ferrous chloride

Ferrous chloride is employed as a reducing agent in many organic synthesis reactions.

For example, ferric chloride can be prepared thus, but ferrous chloride cannot.

Ferric chloride decomposes to ferrous chloride at high temperatures.

For example, sodium cyclopentadienide reacts with ferrous chloride to yield ferrocene:

Iron(II) chloride, also known as ferrous chloride, is a chemical compound.

Hydrated forms of ferrous chloride are generated by treatment of wastes from steel production with hydrochloric acid.

Alternatively, the addition of ferrous chloride FeCl to the digestion tanks inhibits hydrogen sulfide production.

Under the Stock system FeCl was called iron(II) chloride rather than ferrous chloride.

Ferrous chloride is conveniently prepared by addition of iron powder to a solution of methanol and concentrated hydrochloric acid under an inert atmosphere.

Ferrous chloride (iron(II) chloride)

Ferrous chloride has a variety of niche applications, but the related compounds ferrous sulfate and ferric chloride enjoy more applications.

Some low-oxidation state transition metals have halides which dissolve well in water, such as ferrous chloride, nickelous chloride, and cupric chloride.

Aside from use in the laboratory synthesis of iron complexes, ferrous chloride serves as a reducing flocculating agent in wastewater treatment, especially for wastes containing chromate.

In its original form, the chemical garden involved the introduction of ferrous chloride (FeCl) crystals into a solution of potassium silicate (KSiO, water glass).

By 1974, the composition of Venus' clouds had not yet been determined, with many scientists proposing a wide variety of compounds, including liquid water and aqueous solutions of ferrous chloride.

The spent acid has long been re-used as iron(II) chloride (also known as ferrous chloride) solutions, but high heavy-metal levels in the pickling liquor have decreased this practice.

Sodium ferrocyanide is produced industrially from hydrogen cyanide, ferrous chloride, and calcium hydroxide, the combination of which affords Ca[Fe(CN)]11HO.

CHNO + 3 H CHNH + 2 HO Originally, the reduction was effected with a mixture of ferrous chloride and iron metal via the Bechamp reduction.

Although many plants operate acid recovery plants, (particularly those using Hydrochloric acid), where the mineral acid is boiled away from the iron salts, there remains a large volume of highly acid ferrous sulfate or ferrous chloride to be disposed of.
