Ozone Definition and 5 Discussions

Ozone (), or trioxygen, is an inorganic molecule with the chemical formula O3. It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O2, breaking down in the lower atmosphere to O2 (dioxygen). Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the Earth's atmosphere. It is present in very low concentrations throughout the latter, with its highest concentration high in the ozone layer of the stratosphere, which absorbs most of the Sun's ultraviolet (UV) radiation.
Ozone's odour is reminiscent of chlorine, and detectable by many people at concentrations of as little as 0.1 ppm in air. Ozone's O3 structure was determined in 1865. The molecule was later proven to have a bent structure and to be weakly paramagnetic. In standard conditions, ozone is a pale blue gas that condenses at cryogenic temperatures to a dark blue liquid and finally a violet-black solid. Ozone's instability with regard to more common dioxygen is such that both concentrated gas and liquid ozone may decompose explosively at elevated temperatures or fast warming to the boiling point.
It is therefore used commercially only in low concentrations.
Ozone is a powerful oxidant (far more so than dioxygen) and has many industrial and consumer applications related to oxidation. This same high oxidizing potential, however, causes ozone to damage mucous and respiratory tissues in animals, and also tissues in plants, and above concentrations of about 0.1 ppm. While this makes ozone a potent respiratory hazard and pollutant near ground level, a higher concentration in the ozone layer (from two to eight ppm) is beneficial, preventing damaging UV light from reaching the Earth's surface.

    Converting mg/hr to ppb

    Editor Note: Moved from a technical forum and therefore no template. Hi! I'm terrible at this sort of thing so came to this forum for help. I'm trying to figure out how much ozone an air purifier will throw into my indoor air. The unit produces 360 mg/hr. My space is 2500 square feet...

    Amateur author seeking help on attacking ozone layer

    Hi, I'm looking for plausible fiction based content regarding environmental destruction. Sort of future UV wars or something. So here goes. Would appreciate any ideas or feedback on what I've come up with so far. Several dissidents build 12ft mirrored parabolic dishes which shine narrow focussed...

    Ozone solubility in water

    Hi everyone Let say i have a 60 liters water tank filled with tap water (no fluoride). And i keep this 60 liters of water saturated with ozone at 600 ORP for 24 hours. The saturation method is just simple airstone zone diffusing method. so, will this ozone gas leaks(or diffuse out) out to the...
