Ozone

Physical Characteristics:

  • a.k.a. Triatomic oxygen

  • Formula - O3

  • M.W. = 48.00

  • bluish gas; pleasant characteristic odor at concentrations less than 2 ppm; irritating and injurious at higher concentrations (dark blue as liquid below -180 degr. C)

  • Powerful oxidizing agent; unstable, explosive when warmed

  • Density = 2.144 g/liter

  • Melting point = -193 degr. C; Boiling point = -111.9 degr. C

  • Earth air conc. - 0.05 ppm; produced in outer layers of the atmosphere by the action of ultraviolet light on oxygen in the air.
