ozó
Ozó, commonly known as ozone, is the triatomic allotrope of oxygen with the chemical formula O3. It is a pale blue gas with a sharp odor that can be detected after electrical discharges or lightning. At ordinary temperatures it is unstable and decomposes to diatomic oxygen (O2).
In Earth's atmosphere, Ozó is formed primarily by photochemical reactions: ultraviolet radiation splits O2 into oxygen
Ozone also forms at lower altitudes due to human activity and natural processes. In the troposphere, reactions
Industrial and environmental applications exploit Ozó’s strong oxidizing properties. Ozonation is used to purify drinking water,
Measurement and impact: Ozó concentrations are reported in Dobson Units for the atmospheric column or in parts
