This reaction is called oxidation. Oxidation occurs when electrons are exchanged between molecules, which changes their molecular structure. The most familiar type of oxidation occurs when iron is exposed to air. The presence of oxygen has changed the chemical structure of the iron. Ozone has the same oxidizing effect but oxidizes many more substances at a faster rate.
Ozone is one of nature's strongest oxidizers.
Because of ozone's air-freshening effect by oxidation of odors, ozone generators are now used to freshen the air in offices and industrial facilities. Many of these generators use a process called corona discharge to produce the ozone. Corona discharge occurs by producing controlled sparks in the presence of oxygen. Ozonation is a process of injecting ozone into the air. The ozone reacts with the odor to produce odorless gases.
