Fe + 2 HClO 4 + 6 H 2 O → Fe(ClO 4) 2 ·6H 2 O + H 2. Although the ferrous cation is a reductant and the perchlorate anion is a strong oxidant, in the absence of atmospheric oxygen, dissolved ferrous perchlorate is stable in aqueous solution because the electron transfer between both species Fe 2+ and ClO − 4 is hindered by severe kinetic ...
This reaction gives the methanol solvate of the dichloride, which upon heating in a vacuum at about 160 °C converts to anhydrous FeCl 2. [4] The net reaction is shown: Fe + 2 HCl → FeCl 2 + H 2. FeBr 2 and FeI 2 can be prepared analogously. An alternative synthesis of anhydrous ferrous chloride is the reduction of FeCl 3 with chlorobenzene: [5]
Fe 0 + 2 H + → Fe 2+ + H 2. Iron(II) is oxidized by hydrogen peroxide to iron(III), forming a hydroxyl radical and a hydroxide ion in the process. This is the Fenton reaction. Iron(III) is then reduced back to iron(II) by another molecule of hydrogen peroxide, forming a hydroperoxyl radical and a proton.
Ammonium chloride is an inorganic chemical compound with the chemical formula N H 4 Cl, also written as [NH 4]Cl.It is an ammonium salt of hydrogen chloride.It consists of ammonium cations [NH 4] + and chloride anions Cl −.
The sulfate salt [Fe(bipy) 3]SO 4 is produced by combining ferrous sulfate with excess bipy in aqueous solution. This result illustrates the preference of Fe(II) for bipyridine vs water. Addition of cyanide to this solution precipitates solid Fe(bipy) 2 (CN) 2. [2]
A molecular ferric complex is the anion ferrioxalate, [Fe(C 2 O 4) 3] 3−, with three bidentate oxalate ions surrounding the Fe core. Relative to lower oxidation states, ferric is less common in organoiron chemistry , but the ferrocenium cation [Fe(C 2 H 5 ) 2 ] + is well known.
Cp 2 TiCl 2 + 2 PR 3 + Mg → Cp 2 Ti(PR 3) 2 + MgCl 2. Alkyne derivatives of titanocene have the formula (C 5 H 5) 2 Ti(C 2 R 2) and the corresponding benzyne complexes are known. [24] One family of derivatives are the titanocyclopentadienes. [25] Rosenthal's reagent, Cp 2 Ti(η 2-Me 3 SiC≡CSiMe 3), can be prepared by this method.
FeC 2 O 4 → FeO + CO 2 + CO. The procedure is conducted under an inert atmosphere to avoid the formation of iron(III) oxide (Fe 2 O 3). A similar procedure can also be used for the synthesis of manganous oxide and stannous oxide. [6] [7] Stoichiometric FeO can be prepared by heating Fe 0.95 O with metallic iron at 770 °C and 36 kbar.
