Iron(II) chloride

Iron(II) chloride

0Iron(II) chloride (also known as ferrous chloride) is an inorganic compound with the formula FeCl2. It is a paramagnetic solid with a high melting point, and it is white or light green in color. Iron(II) chloride is one of the most common compounds of iron and is used in many industrial processes.

Chemical Properties

Iron(II) chloride is a weak Lewis acid, reacting with water to form a solution of hydrochloric acid and iron(III) chloride. It is also a reducing agent, capable of reducing manganese dioxide to manganese(II) chloride. When heated, iron(II) chloride decomposes to iron(III) chloride and chlorine gas.

Physical Properties

Iron(II) chloride is a white or light green crystalline solid. It is soluble in water, alcohol, and ether, but insoluble in benzene and carbon disulfide. The compound is paramagnetic, meaning it is attracted to magnetic fields.

Production

Iron(II) chloride is produced by reducing iron(III) chloride with hydrogen in the presence of a catalyst. It can also be produced by the direct reaction of iron with chlorine gas.

Uses

Iron(II) chloride is used in a variety of industrial applications. It is used in the production of ink, in the dyeing of cloth, and in the manufacture of other iron compounds. It is also used as a reducing agent in organic synthesis and in the treatment of sewage and industrial waste.

Safety

Iron(II) chloride is a corrosive substance and can cause burns if it comes into contact with skin or eyes. It is also harmful if swallowed or inhaled.
