  2. Nitrate - Wikipedia

    en.wikipedia.org/wiki/Nitrate

    In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.

  3. NOx - Wikipedia

    en.wikipedia.org/wiki/NOx

    NO y is the class of compounds comprising NO x and the NO z compounds produced from the oxidation of NO x which include nitric acid, nitrous acid (HONO), dinitrogen pentoxide (N 2 O 5), peroxyacetyl nitrate (PAN), alkyl nitrates (RONO 2), peroxyalkyl nitrates (ROONO 2), the nitrate radical (NO 3), and peroxynitric acid (HNO 4).

  4. Nitrification - Wikipedia

    en.wikipedia.org/wiki/Nitrification

    Nitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite. Nitrification is an important step in the nitrogen cycle in soil . The process of complete nitrification may occur through separate organisms [ 1 ] or entirely within one organism, as in comammox bacteria.

  5. Nitrogen compounds - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_compounds

    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.

  6. Nitrogen oxide - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_oxide

    Name Formula Nitroxide: O=N − or NO −: Nitrite: O=N−O − or NO − 2: Nitrate: O 2 N−O − or NO − 3: Peroxynitrite: O=N−O−O − or NO − 3 ...

  7. Nitrogen - Wikipedia

    en.wikipedia.org/wiki/Nitrogen

    Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk-delivered ...

  8. Praseodymium compounds - Wikipedia

    en.wikipedia.org/wiki/Praseodymium_compounds

    Praseodymium can form many different oxides, although the only oxides that are stable at room temperature are Pr 2 O 3, Pr 6 O 11 and PrO 2.Praseodymium(III) oxide is a green powder that forms hexagonal crystals, [14] and crystallizes in the manganese(III) oxide or bixbyite structure. [15]

  9. Nitrite - Wikipedia

    en.wikipedia.org/wiki/Nitrite

    The formal oxidation state of the nitrogen atom in nitrite is +3. This means that it can be either oxidized to oxidation states +4 and +5, or reduced to oxidation states as low as −3. Standard reduction potentials for reactions directly involving nitrous acid are shown in the table below: [4]
