Experiment: Synthesis of Iron(III) Chloride Hexahydrate Using Green Chemistry Principles

Materials:



  • Iron filings
  • Hydrochloric acid (HCl)
  • Hydrogen peroxide (H2O2)
  • Water
  • Beaker
  • Magnetic stirrer

Procedure:



  1. In a beaker, dissolve 10 g of iron filings in 50 mL of 6 M HCl.
  2. Add 10 mL of 30% H2O2 to the solution.
  3. Stir the solution vigorously using a magnetic stirrer for 30 minutes.
  4. Filter the solution and wash the precipitate with water.
  5. Dry the precipitate in an oven at 100°C.

Key Procedures:



  • Use of hydrogen peroxide as an oxidant: Hydrogen peroxide is a green alternative to traditional inorganic oxidants such as potassium permanganate or dichromate, which can generate toxic byproducts.
  • Avoiding the use of organic solvents: The synthesis is performed in aqueous solutions, eliminating the need for harmful organic solvents.
  • Minimizing waste production: The reaction produces minimal waste, as the only byproduct is water.

Significance:



  • Educational: This experiment demonstrates the principles of green chemistry, such as using less toxic materials and minimizing waste.
