How Is Ozone Created?

Oxygen molecules are split, by a high-energy electrical discharge, resulting in two individual oxygen atoms and those individual oxygen atoms unite with remaining oxygen molecules to produce a three-atom molecule of ozone. The weak bond holding ozone's third oxygen atom causes the molecule to be extremely unstable and thus, very effective as an oxidizer. An oxidation reaction occurs upon any collision between an ozone molecule and an organic molecule, such as bacteria, viruses, fungus and algae, where the oxygen atom held by the weak bond splits off and only oxygen is left behind.
