Demonstration of the Industrial Application of Inorganic Chemistry

Experiment: Synthesis of Ferric Chloride

Materials:

  • Iron filings
  • Hydrochloric acid (HCl)
  • Beaker
  • Magnetic stirrer
  • Filter paper
  • Funnel
  • Erlenmeyer flask
  • Hot plate (or other heating source)
  • Safety goggles
  • Gloves

Step-by-Step Procedure:

  1. Put on safety goggles and gloves.
  2. In a beaker, carefully combine iron filings and hydrochloric acid. (Note: This reaction is exothermic and will produce heat. Add the acid slowly to the iron filings to control the reaction.)
  3. Use a magnetic stirrer to stir the mixture vigorously.
  4. Heat the mixture gently on a hot plate until the iron filings dissolve and the solution turns a deep golden-brown color. (Monitor the temperature to avoid excessive boiling.)
  5. Allow the solution to cool slightly before proceeding.
  6. Filter the solution through filter paper into an Erlenmeyer flask to remove any unreacted iron.
  7. Carefully evaporate the filtrate using a hot plate or other suitable method until crystals of ferric chloride form. (This step requires careful control to avoid splattering and decomposition. Consider using a water bath for gentler heating.)

Key Procedures and Safety Considerations:

The use of a magnetic stirrer ensures thorough mixing of the reactants, facilitating the dissolution of iron filings. Careful control of heating during evaporation prevents splattering and decomposition of the product. Always wear appropriate safety equipment, including safety goggles and gloves, when handling chemicals. Hydrochloric acid is corrosive; handle with care and avoid contact with skin and eyes. The reaction is exothermic; take necessary precautions to control the heat generated.

Significance:

Ferric chloride (FeCl3) is an important industrial chemical used in wastewater treatment (coagulation and flocculation), textile dyeing (mordant), etching of circuit boards, and as a catalyst in various chemical processes. This demonstration showcases how inorganic chemistry is applied in industries to produce useful materials.
