The lowest oxidation state is −5, as for boron in Al 3 BC [3] and gallium in pentamagnesium digallide (Mg 5 Ga 2). In Stock nomenclature, which is commonly used for inorganic compounds, the oxidation state is represented by a Roman numeral placed after the element name inside parentheses or as a superscript after the element symbol, e.g. Iron ...

It plays a critically important role in the biogeochemical nitrogen cycle as part of the metabolism of ammonia-oxidizing bacteria. The substrate is hydroxylamine ( NH 2 OH {\displaystyle {\ce {NH2OH}}} ), a chemical produced biologically by the enzyme Ammonia monooxygenase .
3 NH 2 OH → N 2 + NH 3 + 3 H 2 O. At least two factories dealing in hydroxylamine have been destroyed since 1999 with loss of life. [35] It is known, however, that ferrous and ferric iron salts accelerate the decomposition of 50% NH 2 OH solutions. [36] Hydroxylamine and its derivatives are more safely handled in the form of salts.
The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts.
Hydroxylammonium chloride is a chemical compound with the formula [NH 3 OH] + Cl −.It is the hydrochloric acid salt of hydroxylamine (NH 2 OH).Hydroxylamine is a biological intermediate in nitrification (biological oxidation of ammonia with oxygen into nitrite) and in anammox (biological oxidation of nitrite and ammonium into dinitrogen gas) which are important in the nitrogen cycle in soil ...
Looking at two slopes among a set of three oxidation states on the diagram, assuming the two standard potentials (slopes) are not equal, the middle oxidation state will either be in a “hill” or in a “valley” shape. A hill is formed when the left slope is steeper than the right, and a valley is formed when the right slope is steeper than ...
The Ponzio reaction (1906) [14] concerning the conversion of m-nitrobenzaldoxime to m-nitrophenyldinitromethane using dinitrogen tetroxide was the result of research into TNT analogues: [15] Ponzio reaction. Gentler oxidants give mono-nitro compounds. [16] In the Neber rearrangement certain oximes are converted to the corresponding alpha-amino ...
