Ozone chemistry refers to the study and manipulation of ozone (O3) in various chemical reactions, processes, and systems. Ozone is a highly reactive molecule that can be found in the Earth's stratosphere, where it plays an important role in absorbing ultraviolet radiation from the sun. It also has numerous industrial applications, such as water treatment and air purification. The study of ozone chemistry involves understanding its properties, reactivity, and behavior in different environments, as well as developing methods to create, destroy or control it for various purposes.
