Safety

Wear eye protection goggles. Work with poisonous gases only outdoors or in a hood.

Always follow general safety recommendations. Please note that conducting chemistry experiments you must comply with the relevant legal procedures in your country.

Reaction formula

2Fe + 3Cl2 → 2FeCl3

Reagents

  1. Chlorine
  2. Iron wire

Step-by-step instruction

WARNING! This experiment is dangerous! You should NOT perform this at home. ONLY carry out this experiment, if you are a trained chemist, and you understand local safety and legal requirements, which are required to perform such experiments

  1. Obtain chlorine gas. There are many different ways, one of which is shown in the first link.
  2. Collect chlorine gas into a chemical cylinder.
  3. Heat the iron wire (or iron wool) over a gas burner or alcohol lamp.
  4. Quickly add the glowing hot wire into the cylinder with chlorine.
  5. Watch the cylinder fill with yellow-brown smoke.

Scientific background

Chlorine gas is a strong oxidant. Metallic iron is oxidized to ferric chloride, which forms the smoke. The reaction takes place at the interface very slowly, so heating is necessary.
