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.
3 + 3 NaOH → Fe(OH) 3 + 3 NaNO 3. In fact, when dissolved in water, pure FeCl 3 will hydrolyze to some extent, yielding the oxyhydroxide and making the solution acidic: [12] FeCl 3 + 2 H 2 O ↔ FeOOH + 3 HCl. Therefore, the compound can also be obtained by the decomposition of acidic solutions of iron(III) chloride held near the boiling ...
Fe 2 O 3 + 3 CO → 2 Fe + 3 CO 2. Another redox reaction is the extremely exothermic thermite reaction with aluminium. [17] 2 Al + Fe 2 O 3 → 2 Fe + Al 2 O 3. This process is used to weld thick metals such as rails of train tracks by using a ceramic container to funnel the molten iron in between two sections of rail.
The various crystalline forms of Fe 2 (SO 4) 3 (H 2 O) n are well-defined, often by X-ray crystallography. The nature of the aqueous solutions is often less certain, but aquo-hydroxo complexes such as [Fe(H 2 O) 6] 3+ and [Fe(H 2 O) 5 (OH)] 2+ are often assumed. [4] Regardless, all such solids and solutions feature ferric ions, each with five ...
Ferric oxalate, also known as iron(III) oxalate, refers to inorganic compounds with the formula Fe 2 (C 2 O 4) 3 (H 2 O) x but could also refer to salts of [Fe(C 2 O 4) 3] 3-. Fe 2 (C 2 O 4) 3 (H 2 O) x are coordination polymers with varying degrees of hydration. The coordination complex with the formula [Fe(C 2 O 4) 3] 3-forms a variety of ...
Whereas [Fe(H 2 O) 6] 3+ is nearly colorless, [Fe(SCN)(H 2 O) 5] 2+ is deep red. While iron(III) aquo complexes tend to convert to polymeric oxy-hydroxides, iron(III) complexes with other ligands form stable solutions. The complex with 1,10-phenanthrolinebipyridine is soluble and can sustain reduction to it iron(II) derivative: Redox reaction ...
Iron(II,III) oxide, or black iron oxide, is the chemical compound with formula Fe 3 O 4.It occurs in nature as the mineral magnetite.It is one of a number of iron oxides, the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe 2 O 3) which also occurs naturally as the mineral hematite.
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
