Ph of ozone
Ozone in the ozone layer filters out sunlight wavelengths from about 200 nm UV rays to 315 nm, with ozone peak absorption at about 250 nm. This ozone UV absorption is important to life, since it extends the absorption of UV by ordinary oxygen and nitrogen in air (which absorb all wavelengths < 200 nm) through … 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 According to experimental evidence from microwave spectroscopy, ozone is a bent molecule, with C2v symmetry (similar to the water molecule). … See more Ozone is a bent triatomic molecule with three vibrational modes: the symmetric stretch (1103.157 cm ), bend (701.42 cm ) and antisymmetric stretch (1042.096 cm ). The symmetric … See more The trivial name ozone is the most commonly used and preferred IUPAC name. The systematic names 2λ -trioxidiene and catena-trioxygen, valid IUPAC names, are constructed … See more 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 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 half-life varies with atmospheric conditions such as temperature, … See more WebSep 16, 2024 · Ozone can be “good” or “bad” for health and the environment depending on where it’s found in the atmosphere. Stratospheric ozone is “good” because it protects …

The prediction of ozone solubility is more complicated than for other gasses, because ozone solubility is influenced by several factors, such as temperature, pH and dissolved matter. This is a consequence of the instability of ozone in water.
