  2. Iron(II) chloride - Wikipedia

    en.wikipedia.org/wiki/Iron(II)_chloride

    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.

  4. Iron(III) chloride - Wikipedia

    en.wikipedia.org/wiki/Iron(III)_chloride

    2 FeCl 3 + Fe → 3 FeCl 2. A traditional synthesis of anhydrous ferrous chloride is the reduction of FeCl 3 with chlorobenzene: [25] 2 FeCl 3 + C 6 H 5 Cl → 2 FeCl 2 + C 6 H 4 Cl 2 + HCl. iron(III) chloride releases chlorine gas when heated above 160 °C, generating ferrous chloride: [16] 2FeCl 3 → 2FeCl 2 + Cl 2

    Fe + 2 HX → FeX 2 + H 2 (X = F, Cl, Br, I) Iron reacts with fluorine, chlorine, and bromine to give the corresponding ferric halides, ferric chloride being the most common. [13] 2 Fe + 3 X 22 FeX 3 (X = F, Cl, Br) Ferric iodide is an exception, being thermodynamically unstable due to the oxidizing power of Fe 3+ and the high reducing ...

  6. Iron(II) hydroxide - Wikipedia

    en.wikipedia.org/wiki/Iron(II)_hydroxide

    Fe(OH) 2 adopts the brucite structure, i.e. the arrangement of the atoms in the crystal are the same as the arrangement of the atoms in Mg(OH) 2. The Fe(II) centers are bonded to six hydroxide ligands. Each hydroxide ligand bridges to three Fe(II) sites. The O-H bonds are perpendicular to the planes defined by the oxygen atoms, projecting above ...

  7. Radium chloride - Wikipedia

    en.wikipedia.org/wiki/Radium_chloride

    Gaseous RaCl 2 shows strong absorptions in the visible spectrum at 676.3 nm and 649.8 nm (red): the dissociation energy of the radium–chlorine bond is estimated as 2.9 eV, [6] and its length as 292 pm. [7] Contrary to diamagnetic barium chloride, radium chloride is weakly paramagnetic with a magnetic susceptibility of 1.05 × 10 6. Its flame ...

  8. Ferric - Wikipedia

    en.wikipedia.org/wiki/Ferric

    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+.
