A clearer look at how iron reacts in the environment

Sep 06, 2012 Because iron(II) is more soluble than iron(III), when an electron hops to an iron atom at the mineral surface, that iron(II) atom can be released into solution, and dramatically affect the chemistry and mineralogy of soils and surface waters. Iron reduction is particularly important for the mobility of contaminants in the environment.
