  2. Iron(III) chloride - Wikipedia

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

    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. [14] Iron(III) chloride also reacts with tetraethylammonium chloride to give the yellow salt of the tetrachloroferrate ...

  3. 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+.

  4. Iron compounds - Wikipedia

    en.wikipedia.org/wiki/Iron_compounds

    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 ...

  7. Potassium ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Potassium_ferrocyanide

    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]

  8. Iron oxide adsorption - Wikipedia

    en.wikipedia.org/wiki/Iron_oxide_adsorption

    The addition of ferric chloride, FeCl 3, to well water immediately after the well at the influent to the treatment plant creates ferric hydroxide, Fe(OH) 3, and hydrochloric acid, HCl. 3H 2 O + FeCl 3 → Fe(OH) 3 + 3HCl. Fe(OH) 3 in water is a strong adsorbent of arsenate, As(V), provided that the pH is low.

  9. Iron(III) citrate - Wikipedia

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

    Ferric citrate or iron(III) citrate describes any of several complexes formed upon binding any of the several conjugate bases derived from citric acid with ferric ions. Most of these complexes are orange or red-brown. They contain two or more Fe(III) centers. [3] Ferric citrates contribute to the metabolism of iron by some organisms. Citrates ...
