Ozone is an unstable, dark blue diamagne...

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.
Identify the incorrect statement with respect to ozone.

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
(D) Its (i.e.,ozone) advantage over chlorine is that it avoids the unpleasent smell and taste of chlorine.
(C ) True, `O_(2)overset(2500^(circ)C)to2O` , `O+O_(2)overset("quenching")to O_(3)`.
