Ferrous chloride tetrahydrate(Cas 13478-10-9) Usage

Definition

ChEBI: A hydrate that is the tetrahydrate form of iron dichloride.

General Description

Iron(II) chloride tetrahydrate is a hydrated metallic halide. Crystal structure studies suggest that it crystallizes in monoclinic system having space group P21/c.

Purification Methods

A 550mL round-bottomed Pyrex flask is connected, via a glass tube fitted with a medium porosity sintered-glass disc, to a similar flask. To 240g of FeCl2.4H2O in the first flask is added conductivity water (200mL), 38% HCl (10mL), and pure electrolytic iron (8-10g). A stream of purified N2 gas is passed through the assembly, escaping through a mercury trap. The salt is dissolved by heating which is continued until complete reduction has occurred. By inverting the apparatus and filtering (under N2 pressure) through the sintered glass disc, unreacted iron is removed. After cooling and crystallisation, the unit is again inverted, and the crystals of ferrous chloride are filtered free from mother liquor by applied N2 pressure. Partial drying by overnight evacuation at room temperature gives a mixed hydrate which, on further evacuation on a water bath at 80o, loses water of hydration and absorbed HCl (with vigorous effervescence) to give a white powder of FeCl2.2H2O (see below).
