Iron(II) sulfate outside a titanium dioxide factory in Kaanaa, Pori, Finland. Upon dissolving in water, ferrous sulfates form the metal aquo complex [Fe(H 2 O) 6] 2+, which is an almost colorless, paramagnetic ion. On heating, iron(II) sulfate first loses its water of crystallization and the original green crystals are converted into a white ...
Ferric sulfate, Iron(III) sulfate, Fe 2 (SO 4) 3 Index of chemical compounds with the same name This set index article lists chemical compounds articles associated with the same name.
Iron sulfates occur as a variety of rare (commercially unimportant) minerals. Mikasaite, a mixed iron-aluminium sulfate of chemical formula (Fe 3+, Al 3+) 2 (SO 4) 3 [6] is the name of mineralogical form of iron(III) sulfate. This anhydrous form occurs very rarely and is connected with coal fires.

The iron compounds produced on the largest scale in industry are iron(II) sulfate (FeSO 4 ·7H 2 O) and iron(III) chloride (FeCl 3). The former is one of the most readily available sources of iron(II), but is less stable to aerial oxidation than Mohr's salt ((NH 4) 2 Fe(SO 4) 2 ·6H 2 O). Iron(II) compounds tend to be oxidized to iron(III ...
Siderotil is an iron(II) sulfate hydrate mineral with formula: FeSO 4 ·5H 2 O which forms by the dehydration of melanterite. [2] Copper commonly occurs substituting for iron in the structure. It typically occurs as fibrous or powdery encrustations, but may also occur as acicular triclinic crystals. [3]

Szomolnokite (Fe 2+ SO 4 ·H 2 O) is a monoclinic iron sulfate mineral forming a complete solid solution with magnesium end-member kieserite (MgSO 4 ·H 2 O). [2] In 1877 szomolnokite's name was derived by Joseph Krenner from its type locality of oxidized sulfide ore containing iron in Szomolnok, Slovakia (Hungary at the time).
