What is Ozone?
Plain description, key identifiers and synonyms
Ozone is an elemental molecule with formula O3. An explosive, pale blue gas (b.p. 112C) that has a characteristic, pungent odour, it is continuously produced in the upper atmosphere by the action of solar ultraviolet radiation on atmospheric oxygen. It is an antimicrobial agent used in the production of bottled water, as well as in the treatment of meat, poultry and other foodstuffs. It has a role as a mutagen, a tracer, an antiseptic drug, a disinfectant, an electrophilic reagent, an oxidising agent and a member of greenhouse gas. It is a gas molecular entity, an elemental molecule, a member of reactive oxygen species and a triatomic oxygen.

How it is made
In the lab ozone is prepd by passing dry air between two plate electrodes connected to an alternating current source of several thousand volts. The reaction is reversible, & after a little ozone has been produced it is decr at the same rate as it is generated. Obtained in pure form by cooling ozonized air to -180 ยฐc when it separates as a dark blue liq.
Commercial mixt containing up to 2% ozone are produced by electronic irradiation of air. It is usually manufacture on the spot, as it is too expensive to ship. Tonnage quantities are used.
Ozone is prepared by the heating of silver difluoride in a dilute aqueous acid
