WebAug 21, 2024 · Iron is very easily oxidized under alkaline conditions. Oxygen in the air oxidizes the iron (II) hydroxide precipitate to iron (III) hydroxide especially around the top of the tube. The darkening of the precipitate comes from the same effect. In the iron (III) case: Reactions of Iron Ions with Ammonia Ammonia can act as both a base and a ligand. Under anaerobic conditions, the iron(II) hydroxide can be oxidised by the protons of water to form magnetite (iron(II,III) oxide) and molecular hydrogen. This process is described by the Schikorr reaction: 3 Fe(OH)2 → Fe3O4 + H2 + 2 H2O Anions such as selenite and selenate can be easily adsorbed on the positively charged surface of i…
