Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O 2 , like liquid oxygen , is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum.
The oxidation state of oxygen is −2 in almost all known compounds of oxygen. The oxidation state −1 is found in a few compounds such as peroxides . Compounds containing oxygen in other oxidation states are very uncommon: − 1 ⁄ 2 ( superoxides ), − 1 ⁄ 3 ( ozonides ), 0 (elemental, hypofluorous acid ), + 1 ⁄ 2 ( dioxygenyl ), +1 ...
The oxidation state of oxygen is −2 in almost all known compounds of oxygen. The oxidation state −1 is found in a few compounds such as peroxides. [125] Compounds containing oxygen in other oxidation states are very uncommon: −1/2 (superoxides), −1/3 , 0 (elemental, hypofluorous acid), +1/2 , +1 (dioxygen difluoride), and +2 (oxygen ...
Oxygen compounds are those chemical compounds which contain the chemical element oxygen. Subcategories. This category has the following 41 subcategories, out of 41 ...
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
Triatomic oxygen (ozone, O 3) is a very reactive allotrope of oxygen that is a pale blue gas at standard temperature and pressure. Liquid and solid O 3 have a deeper blue color than ordinary O 2, and they are unstable and explosive. [5] [6] In its gas phase, ozone is destructive to materials like rubber and fabric and is damaging to lung tissue ...
