Iron 2 to iron 3 oxidation
WebDec 24, 2024 · Ferrous iron is a soluble form of iron that is stable at extremely low pHs or under anaerobic conditions. Under aerobic, moderate pH conditions ferrous iron is oxidized spontaneously to the ferric (Fe 3+) form and is hydrolyzed abiotically to insoluble ferric hydroxide (Fe (OH) 3 ). There are three distinct types of ferrous iron-oxidizing microbes.
