Iron(II) sulfate anhydrous is an inorganic compound composed of iron and sulfate ions, commonly used in water treatment, agriculture, and chemical synthesis.
🏭⚗️ Production
It is produced industrially by the oxidation of iron in the presence of sulfuric acid, followed by drying to obtain the anhydrous form. In laboratory settings, it can be prepared by reacting iron metal with dilute sulfuric acid and careful drying to remove water of crystallization.
🔬 Properties
Iron(II) sulfate anhydrous appears as a pale green to white crystalline solid, with chemical formula FeSO₄ and a molar mass of approximately 151.91 g/mol. It is soluble in water but oxidizes easily to iron(III) sulfate when exposed to air and moisture.
🧪 Applications
It is used in water purification, as a reducing agent in chemical reactions, and in agriculture as a soil amendment to correct iron deficiencies. It also finds applications in dyeing and as a precursor for other iron compounds.
⚠️ Safety
Iron(II) sulfate anhydrous should be handled with care, as it can cause irritation to skin, eyes, and respiratory tract. It should be stored in airtight containers in a cool, dry place away from oxidizing agents to prevent oxidation.
