Ozone Reaction with Various Compounds

Many organic and inorganic compounds react with ozone. These reactions can vary greatly depending upon the state of ozone (gaseous or aqueous), and the other chemicals involved in the reaction.

Below is an outline of basic chemical reactions between ozone and certain compounds. This is for reference only, as there are many other variables involved in actual processes. However, this data is helpful as a baseline to understand the fundamentals of ozone reactions and oxidation in general.
