Many iron chelation complexes are water soluble. Usually there is a difference between water soluble Fe 2+ compounds and generally water insoluble Fe 3+ compounds. The latter are only water soluble in strongly acidic solutions, but water solubility increases when these are reduced to Fe 2+ under certain conditions.
