4. Nitrogen is unusual in that it can be many forms in the environment, with oxidation states -III, III and V common in water and N₂ or N(0) relatively unreactive with its triple bond. To remove nitrogen pollution (as a nutrient), ammonium (N(-III)) is oxidized to nitrite (N(III)) and then further oxidized to nitrate (N(V)) in a process called nitrification, which is then reduced to N₂ in a process called denitrification. Write balanced redox reactions for the following steps (where you are given both the oxidant and the reductant). a) NH4+ b) NO₂ c) NO3- +++ 0₂ 0₂ CH3OH NO₂ NO3 N₂ 4.
