    • n ozone a colorless gas (O3) soluble in alkalis and cold water; a strong oxidizing agent; can be produced by electric discharge in oxygen or by the action of ultraviolet radiation on oxygen in the stratosphere (where it acts as a screen for ultraviolet radiation)

  • Interesting fact: On average, there is about three molecules of ozone for every 10 million air molecules.
    • n ozone (Chem) A colorless gaseous substance (O3) obtained (as by the silent discharge of electricity in oxygen) as an allotropic form of oxygen, containing three atoms in the molecule. It is a strong oxidizer, and probably exists in the air, though by the ordinary tests it is liable to be confused with certain other substances, as hydrogen dioxide, or certain oxides of nitrogen. It derives its name from its peculiar odor, which resembles that of weak chlorine.

  • Interesting fact: In 1992, the Antarctic Ozone hole was larger than the continent of North America.
    • n ozone A modification of oxygen, having increased chemical activity; a colorless gas having a peculiar odor like that of air which contains a trace of chlorin. The density of ozone is one and one half times that of oxygen. It is produced when the electric spark is passed through air or oxygen, when a stick of phosphorus is allowed to oxidize slowly, and in various other ways. At a high temperature ozone is changed into ordinary oxygen, two volumes of the former yielding three volumes of the latter. Chemical tests show that ozone exists in the atmosphere to a minute extent, and in greater quantity in country districts than in towns, while in crowded thoroughfares it ceases to be recognizable. Ozone has a great power of destroying offensive odors, and is a powerful bleacher and an intense oxidizer.
    • n ozone In the gaseous state, ozone, if seen through a column of sufficient depth or under considerable pressure, has a blue color like that of ordinary oxygen, but more marked, and when liquefied appears dark blue. The liquid boils under atmospheric pressure at—100° C. (—159° F.). It is magnetic, and more soluble in water than ordinary oxygen. Animals breathing air which contains ozone in appreciable quantity present the phenomena of slow respiration, enfeebled circulation, lowering of bodily temperature, venous condition of the blood, and ultimately death. Air charged with ozone has been applied to the treatment of distilled spirits with a view to the removal of fusel-oil, but with only partial success.
