  2. Iron(III) nitrate - Wikipedia

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

    Iron(III) nitrate is a useful precursor to other iron compounds because the nitrate is easily removed or decomposed. It is for example, a standard precursor to potassium ferrate K 2 FeO 4. [6] When dissolved, iron(III) nitrate forms yellow solutions.

  3. Iron(II) nitrate - Wikipedia

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

    The solution of the iron(II) nitrate-hydrazine complex is produced by the reaction of hydrazine nitrate and ferric nitrate at 40 °C with copper(II) nitrate as a catalyst: [8] 4 Fe(NO 3) 3 + N 2 H 5 NO 3 → 4 Fe(NO 3) 2 + N 2 + 4 HNO 3. If the compound is used in situ, the compound is produced by the reaction of iron(II) chloride and calcium ...

    en.wikipedia.org/wiki/Iron_nitrate

    Iron nitrate may refer to: Iron(II) nitrate , Fe(NO 3 ) 2 , a green compound that is unstable to heat Iron(III) nitrate (or ferric nitrate), Fe(NO 3 ) 3 , a pale violet compound that has a low melting point

  5. Iron nitrides - Wikipedia

    en.wikipedia.org/wiki/Iron_nitrides

    Iron has five nitrides observed at ambient conditions, Fe 2 N, Fe 3 N 4, Fe 4 N, Fe 7 N 3 and Fe 16 N 2.They are crystalline, metallic solids. Group 7 and group 8 transition metals form nitrides that decompose at relatively low temperatures—iron nitride, Fe 2 N decomposes with loss of molecular nitrogen at around 400 °C and formation of lower-nitrogen content iron nitrides.

  6. Potassium ferrate - Wikipedia

    en.wikipedia.org/wiki/Potassium_ferrate

    In 1702, Georg Ernst Stahl (1660 – 1734) observed that the ignition product of potassium nitrate (saltpetre) and iron powder displayed a red-purple color in an aqueous solution, which was eventually attributed to hexavalent potassium ferrate. Eckenberg and Becquerel in 1834 reported that a red-purple color appeared during heating of a mixture ...

  8. Iron (III) oxide-hydroxide - Wikipedia

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

    Iron(III) oxide-hydroxide or ferric oxyhydroxide [2] is the chemical compound of iron, oxygen, and hydrogen with formula FeO(OH). The compound is often encountered as one of its hydrates, FeO(OH) ·n H 2 O [rust]. The monohydrate FeO(OH) · H 2 O is often referred to as iron(III) hydroxide Fe(OH) 3, [3] hydrated iron oxide, yellow iron oxide ...

  9. Potassium ferrioxalate - Wikipedia

    en.wikipedia.org/wiki/Potassium_ferrioxalate

    The anion is a transition metal oxalate complex consisting of an iron atom in the +3 oxidation state and three bidentate oxalate C 2 O 2− 4 ligands. Potassium is a counterion, balancing the −3 charge of the complex. In solution, the salt dissociates to give the ferrioxalate anion, [Fe(C 2 O 4) 3] 3−, which appears
