It reacts with organics to oxidize unpleasant odors and kill germs. 3 or enriched oxygen containing 3 atoms instead of 2. 2. Give an example. Inside the body, food molecules combine with O 2 to form CO 2 and H 2 O and energy or heat. Oxidation means a substance undergoes a chemical change resulting in a different substance.
Fire is an example of oxidation.
Ozone was discovered in 1840 by a German chemist. It has been used for many years to purify water in Europe. Industrial applications include odor control, sterilization, and many others. Ozone is produced commercially by an electrical process in which a pair of electrodes is separated by air when the electrical potential builds up from a generator. The electron velocity generates an excitation in which oxygen molecules dissociate and form O 3 or ozone.
