Ozone Benefits And Defects Essay

1052 words - 5 pages

Ozone
According to IUPAC names, ozone is the most commonly name used (ὄζειν) is derived from Greek word which is smell in English and its systematic names 1λ1, 3λ1-trioxidane and μ-oxidodioxygen. In 1840, Christian Friedrich Schönbein who proposed ozone as a distinct chemical substance and in 1867 it confirmed. Ozone is colorless or a little bit bluish gas. In addition, the difference between oxygen and ozone is that oxygen consists of two atoms, but ozone consists of three atoms of oxygen. In other word, when lone oxygen atom react with a breathable oxygen molecule to perform ozone.

In addition, ozone is mostly produced from short-wave ultraviolet rays, but it can be produced from x-rays reacting with O2.

O2 + photon (radiation λ < 240 nm) → 2 O
O + O2 + M → O3 + M
α + β− + O2 → He + O3
Where, (M) is the third body that carries the excess energy from the reaction.



Ozone benefits and defects:-
Ozone occurs in two layers of the atmosphere. The layer closest to the Earth's surface is the troposphere and the other layer is the stratosphere. The ozone layer contains less than ten parts per million of ozone, while the average ozone concentration in Earth's. It is shaped in the stratosphere when ultraviolet light from the sun splits an oxygen molecule into two single oxygen atoms. Each of those oxygen atoms then binds with an oxygen molecule to form an ozone molecule. Ozone layer that can guard everything living on the Earth from harmful ultraviolet rays from the sun. Without Ozone in the atmosphere, it would be very hard for anything to survive on the surface.
Furthermore, Plants cannot live and grow in heavy ultraviolet radiation because ultraviolet rays can also damage sensitive crops, such as soybeans, and reduce crop yields. Some scientists suggest that marine phytoplankton, which are the base of the ocean food chain, are already under stress from ultraviolet ray’s radiation. This stress could have adverse consequences for human food supplies from the oceans. , nor can the plankton that serve as food for most of the ocean life. It’s as a protection to absorb the ultraviolet rays that make the earth become warmer because if it is not, the earth will be hot and that will make arctic north and south will melt and the result is sea will increase and all the living that lives on the ground will sink also ozone layer keep them from doing damage at the Earth's surface. Depletion of stratospheric ozone poses serious health risks for humans and environmental dangers for the planet, and many nations have banned or limited the...

While Chlorine was a very effective sanitiser and oxidiser, and bromine was a strong sanitiser but poor oxidiser, ozone is different again, as it is a very poor sanitiser, but what it lacks in sanitising capabilities it accommodates for in its oxidising ability. Ozone is a chemical compound consisting of
