Ferrous Sulphate Heptahydrate (FeSO₄·7H₂O)

Ferrous Sulphate Heptahydrate (FeSO₄·7H₂O) is a blue-green crystalline solid used for various industrial, agricultural, and medical applications. It is an iron salt that commonly serves as a source of iron in supplements and in treating iron deficiency in soils and plants. This hydrated form contains seven molecules of water, making it ideal for applications where solubility and easy handling are needed.

Applications:

1. Agriculture:
   • Used as a soil amendment to correct iron deficiency (chlorosis) in plants, particularly in alkaline or calcareous soils.
   • Essential for the production of chlorophyll and overall plant health.
2. Water Treatment:
   • Employed in water purification and sewage treatment as a coagulant, helping to remove impurities and reduce turbidity.
   • Acts as a flocculant to remove suspended particles and phosphates, improving water quality.
3. Industrial Uses:
   • Used in the production of iron-based pigments and dyes, including in the manufacture of inks and textile dyes.
   • Serves as a reducing agent in the treatment of chromate-containing industrial effluents.
4. Health and Medicine:
   • A common ingredient in iron supplements used to treat iron-deficiency anemia.
   • Occasionally used in animal feed to supplement iron intake.
5. Construction:
   • Added to cement or lime mortar to impart color or to act as a hardening agent in construction materials.

Handling and Storage:

• Handling:
  • Use appropriate personal protective equipment (PPE) such as gloves, safety goggles, and protective clothing to avoid skin and eye contact.
  • Avoid inhaling dust; use in a well-ventilated area or with suitable exhaust ventilation.
  • In case of skin or eye contact, wash thoroughly with water.
  • Use caution when handling the chemical to prevent spills or contamination.
• Storage:
  • Store in a cool, dry, and well-ventilated area away from moisture, as the product may lose its hydration and turn into a powdery form when exposed to humidity.
  • Keep the container tightly closed when not in use to prevent moisture absorption.
  • Recommended storage temperature: 10°C to 30°C.
  • Store away from incompatible materials such as strong oxidizers and acids, which may cause decomposition.
  • Properly label and secure storage containers to prevent accidental misuse or spillage.

Ferrous Sulphate Heptahydrate is a versatile compound with applications across agriculture, water treatment, industrial processes, and healthcare. Proper handling and storage are essential to maintaining the quality and effectiveness of the chemical.
