  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. 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.

  4. 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]

  6. Sodium nitrite - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitrite

    Industrial production of sodium nitrite follows one of two processes, the reduction of nitrate salts, or the oxidation of lower nitrogen oxides. One method uses molten sodium nitrate as the salt, and lead which is oxidized, while a more modern method uses scrap iron filings to reduce the nitrate. [4] [84] NaNO 3 + Pb → NaNO 2 + PbO

  7. Nitrification - Wikipedia

    en.wikipedia.org/wiki/Nitrification

    Nitrogen cycle. 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.

  8. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    Systematic oxidation state is chosen from close alternatives as a pedagogical description. An example is the oxidation state of phosphorus in H 3 PO 3 (structurally diprotic HPO(OH) 2) taken nominally as +3, while Allen electronegativities of phosphorus and hydrogen suggest +5 by a narrow margin that makes the two alternatives almost equivalent:

  9. Nitrifying bacteria - Wikipedia

    en.wikipedia.org/wiki/Nitrifying_bacteria

    [12] [13] Complete nitrification, the conversion of ammonia to nitrate in a single step known as comammox, has an energy yield (∆G°′) of −349 kJ mol −1 NH 3, while the energy yields for the ammonia-oxidation and nitrite-oxidation steps of the observed two-step reaction are −275 kJ mol −1 NH 3, and −74 kJ mol −1 NO 2 − ...
