mineral, mirabilite, often found in lake beds.
