INTRODUCTION
Ozone, one of the more active forms of oxygen, is found in the atmosphere in varying
proportions (about 0.05 ppm (0.1 mg/m3) at sea level). It is produced continuously in
the outer layers of the atmosphere by the action of solar ultraviolet radiation on the
oxygen of the air. Ultraviolet lamps commercially sold as “sterilizing lamps” produce
In the laboratory, ozone can be prepared by passing dry air

between two plate electrodes connected to an alternating current source of several
thousand volts. The reaction is reversible, and after a little ozone has been produced, it
is decomposed at the same rate as it is generated (OZ $ Os).
Ozone, a strong oxidizing agent, is used as disinfectant for air and water; for bleaching
waxes, textiles, and oils, and in organic syntheses. It forms ozonides, which are sometimes
useful oxidizing compounds.
