Iron(II) chloride or ferrous chloride, is a salt of iron with the formula FeCl2.
It exists in nature as the rare mineral Rokühnite (FeCl2·2 H2O).
Ferrous chloride is a white (anhydrous) or green (hydrated) solid, soluble in water.
Iron(II) chloride is sold by chemical suppliers.
Ferrous chloride can be prepared by reacting hydrochloric acid with iron metal. If you want to obtain the solid form, you will have to dry it in the presence of excess iron, in low oxygen environment.
NurdRage has a procedure on making this compound.
- Catalyst in organic chemistry
- Grow beautiful crystals
Ferrous chloride is sensitive to air.
In air-tight containers.
Should be mixed with a base, dried and dumped in trash or strongly diluted and poured down the drain.
