  3. Iron - Wikipedia

    en.wikipedia.org/wiki/Iron

    Thiocyanate is a common test for the presence of iron(III) as it forms the blood-red [Fe(SCN)(H 2 O) 5] 2+. Like manganese(II), most iron(III) complexes are high-spin, the exceptions being those with ligands that are high in the spectrochemical series such as cyanide. An example of a low-spin iron(III) complex is [Fe(CN) 6] 3−.

  4. 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+.

  5. Iron(III) oxide - Wikipedia

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

    Iron(III) oxide is a product of the oxidation of iron. It can be prepared in the laboratory by electrolyzing a solution of sodium bicarbonate, an inert electrolyte, with an iron anode: 4 Fe + 3 O 2 + 2 H 2 O → 4 FeO(OH) The resulting hydrated iron(III) oxide, written here as FeO(OH), dehydrates around 200 °C. [18] [19] 2 FeO(OH) → Fe 2 O 3 ...

  7. Mercury(II) thiocyanate - Wikipedia

    en.wikipedia.org/wiki/Mercury(II)_thiocyanate

    The method involves the addition of mercury thiocyanate to a solution with an unknown concentration of chloride ions and iron as a reagent. The chloride ions cause the mercury thiocyanate salt to dissociate and the thiocyanate ion to bind Fe(III), which absorbs intensely at 450 nm.

  8. Iron(III) nitrate - Wikipedia

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

    Iron(III) nitrate, or ferric nitrate, is the name used for a series of inorganic compounds with the formula Fe(NO 3) 3. (H 2 O) n. Most common is the nonahydrate Fe(NO 3) 3. (H 2 O) 9. The hydrates are all pale colored, water-soluble paramagnetic salts.

  9. Iron(III) fluoride - Wikipedia

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

    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]
