ijzerIIInitraat

Ijzer(II)nitraat, also known as ferrous nitrate, has the chemical formula Fe(NO3)2. It is an inorganic compound that typically exists as a hydrated salt, most commonly as the hexahydrate, Fe(NO3)2·6H2O. This salt usually appears as pale green crystals.

Ijzer(II)nitraat is soluble in water and also in ethanol. In aqueous solution, it readily oxidizes in the presence of air to form iron(III) nitrate. This oxidation can be a significant consideration when handling or storing the compound.

The preparation of ijzer(II)nitraat often involves the reaction of iron metal or iron(II) oxide with nitric acid under specific conditions to prevent the immediate oxidation to the iron(III) state. Alternatively, it can be formed by the reduction of iron(III) nitrate.

Ijzer(II)nitraat finds some limited applications. It can be used as a laboratory reagent. Historically, it has been explored for use in photography, particularly in toning processes, and as a mordant in dyeing. Its tendency to oxidize can limit its practical utility in applications where a stable Fe(II) state is required.
