Ozone is a form of elemental oxygen. The molecules of ozone contain three oxygen atoms (O3) and are unstable with respect to O2. It is a very reactive gas.Ozone is diamagnetic, which means that its electrons are all paired.Ozone can be formed when a mixture of O2 and NO2 is exposed to bright light.The largest use of ozone is in the preparation of pharmaceuticals, synthetic lubricants, and many other commercially useful organic compounds, where it is used to sever carbon-carbon bonds.It can also be used for bleaching substances and for killing microorganisms in air and water sources.Ozone is a reagent in many organic reactions in the laboratory and in industry.Ozone can be used to detoxify cyanide wastes by oxidizing cyanide to cyanate and eventually to carbon dioxide.Ozone is used in homes and hot tubs to kill bacteria in the water and to reduce the amount of chlorine or bromine.Ozone is also widely used in treatment of water in aquariums and fish ponds. Its use can minimize bacterial growth, control parasites, eliminate transmission of some diseases, and reduce or eliminate yellowing of the water.
