In 1840, ozone was proposed as a distinct chemical compound by Christian Friedrich Schönbein, who named it after the Greek verb ozein (to smell) from the peculiar odor in lightning storms. Twenty-five years later, in 1865, Jacques-Louis Soret suggested the formula for ozone, O3, which was confirmed by Schönbein in 1867.

Ozone, or O3, is a triatomic molecule and an allotrope of oxygen that is less stable compared to the diatomic O2. Ozone is an extremely reactive gases which is constructed of three oxygen atoms. It is a powerful oxidizing agent, far better than dioxygen. It is very unstable at high concentrations and decays into regular diatomic oxygen. The half-life of ozone in atmospheric conditions is about 30 minutes. This reaction proceeds more rapidly with increasing ...
