Sodium Sulfate

Sodium sulfate is an inorganic compound with the chemical formula Na2SO4. It is a white crystalline solid that is highly soluble in water. Sodium sulfate is commonly used in various industrial applications, including as a filler in detergents and as a processing agent in the manufacture of paper and glass.

The compound can be produced through several methods, including the reaction of sodium hydroxide with sulfuric acid. Sodium sulfate forms two hydrates: anhydrous (without water) and decahydrate (with ten molecules of water). The decahydrate form is known as Glauber's salt and is a common source of the compound.

Sodium sulfate is relatively non-toxic and is considered safe for general use, although ingestion or inhalation of large amounts may cause irritation to the respiratory system or digestive tract. The compound has a melting point of 884°C and a boiling point of 1429°C.
