Aside from lability, which applies to anhydrous and hydrated forms, the reactivity of anhydrous ferric chloride reveals two trends: It is a Lewis acid and an oxidizing agent. [20] Reactions of anhydrous iron(III) chloride reflect its description as both oxophilic and a hard Lewis acid. Myriad manifestations of the oxophiliicty of iron(III ...
Iron(II) chloride, also known as ferrous chloride, is the chemical compound of formula FeCl 2. It is a paramagnetic solid with a high melting point. The compound is white, but typical samples are often off-white.
Potassium ferrioxalate contains the iron(III) complex [Fe(C 2 O 4) 3] 3−. In chemistry, iron(III) or ferric refers to the element iron in its +3 oxidation state. Ferric chloride is an alternative name for iron(III) chloride (FeCl 3). The adjective ferrous is used instead for iron(II) salts, containing the cation Fe 2+.
Some low-oxidation state transition metals have halides which dissolve well in water, such as ferrous chloride, nickelous chloride, and cupric chloride. Metal cations with a high oxidation state tend to undergo hydrolysis instead, e.g. ferric chloride, aluminium chloride, and titanium tetrachloride. [1]
A famous reaction involves treatment with ferric salts, most commonly Iron(III) chloride, to give Prussian blue. In the reaction with Iron(III) chloride, producing Potassium chloride as a side-product: 3 K 4 [Fe(CN) 6] + 4 FeCl 3 → Fe 4 [Fe(CN) 6] 3 + 12 KCl With the composition Fe III 4 [Fe II 6]
Iron(III) fluoride, also known as ferric fluoride, are inorganic compounds with the formula FeF 3 (H 2 O) x where x = 0 or 3. They are mainly of interest by researchers, unlike the related iron(III) chloride. Anhydrous iron(III) fluoride is white, whereas the hydrated forms are light pink. [2]
Another similar route is the decomposition of iron(III) nitrate dissolved in stearic acid at about 120 °C. [15] The oxyhydroxide prepared from ferric chloride is usually the β polymorph (akaganeite), often in the form of thin needles. [14] [16] The oxyhydroxide can also be produced by a solid-state transformation from iron(II) chloride ...
In organic chemistry, Keller's reagent is a mixture of anhydrous (glacial) acetic acid, concentrated sulfuric acid, and small amounts of ferric chloride, used to detect alkaloids. Keller's reagent can also be used to detect other kinds of alkaloids via reactions in which it produces products with a wide range of colors.
