  • Nitrogen gas
  • Glass tube
  • Heating mantle
  • Thermometer
  • Safety goggles

Procedure:

1. Put on safety goggles.
2. In a well-ventilated area, set up the glass tube.
3. Add iron filings to the tube and heat them with a Bunsen burner.
4. Pass hydrogen gas and nitrogen gas over the heated iron filings.
5. Monitor the temperature with a thermometer.
6. Gradually increase the temperature until the reaction begins.
7. Observe the formation of ammonia gas as a white cloud.

Key Procedures:
