WebMar 22, 2024 · Of the three forms of ultraviolet radiation, ozone completely screens the Earth's surface from UV-C radiation. Portions of UV-B (causes more burning of skin) and … Ozone is a colourless or pale blue gas, slightly soluble in water and much more soluble in inert non-polar solvents such as carbon tetrachloride or fluorocarbons, in which it forms a blue solution. At 161 K (−112 °C; −170 °F), it condenses to form a dark blue liquid. It is dangerous to allow this liquid to warm to its … See more Ozone (or trioxygen) is an inorganic molecule with the chemical formula O 3. It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O … See more In 1785, Dutch chemist Martinus van Marum was conducting experiments involving electrical sparking above water when he noticed an unusual smell, which he attributed to the electrical reactions, failing to realize that he had in fact created ozone. See more Ozone is among the most powerful oxidizing agents known, far stronger than O2. It is also unstable at high concentrations, decaying into ordinary diatomic oxygen. Its See more The standard way to express total ozone levels (the amount of ozone in a given vertical column) in the atmosphere is by using See more The trivial name ozone is the most commonly used and preferred IUPAC name.
