[[File:Liquid ozone.png|thumb|Liquid ozone]]
Ozone is a colourless or pale blue gas, slightly soluble in water, and much more soluble in inert [[non-polar]] solvents such as [[carbon tetrachloride]] or fluorocarbons, in which it forms a blue solution. At {{convert|161|K}}, it condenses to form a dark blue [[liquid]]. It is dangerous to allow this liquid to warm to its boiling point, because both concentrated gaseous ozone and liquid ozone can detonate. At temperatures below {{convert|80|K}}, it forms a violet-black [[solid]].<ref>{{cite web

Ozone has a very specific sharp odour somewhat resembling [[chlorine bleach]]. Most people can detect it at the 0.01&nbsp;μmol/mol level in air. Exposure of 0.1 to 1&nbsp;μmol/mol produces headaches and burning eyes and irritates the respiratory passages.<ref name=brown>{{cite book

Even low concentrations of ozone in air are very destructive to organic materials such as latex, plastics, and animal lung tissue.
