Characteristic
Iron(II) chloride, also known as ferrous chloride, is the chemical compound of formula FeCl2. It is a paramagnetic solid with a high melting point.
Chemical formula：FeCl2•4H2O
Molar mass：198.8102 g/mol
Appearance：Pale green solid
Density：1.93 g/cm3
Melting point：105 °C
Solubility in water：64.4 g/100 mL (10 °C);68.5 g/100 mL (20 °C);105.7 g/100 mL (100 °C)
Solubility in THF：Soluble
log P：−0.15
Magnetic susceptibility (χ)：+14750·10−6 cm3/mol
Crystal structure:Monoclinic
Application
Iron(II) chloride tetrahydrate is used as a reducing agent in metallurgy, in pharmaceutical preparations, as a mordant in dyeing and in sewage treatment. Ferrous chloride has a kind of niche application. During the laboratory synthesis of iron complexes, ferrous chloride acts as a reducing flocculating agent in waste water treatment, particularly for wastes containing chromate. It is the precursor to hydrated iron(III) oxides that are magnetic pigments. Ferrous chloride is employed as a reducing agent in many organic synthesis reactions.
