OZONE GAS

Ozone gas is the triatomic form of oxygen, this is it is composed of three oxygen atoms. Ozone's chemical symbol is O3. Under normal conditions ozone is unstable and quickly decomposed to the more stable gaseous oxygen, O2. Because ozone is unstable and cannot be stored successfully, it must be generated at the point of application. Most simply, ozone can be generated by passing oxygen, or air containing oxygen, through an area having an electrical discharge or spark. You may have noticed a clean smell in the air after a thunder and lightning storm. The clean smell was most likely caused by ozone formed by lightning bolts passing through the atmosphere.
