1 AREP GURME 1 Section 7 Exercise Ozone Experiment (1 of 4) Create ozone in a bottle Materials Oxygen Flask Electrical charge Grounding wire Aluminum foil Rubber band Fruit Results Ozone is a clear gas Rubber band oxidation Gas-to-particle conversion

2 AREP GURME 2 Section 7 Exercise Ozone Experiment (2 of 4) Fill flask with oxygen (O 2 ) Apply electricity to break down oxygen molecules (O 2 ) into atomic oxygen (O), which then combines with existing oxygen molecules to form ozone (O 3 ) Making ozone in a bottle…

3 AREP GURME 3 Section 7 Exercise Ozone Experiment (3 of 4) Flask filled with ozone – approximately 1,000+ ppb! Rubber band cracks due to oxidation by ozone within five minutes Ozone reacting in a bottle…. Insert rubber band into ozone-laden flask

4 AREP GURME 4 Section 7 Exercise Ozone Experiment (4 of 4) Gas (Ozone, VOC) converting to particles… An orange serves as the volatile organic compound (VOC) (terpenes) Inserting a scored orange peel adds VOCs that react with ozone to form particles Ozone gas in the bottle with no particles
