Lawrencite, (Fe,Ni)Cl 2, is the natural counterpart, and a typically (though rarely occurring) meteoritic mineral. [14] The natural form of the dihydrate is rokühnite - a very rare mineral. [ 15 ] Related, but more complex (in particular, basic or hydrated) minerals are hibbingite , droninoite and kuliginite .
Dichlorine monoxide is an inorganic compound with the molecular formula Cl 2 O. It was first synthesised in 1834 by Antoine Jérôme Balard, [2] who along with Gay-Lussac also determined its composition.
Iron(II) chloride tetrahydrate, FeCl 2 ·4H 2 O. In chemistry, iron(II) refers to the element iron in its +2 oxidation state.The adjective ferrous or the prefix ferro-is often used to specify such compounds, as in ferrous chloride for iron(II) chloride (FeCl 2).
Iron (II) hydroxide or ferrous hydroxide is an inorganic compound with the formula Fe(OH) 2. It is produced when iron (II) salts, from a compound such as iron(II) sulfate, are treated with hydroxide ions. Iron(II) hydroxide is a white solid, but even traces of oxygen impart a greenish tinge. The air-oxidised solid is sometimes known as "green ...
Prussian blue or "ferric ferrocyanide", Fe 4 [Fe(CN) 6] 3, is an old and well-known iron-cyanide complex, extensively used as pigment and in several other applications. Its formation can be used as a simple wet chemistry test to distinguish between aqueous solutions of Fe 2+ and Fe 3+ as they react (respectively) with potassium ferricyanide and ...

A single-displacement reaction, also known as single replacement reaction or exchange reaction, is an archaic concept in chemistry.It describes the stoichiometry of some chemical reactions in which one element or ligand is replaced by an atom or group.
A molecular ferric complex is the anion ferrioxalate, [Fe(C 2 O 4) 3] 3−, with three bidentate oxalate ions surrounding the Fe core. Relative to lower oxidation states, ferric is less common in organoiron chemistry , but the ferrocenium cation [Fe(C 2 H 5 ) 2 ] + is well known.
