Front of white light occurs on paper
name: Demonstration of the chemiluminescence of white phosphorous
Elementary Productions: Gas phase chemiluminescence with P4
Pyrophoric yellow phosphorus
by MN's LAB
Wear lab goggles and gloves. White phosphorus is very toxic and chemically active! Avoid contact of white phosphorous with skin.
Always follow general safety
recommendations. Please note that conducting chemistry
experiments you must comply with the relevant legal procedures in
- Take a piece of paper.
- Dissolve some white phosphorous in gasoline in a test-tube.
- Pour some solution onto the paper. After a few seconds a white glow occurs.
White phosphorous is a very reactive substance. It slowly oxidizes in contact with air and emits white light. This phenomenon is called chemiluminescence.
When the solution of white phosphorous in gasoline is placed on paper, gasoline evaporates and white phosphorous reacts with oxygen from air.
