is a very active form of oxygen. It is formed
when oxygen is exposed to a high-energy
field causing some oxygen molecules (O2)
to break down to oxygen atoms (O). The oxygen
atoms (O) then react with the oxygen molecules
(O2) to form ozone (O3). Notice that this
is a reversible reaction meaning that ozone
can decompose back to oxygen.
ozone found in nature?
ozone is formed by lightening. In nature,
ozone is produced by the action of lightning
on the oxygen found in the air. The formation
of ozone leads to the fresh smell that you
find outside after a lightning storm. One
type of ozone generator, known as the corona
discharge type, mimics this natural process
in its ozone generating cells.
ozone is found in the Earth's stratosphere.
Also, the ozone layer found in the upper
stratosphere protects the earth's surface
from harmful UV rays. UV rays cleave oxygen
molecules into oxygen atoms which recombine
to form ozone. UV rays also excite ozone
molecules causing them to breakdown to oxygen
to begin the cycle again. In this way, the
energy of the UV rays is absorbed by the
"ozone layer" protecting the Earth's surface
from their harmful effects. UV-type ozone
generators mimic this natural process.
can ozone be used for?
very reactive nature of ozone makes it the
ideal oxidant for air and water treatment.
