Dilute solutions of ferric chloride produce soluble nanoparticles with molecular weight of 10 4, which exhibit the property of "aging", i.e., the structure change or evolve over the course of days. [13] The polymeric species formed by the hydrolysis of ferric chlorides are key to the use of ferric chloride for water treatment.
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+. The word ferric is derived from the Latin word ferrum, meaning "iron".
Illustrative of its powerful oxidizing properties, ammonium persulfate is used to etch copper on printed circuit boards as an alternative to ferric chloride solution. [1] [6] This property was discovered many years ago. In 1908, John William Turrentine used a dilute ammonium persulfate solution to etch copper.
Hemin is protoporphyrin IX containing a ferric iron (Fe 3+) ion with a coordinating chloride ligand. Chemically, hemin differs from the related heme-compound hematin chiefly in that the coordinating ion is a chloride ion in hemin, whereas the coordinating ion is a hydroxide ion in hematin. [ 2 ]
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]
Iron(II) chloride tetrahydrate, FeCl 2 ·4H 2 O. In chemistry, iron(II) refers to the element iron in its +2 oxidation state. The adjective ferrous or the prefix ferro-is often used to specify such compounds, as in ferrous chloride for iron(II) chloride (FeCl 2). The adjective ferric is used instead for iron(III) salts, containing the cation Fe 3+.
Iron(II) chloride, also known as ferrous chloride, is the chemical compound of formula FeCl 2. It is a paramagnetic solid with a high melting point. The compound is white, but typical samples are often off-white.
FeOCl is prepared by heating iron(III) oxide with ferric chloride at 370 °C (698 °F) over the course of several days: [2] Fe 2 O 3 + FeCl 3 → 3 FeOCl. Alternatively, FeOCl may be prepared by the thermal decomposition of FeCl 3 ⋅6H 2 O at 220 °C (428 °F) over the course of one hour: [3] FeCl 3 ⋅ 6H 2 O → FeOCl + 5 H 2 O + 2 HCl
