FeCl 3 + 3 CH 3 CH 2 ONa → "Fe(OCH 2 CH 3) 3" + 3 NaCl Iron(III) chloride forms a 1:2 adduct with Lewis bases such as triphenylphosphine oxide ; e.g., FeCl 3 (OP(C 6 H 5 ) 3 ) 2 . The related 1:2 complex FeCl 3 (OEt 2 ) 2 , where Et = C 2 H 5 ) , has been crystallized from ether solution.
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+. The word ferric is derived from the Latin word ferrum, meaning "iron". Although often abbreviated as Fe 3+, that naked ion does not exist
Iron(II) chloride (ferrous chloride, iron dichloride), FeCl 2; Iron(III) chloride (ferric chloride, iron trichloride), FeCl 3 This page was last edited on 15 May 2022 ...
The sample is dissolved in water, or a mixture of water and ethanol, and a few drops of neutral ferric chloride (FeCl 3) solution, which is prepared by adding de-ionised water. Add sodium hydroxide to the mixture until a permanent brown precipitate is formed.
Tetrachloroferrate is the polyatomic ion having chemical formula FeCl − 4. The metallate can be formed when ferric chloride (FeCl 3) abstracts a chloride ion from various other chloride salts. [1] The resulting tetrachloroferrate salts are typically soluble in non-polar solvents.
The iron compounds produced on the largest scale in industry are iron(II) sulfate (FeSO 4 ·7H 2 O) and iron(III) chloride (FeCl 3). The former is one of the most readily available sources of iron(II), but is less stable to aerial oxidation than Mohr's salt ((NH 4) 2 Fe(SO 4) 2 ·6H 2 O). Iron(II) compounds tend to be oxidized to iron(III ...

An alternative synthesis of anhydrous ferrous chloride is the reduction of FeCl 3 with chlorobenzene: [5] 2 FeCl 3 + C 6 H 5 Cl → 2 FeCl 2 + C 6 H 4 Cl 2 + HCl. For the preparation of ferrocene ferrous chloride is generated in situ by comproportionation of FeCl 3 with iron powder in tetrahydrofuran (THF). [6]
