Sodium sulfate is an inorganic salt composed of sodium and sulfate ions. It naturally occurs as the mineral mirabilite (in its hydrated form) and is commonly obtained synthetically by reacting sodium carbonate with sulfuric acid. It is highly soluble in water and widely used in various industrial processes.

Chemical and Physical Properties

• Density: ~2.66 g/cm³ (anhydrous)

• Melting Point: ~884°C

• Boiling Point: Decomposes

• Solubility in Water: 195 g/L at 20°C

• Solubility in Other Solvents: Insoluble in ethanol

• Odor: Odorless
