Ozone is an unstable, dark blue diamagnetic gas. It absorbs strongly the UV radiation, thus proteching the people on the earth from the harmful UV radiation from the sun. The use of chloroflurocarbon (CFC) in aeroslos and refrigrators, and their subsequent escape into the atomsphere, is blamond for making holes in the ozone layer over the Antarctic, and Arctic.
Ozone acts as a strong oxdising agent in acidic and alkaline medium. For this property ozone is used as a germicide and disinfectant for sterillising water and improving the atmosphere of croweded places.
CFC damages ozone layer by reactions :

`O_(3)+hv to O+O_(2)`

`CI+O_(3) to CIO+O_(2)`

`CIO+O to CI +O_(2)`

All of these.

Verified by Experts

The correct Answer is:

All reactions are responsible for the depletion of ozone layer.

Ozone is an unstable, dark blue diamagnetic gas. It absorbs strongly the UV radiation, thus proteching the people on the earth from the harmful UV radiation from the sun.

Ozone acts as a strong oxdising agent in acidic and alkaline medium. For this property ozone is used as a germicide and disinfectant for sterillising water and improving the atmosphere of croweded places. which of the following statements is correct ?

The dark blue colour of ozone is due to intense absorption of green light.

oxides of nitrogen and the halogen can not damage the `O_(3)` later.

Ozone oxidises dry iodine to `I_(2)O_(9)`

Ozone forms oragne coloured `KO_(3)` with potassium hydroxide.

Ozone is formed in the upper atmosphere by a photochemical reaction involving dioxygen.

Ozone protects the earth's inhabitants by absorbing UV radiations.

Ozone can also be made by heating `O_(2)` over `2500^(circ)C`. And quenching.

Chloride gas is prefered over zone for the purification of drinking water and for water treatment in swimming pools.
