What is iron chloride used for?

The primary use of ferric chloride is to remove impurities in water and for wastewater treatment. Ferric chloride is also one of the few water treatment chemicals that can sequester odors.

What is the iron chloride?

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. The compound is white, but typical samples are often off-white.

Is ferric chloride the same as iron chloride?

Ferric Chloride, also know as Iron(III) chloride, and Iron chloride, is an industrial scale commodity chemical compound. When dissolved in water, the compound undergoes hydrolysis resulting in a brown highly corrosive, acidic solution that is used as a flocculent in sewage treatment and drinking water production.

Why ferric chloride test is used?

The ferric chloride test is used to determine the presence of phenols in a given sample or compound (for instance natural phenols in a plant extract). Enols, hydroxamic acids, oximes, and sulfinic acids give positive results as well.

What are the uses of iron ( III ) chloride ( FeCl3 )?

Anhydrous iron (III) chloride is a fairly strong Lewis acid, and it is used as a catalyst in organic synthesis. The brownish-yellow hexahydrate is a common commercial form of ferric chloride, a yellowish species described by the formula [FeCl2 (H2O)4]Cl.2H2O (compare chromium (III) chloride).

How is ferrous chloride used in the laboratory?

Aside from use in the laboratory synthesis of iron complexes, ferrous chloride serves as a coagulation and flocculation agent in wastewater treatment, especially for wastes containing chromate or sulfides. It is the precursor to hydrated iron (III) oxides that are magnetic pigments. FeCl 2 finds some use as a reagent in organic synthesis.

How is ferric chloride used in water treatment?

In another industrial application, ferric chloride is an alternative to iron (III) sulfate in water treatment, where FeCl 3 is treated with hydroxide ion to form a floc of “iron (III) hydroxide” (more correctly formulated as FeO (OH)) that can remove suspended materials.

Why is anhydrous iron III chloride used as an etchant?

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.
