آیرون II سولفات

Iron (II) sulfate (chemical formula: FeSO₄), also known as ferrous sulfate, is an inorganic salt composed of iron and sulfate ions. It most commonly appears as blue-green crystals in its heptahydrate form and has been historically referred to as green vitriol.

🏭⚗️ Production
Iron (II) sulfate is typically produced as a byproduct of steel manufacturing when iron is treated with sulfuric acid. It can also be obtained from the oxidation of pyrite or as a secondary product in the pickling of iron or steel.

🔬 Properties
Iron (II) sulfate usually appears as pale green or blue-green crystalline solid in its heptahydrate form. It has a melting point around 64 °C (heptahydrate) and decomposes upon further heating. It is soluble in water, forming pale green solutions of the hexaaqua complex [Fe(H₂O)₆]²⁺. It is paramagnetic and slowly oxidizes in moist air to form iron (III) compounds, resulting in a yellowish or brown surface. The anhydrous form is a white powder.

🧪 Applications
• Medical: Used in iron supplements to treat iron-deficiency anemia.
• Agriculture: Applied to correct iron chlorosis in plants and as a soil amendment to reduce alkalinity.
• Water treatment: Used to remove phosphates and as a flocculant.
• Pigments and dyes: Historically used in ink production (iron gall ink) and as a mordant in dyeing.
• Industrial: Employed in the production of other iron compounds and as a reducing agent in chemical processes.
