Section 7 Exercise

Ozone Experiment (2 of 4)

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)

Making ozone in a bottle…

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

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 particlesOzone gas in the bottle with

no particles
