  Iron - LoveToKnow 1911
Ferrous fluoride, FeF 21 is obtained as colourless prisms (with 8H 2 O) by dissolving iron in hydrofluoric acid, or as anhydrous colourless rhombic prisms by heating iron or ferric chloride in dry hydrofluoric acid gas.
Ferrous bromide, FeBr 2, is obtained as yellowish crystals by the union of bromine and iron at a dull red-heat, or as bluish-green rhombic tables of the composition FeBr 2.6H 2 O by crystallizing a solution of iron in hydrobromic acid.
Ferrous sulphate, green vitriol or copperas, FeSO 4.7H 2 O, was known to, and used by, the alchemists; it is mentioned in the writings of Agricola, and its preparation from iron and sulphuric acid occurs in the Tractatus chymico-philosophicus ascribed to Basil Valentine.

 Metal Conservation
When iron is buried in an aerobic soil or exposed on the surface to the air, the ferrous ions initially formed in the corrosion process oxidize to ferric ions, resulting in layers of ferric oxide scale on the metal surface.
The secondary stage, the oxidation of the ferrous ion compounds to a ferric state, is modified in anaerobic environments.
The hydrogen sulfide reacts with the ferrous ion from the anodic areas to produce ferrous sulfide and ferrous hydroxide, two major corrosion compounds of iron associated with objects recovered from the sea (Leigh 1973:205).
