Sodium sulfates are inorganic compounds with the chemical formula Na2SO4. They are typically found as white, crystalline solids and are highly soluble in water. Sodium sulfates are commonly used in various industries, including detergents, glass manufacturing, and as a drying agent in chemical processes. These compounds can occur naturally in mineral deposits, such as mirabilite, and can also be produced synthetically. Sodium sulfates play a role in the production of sodium sulfate decahydrate, which is used in laundry detergents and as a filler in various products.
