What is process ozone?
Ozone is naturally produced in the stratosphere by a two- step reactive process. In the first step, solar ultraviolet radiation (sunlight) breaks apart an oxygen molecule to form two separate oxygen atoms. In the over- all process, three oxygen molecules plus sunlight react to form two ozone molecules.
How is ozone prepared?
We can prepare ozone by passing a silent electric discharge through dry, unadulterated, and cold oxygen in an extraordinary device. This device is what we know as the ozoniser. In this process, we obtain the gas of up to 10% concentration. That is why we use a silent electric discharge.
What are the 6 steps of ozone depletion?
The stratospheric ozone depletion process begins with the emission of halogen source gases by human activities and natural processes. Those emitted by human activities are also called ozone-depleting substances (ODSs). Subsequent steps are accumulation, transport, conversion, chemical reaction, and removal.
Which method is used for preparing ozone from oxygen?
Preparation of ozone Ozone is prepared in laboratory by passing silent electric discharge through dry oxygen. By passing the electric current some of the oxygen molecules dissociate and then atomic oxygen combines with oxygen molecules to form ozone.
How will you prepare ozone by laboratory method?
Ozone is prepared in the laboratory by passing silent electric discharge through dry oxygen. Silent electric discharge is given in order to produce less heat as ozone is prone to decompose back into oxygen with increase in temperature.
What are the 3 steps of ozone depletion?
Emission, accumulation, and transport. The principal steps in stratospheric ozone depletion caused by human activities are shown in Figure Q6-1.
What is a ozone depletion?
Ozone Depletion. When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. Ozone can be destroyed more quickly than it is naturally created.
