Iron(III)
chloride, also called ferric chloride, is an industrial scale commodity
chemical compound, with the formula FeCl3. The colour of iron(III) chloride
crystals depends on the viewing angle: by reflected light the crystals appear
dark green, but by transmitted light they appear purple-red. Anhydrous
iron(III) chloride is deliquescent, forming hydrated hydrogen chloride mists in
moist air. It is rarely observed in its natural form, mineral molysite, known
mainly from some fumaroles. When dissolved in water, iron(III) chloride
undergoes hydrolysis and gives off heat in an exothermic reaction. The
resulting brown, acidic, and corrosive solution is used as a flocculant in
sewage treatment and drinking water production, and as an etchant for
copper-based metals in printed circuit boards. Anhydrous iron(III) chloride is
a fairly strong Lewis acid, and it is used as a catalyst in organic synthesis.
Uses
Industrial
In
industrial application, iron(III) chloride is used in sewage treatment and
drinking water production.[13] In this application, FeCl3 in slightly basic
water reacts with the hydroxide ion to form a floc of iron(III) hydroxide, or
more precisely formulated as FeO(OH)−, that can remove suspended materials.
[Fe(H2O)6]3+ + 4 HO− [Fe(H2O)2(HO)4]− + 4 H2O [Fe(H2O)O(HO)2]− + 6 H2O It is also used as a leaching agent in
chloride hydrometallurgy, for example in the production of Si from FeSi.
(Silgrain process) Another important application of iron(III) chloride is
etching copper in two-step redox reaction to copper(I) chloride and then to
copper(II) chloride in the production of printed circuit boards.
FeCl3 + Cu FeCl2 + CuCl FeCl3 + CuCl FeCl2 + CuCl2
Iron(III)
chloride is used as catalyst for the reaction of ethylene with chlorine,
forming ethylene dichloride (1,2-dichloroethane), an important commodity
chemical, which is mainly used for the industrial production of vinyl chloride,
the monomer for making PVC. H2C=CH2 +

Laboratory
use
In
the laboratory iron(III) chloride is commonly employed as a Lewis acid for
catalysing reactions such as chlorination of aromatic compounds and
Friedel-Crafts reaction of aromatics. It is less powerful than aluminium
chloride, but in some cases this mildness leads to higher yields, for example
in the alkylation of benzene: The ferric chloride test is a traditional
colorimetric test for phenols, which uses a 1% iron(III) chloride solution that
has been neutralised with sodium hydroxide until a slight precipitate of FeO(OH)
is formed. The mixture is filtered before use. The organic substance is
dissolved in water, methanol or ethanol, then the neutralised iron(III)
chloride solution is addeda transient or permanent coloration (usually purple,
green or blue) indicates the presence of a phenol or enol. This reaction is
exploited in the Trinder spot test, which is used to indicate the presence of
salicylates, particularly salicylic acid, which contains a phenolic OH group.
Other
uses
Used in anhydrous form as a drying reagent in
certain reactions. Used to detect the presence of phenol compounds in organic
synthesis e.g.: examining purity of synthesised Aspirin. Used in water and
wastewater treatment to precipitate phosphate as iron(III) phosphate. Used by
American coin collectors to identify the dates of Buffalo nickels that are so
badly worn that the date is no longer visible. Used by knife craftsmen and
sword smiths to stain blades, as to give a contrasting effect to the metal, and
to view metal layering or imperfections. Used to etch the widmanstatten pattern in iron
meteorites. Necessary for the etching of photogravure plates for printing
photographic and fine art images in intaglio and for etching rotogravure
cylinders used in the printing industry. Used to make printed circuit boards (PCBs). Used
in veterinary practice to treat overcropping of an animal's claws, particularly
when the overcropping results in bleeding.
Reacts with cyclopentadienylmagnesium bromide
in one preparation of ferrocene, a metal-sandwich complex. Sometimes used in a
technique of Raku ware firing, the iron coloring a pottery piece shades of
pink, brown, and orange. Used to test the pitting and crevice corrosion
resistance of stainless steels and other alloys. Used in conjunction with NaI
in acetonitrile to mildly reduce organic azides to primary amines. Used in an
animal thrombosis model. Iron(III) chloride, also known as ferric chloride, is
a chemical compound. Its chemical formula is FeCl3. It has iron and chloride
ions in it. The iron is in its +3 oxidation state. Iron(III) chloride is a
yellow solid. It dissolves in water to make a colloid of iron(III) oxide,
making the water look muddy. When it is dissolved in an acidic solution, it is
bright yellow. When it is very concentrated in a solution, it is dark brown. It
is corrosive to skin and metals. It reacts with iron to produce iron(II)
chloride. It fumes hydrochloric acid in moist air. It is a weak oxidizing
agent. It reacts with copper(I) chloride to make copper(II) chloride. It breaks
down when heated to make chlorine and iron(II) chloride. It is used in sewage processing. It reacts
with slightly basic water to make a "floc" that can remove things
from the water. It used to react with copper in circuit boards; iron(III)
nitrate is sometimes used too. It is used as a catalyst in making plastics. It
is used in certain tests as a reagent. Ferric chloride is the coagulant of
choice for many industrial and sanitary wastewater treatment applications, due
to its high efficiency, effectiveness in clarification, and utility as a sludge
dewatering agent. The chemical leaves slight residual color, and offers very
good turbidity removal.

Properties
and Applications
Ferric chloride is used in a wide range of
applications including surface water clarification, colour removal, heavy metal
precipitation, industrial effluent treatment and phosphate precipitation in
sewage treatment.
Ferric chloride generally exhibits an optimum pH band and it is important to
determine this for optimum efficiencies.
The inherent pH depression and alkalinity consumption in its coagulation
mechanism generally necessitates a lime dosing facility or similar especially
for low alkalinity waters to achieve the optimum pH range for effective
coagulation. PH correction for stability is invariably required under these
conditions.
In potable water, ferric chloride is used mainly under low turbidity conditions
and while capable of clarifying high turbidity water in combination with lime,
an increasing coagulant aid dosage is recommended as higher turbidity levels
are encountered.
A handling and dosing facility suitable for a corrosive liquid is a
prerequisite for ferric chloride use. Heavy-duty HDPE tanks are recommended for
bulk storage. Compatible fibreglass or rubber lined steel tanks can be used.
FeC should be metered undiluted through a corrosion resistant positive
displacement-dosing pump with subsequent dilution at the dosing point if deemed
necessary for rapid dispersion through the water body. The in-line dilution
should be a minimum 10% solution strength.
