Definition - What does Ozone mean?
Ozone is a pale blue gas with a distinctive pungent smell and a sharp odor. It is an inorganic molecule with the chemical formula O3. The gas is a reminiscent of chlorine and is detectable at concentration as small as 10ppb in air. It is an allotrope of oxygen, which is less stable than diatomic allotrope with the chemical formula O2. The gas breaks down in lower atmospheres to the normal dioxygen. It is formed from dioxygen by electrical discharges in the atmosphere, activities of ultraviolet light and it is present throughout the earth's atmosphere in low concentrations.
Petropedia explains Ozone
Ozone is used in various consumer and industrial applications corresponding to oxidation as it is a powerful oxidant. The high potential of oxidation makes Ozone damage the respiratory tissues and mucous in the animals and tissues of plants with high concentration of about 100ppb. This potential makes it a pollutant and respiratory hazard near the ground level. It can be both bad and good in accordance to its location in the atmosphere as the Ozone layer present in stratosphere is useful for preventing damage or harm to plants and animals from ultraviolet rays which reach the surface of the Earth. It can be commercially used in disinfecting, deodorizing and bleaching. It is also commonly known as trioxygen and iriatomic oxygen.
