Ozone may be a quite chemical element during which every molecule has 3 atoms rather than 2. The formula is O3 . gas is usually created once electricity passes through the air. that's why there's typically associate degree unpleasant smell when a electric storm or around electrical instrumentation .
Ozone may be a blue gas that's explosive and toxic .It is denser than chemical element and condenses into a navy blue liquid at - 112° C. This liquid freezes at – 251° C.
Ozone is employed in several industries. Factories use it for chemical reactions as a result of it reacts a lot of simply than chemical element will. gas conjointly kills germs , that makes it helpful for removing unhealthy smells and sterilizing water. gas is additionally accustomed bleach color out of alternative substances .
