Ozone Experiment Create ozone in a bottle Materials Oxygen Flask Electrical charge Grounding wire Aluminum foil Rubber band Fruit Ozone is a clear gas Rubber band oxidation Gas-to-particle conversion
1 Results Pollutants Ozone Experiment (2 of 4)
Making ozone in a bottle...
Fill flask with oxygen (O2) Apply electricity to break down oxygen molecules (O2) into atomic oxygen (O), which then combines with existing oxygen molecules to form ozone (O3)
2 Pollutants Ozone Experiment (3 of 4)
Ozone reacting in a bottle.... Flask filled with ozone approximately 1000+ ppb! Insert rubber band into ozone-laden flask Rubber band cracks due to oxidation by ozone within five minutes
3 Pollutants Ozone Experiment (4 of 4)
Gas (Ozone, VOC) converting to particles... An orange serves as the volatile organic compound (terpenes) Ozone gas in the bottle with no particles Inserting a scored orange peel adds VOCs that react with ozone to form particles
