Iron(II) chloride tetrahydrate is an inorganic compound consisting of iron(II) ions and chloride ions, commonly used as a reducing agent and in water treatment.
🏭⚗️ Production
It is produced industrially by dissolving iron metal in hydrochloric acid or by reducing iron(III) chloride. In laboratory or pharmaceutical settings, it is typically prepared by direct reaction of iron powder with hydrochloric acid, followed by crystallization to obtain the tetrahydrate form.
🔬 Properties
Iron(II) chloride tetrahydrate appears as pale green crystals, soluble in water. Its chemical formula is FeCl₂·4H₂O with a molar mass of about 198.81 g/mol. It is sensitive to air and moisture, easily oxidizing to iron(III) chloride. It has a metallic, slightly acidic taste.
🧪 Applications
This compound is used in water and wastewater treatment, as a precursor in chemical synthesis, and as a reducing agent in laboratories. It is also employed in the textile industry for dyeing and printing.
⚠️ Safety
Iron(II) chloride tetrahydrate should be handled carefully as it can cause irritation to skin, eyes, and respiratory tract. It should be stored in a cool, dry place away from oxidizing agents and moisture to prevent oxidation. Use appropriate protective equipment when handling.
