Iron(II) perchlorate is the inorganic compound with the formula Vorlage:Chem2. A green, water-soluble solid, it is produced by the reaction of iron metal with dilute perchloric acid followed by evaporation of the solution:[3]
In solution, iron(II) perchlorate slowly oxidizes in air to iron(III) oxyhydroxide.[4]
The hexahydrate consists of discreet hexaaquoiron(II) dications and perchlorate anions. It crystallizes with an orthorhombic structure.[2] It has minor phase transitions at 245 and 336 K.[5]
Uses
[Bearbeiten | Quelltext bearbeiten]In organic chemistry, iron(II) perchlorate can be used as a source of ferrous ions for the Fenton oxidation.[1]
