Molecular Weight 399.88 g/mol

Ferric sulfate (Fe2(SO4)3) is an inorganic salt, also known as iron(III) sulfate, and is commonly used as a coagulant in water treatment and as a hemostatic agent in dentistry. It appears as a grayish-white powder or yellow crystals and is soluble in water. In water treatment, it helps remove suspended particles, while in dentistry, it aids in controlling bleeding during procedures. It is also used in aluminum etching, soil conditioning, and as a dye fixative. 

Industrial Uses

1. Water Treatment

  • Coagulation and Flocculation: Ferric sulfate is added to water during the coagulation process, where it neutralizes the negative charges of suspended particles like clay, silt, and organic matter. This neutralization allows the particles to come closer together and form larger, heavier aggregates called flocs. The flocs are then separated from the water through sedimentation (settling to the bottom) or filtration. 
  • Phosphate Removal: Phosphates in wastewater can lead to excessive algal growth in natural water bodies (eutrophication). Ferric sulfate reacts with phosphates to form insoluble iron phosphates, which can be easily removed from the water.

2. Construction

  • Chromate Reduction in Cement: Ferric sulfate is used to reduce hexavalent chromium (chromium VI) in cement to the less toxic trivalent chromium (chromium III). Chromium VI is a potential environmental hazard, and reducing it to chromium III is an important step in making cement more sustainable.

3. Performance Chemicals

  • Synthesis of Thiourea: Ferric sulfate has been used as an oxidizing agent in a high-yield synthesis of thiourea, offering a more efficient alternative to methods like hydrogen peroxide oxidation.
  • Catalysis: Ferric sulfate can act as a heterogeneous catalyst in organic reactions like the Povarov reaction, which is used to synthesize pyrano- and furanotetrahydroquinolines.

4. Metal Treatment

  • Scale and Rust Removal: In the steel industry, ferric sulfate (often in the form of a solution) is used to remove rust and scale from metal surfaces (a process called pickling). This process prepares the metal for further treatment or coating.
  • Corrosion Prevention: By removing the oxide layer, ferric sulfate can help prevent further corrosion of the metal.
