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.
Use 20% aqueous solution of ferric chloride, it is necessary to immerse the objects in solution, dry and wax or varnish. [32] Gray-black for zinc. Use 20% aqueous solution of ferric chloride, the objects are immersed for 20 minutes, after the appearance of colour, objects should be washed, dried and waxed or varnished. [32] Black for aluminum
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".

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.
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]
In the wet oxidation method, K 2 FeO 4 is prepared by oxidizing an alkaline solution of an iron(III) salt. Generally, this method employs either ferrous (Fe II) or ferric (Fe III) salts as the source of iron ions, calcium, sodium hypochlorite (Ca(ClO) 2, NaClO), sodium thiosulfate (Na 2 S 2 O 3) or chlorine (Cl 2) as oxidizing agents and, finally, sodium hydroxide, sodium carbonate (NaOH, NaCO ...
