Elementary iron dissolves in water under normal conditions. Many iron compounds share this characteristic. Naturally occurring iron oxide, iron hydroxide, iron carbide and iron penta carbonyl are water insoluble. The water solubility of some iron compounds increases at lower pH values.
Other iron compounds may be more water soluble than the examples mentioned above. Iron carbonate has a water solubility of 60 mg/L, iron sulphide of 6 mg/L, and iron vitriol even of 295 g/L. Many iron chelation complexes are water soluble.
Usually there is a difference between water soluble Fe2+ compounds and generally water insoluble Fe3+ compounds. The latter are only water soluble in strongly acidic solutions, but water solubility increases when these are reduced to Fe2+ under certain conditions.
