Ozone Triatomic oxygen, O3, is most commonly known as ozone. It has a resonance structure, and can be drawn in two different ways: O=O- O-O=O It is a bluish, explosive gas at room temperature, and has a boiling point of -119°C. It has a melting point of -193°C, and is a blue liquid. It's critical temperature and pressure are -12.1°C and 53.8 atm, respectively. It has a pleasant odor in concentrations of less than 2 ppm, and is irritating and injurious in
The Ozone Ozone derives from the greek word ozein which means to smell. It was first discovered in 1839 by Christian Friedrick Schonbein who noticed it because of its distinctive acrid smell. He discovered this at the University of Basel in Switzerland. Ozone is merely oxygen, but not the type we breath. Ozone, O3 has three compounds while oxygen has only two. Ozone is reac- tive, meaning it does not stay still, and wants to go back to its original state, with two compounds, O2. This is why ozone
Ozone Ozone (O3) is a molecule consisting of three oxygen atoms, similar to the oxygen we breathe (O2), however oxygen consists of only two oxygen atoms. In the stratosphere, a region high up in the upper atmosphere, light rays are responsible for the breaking down of oxygen (O2), breathable oxygen into its two separate oxygen atoms. Lone oxygen atoms are markedly reactive. When a lone oxygen atom comes into contact with a breathable oxygen molecule (O2) it combines to form ozone (O3). The
Disinfection by Ozone Ozone was discover over 100 years ago in Berlin and it has been use in disinfection of drinking water ever since. Ozone disinfection has been widely used in Europe and US past 10 years. Disinfection is a process that eliminates most pathogenic microorganisms but not include bacterial spores on inanimate objects. Disinfectants are the chemical that use in the disinfection process, where different disinfectants have different target ranges of the microorganism. Disinfection by ozone is one
treat the wastewater is ozone. It is known that ozone is used to treat drinking water but it is quite new in wastewater treatment. Ozone has higher oxidation potential than chlorine thus this allowed ozone to degrade most organic compound. In aqueous solution, ozone able to break aromatic ring. The decomposition of ozone is affected by pH, temperature and ozone concentration. Since ozone is a very reactive molecule, it can react with many organic compounds. The way ozone reacts with the compounds
Ozone Depletion A Case for “Ignoring the Facts” Ozone forms a layer of the earth’s atmosphere that protects us from the sun’s deadly ultraviolet rays. During the last decade there has been a scare set forth by environmental enthusiasts that Chlorofluorocarbons (CFCs) destroy the ozone layer. Although there has been no evidence of any CFC destruction of the ozone layer there is an international stoppage on using CFCs, as well as an executive order set forth by Clinton to limit the sell and use of
Ozone Depletion Atmospheric ozone layer depletion is a serious problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone layer is a region of the stratosphere containing ozone, or O3 gas. The ozone layer is essential to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However, industrial
The Effects of Ozone Pollution The term "ozone" has appeared in numerous magazine and newspaper articles and has been a subject of discussion on both radio and television. Despite all the publicity surrounding this term, however, many people are still confused by it. The confusion arises from the fact that ozone is both beneficial and harmful. We know that the ozone layer in the upper atmosphere acts as a filter for the sun's ultraviolet rays, reducing the amount of radiation that reaches the
Man and the Ozone Ozone is perhaps one of the singularly most important molecules there is. No, not because man came from ozone, but because it forms a protective layer above the earth in it's stratosphere which allowed for the growth of life upon land. Before we had an ozone layer, the rays of the sun struck the earth unimpeded, barraging it with the deadly ultraviolet radiation which prohibited any chance of life on earth. However, there was life in the oceans, plant life in particular. This
without an ozone layer. We have men, we’ve got rickets, we’ve got rockets, we’ve got saran wrap – FIX IT””, said Lewis Black, a comedian. If only it were that easy. However the ozone continues to be depleted because of deforestation. To understand this topic, one must understand what the ozone and deforestation are. The ozone should be protected at any cost. If we fail to protect our ozone, the earth will become one big frozen and lifeless ball. First and foremost, to understand the ozone one must
