Iron(II) chloride, also known as ferrous chloride, is the chemical compound of formula FeCl 2.It is a paramagnetic solid with a high melting point. The compound is white, but typical samples are often off-white.
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). The adjective ferric is used instead for iron(III) salts, containing the cation Fe 3+.

In terms of its being an oxidant, iron(III) chloride oxidizes iron powder to form iron(II) chloride via a comproportionation reaction: [10] 2 FeCl 3 + Fe → 3 FeCl 2. A traditional synthesis of anhydrous ferrous chloride is the reduction of FeCl 3 with chlorobenzene: [25] 2 FeCl 3 + C 6 H 5 Cl → 2 FeCl 2 + C 6 H 4 Cl 2 + HCl
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 ...
Iron chloride may refer to: Iron(II) chloride (ferrous chloride, iron dichloride), FeCl 2; Iron(III) chloride (ferric chloride, iron trichloride), FeCl 3
Nickel(II) fluoride NiF 2 is yellow, crystallising in the rutile structure and can form a trihydrate, NiF 2 ·3H 2 O. [3] A tetrahydrate also exists. [4] Nickel chloride NiCl 2 is yellow, crystallising in the cadmium chloride structure. It can form a hexahydrate, NiCl 2 ·6H 2 O, a tetrahydrate NiCl 2 ·4H 2 O over 29 °C and a dihydrate, NiCl ...
