Ozone is a toxic gas and is a strong oxidising agent even then its present in the stratosphere is very important. Explain what would happen if ozone from this region is completely removed ?

Text Solution

Verified by Experts

Ozone is an important constituent of the stratosphere. Ozone layer acts as a protective blanket or protective shield because it is very effective in absorbing harmful ultra-violet rays given by the sun. Since living cells can be destroyed by ultra-violet radiations, the ozone layer protects us from its damaging effects.

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 :
