Iron Nitrate
Iron nitrate may refer to: * Iron(II) nitrate, Fe(NO3)2, a green compound that is unstable to heat * Iron(III) nitrate Iron(III) nitrate, or ferric nitrate, is the name used for a series of inorganic compounds with the formula Fe(NO3)3.(H2O)n. Most common is the nonahydrate Fe(NO3)3.(H2O)9. The hydrates are all pale colored, water-soluble paramagnetic salts. Hy ...

Iron(II) Nitrate
Iron(II) nitrate is the nitrate salt of iron(II). It is commonly encountered as the green hexahydrate, Fe(NO3)2·6H2O, which is a metal aquo complex, however it is not commercially available unlike iron(III) nitrate due to its instability to air. The salt is soluble in water serves as a ready source of ferrous ions. Structure No structure of any salt Fe(NO3)2·xH2O has been determined by X-ray crystallography. Nonetheless, the nature of the aquo complex e(H2O)6sup>2+ is well known and relatively insensitive to the anion. The Fe-O distances are longer for e(H2O)6sup>2+ (2.13 Å) than for the ferric analogue e(H2O)6sup>3+ (1.99 Å). Both e(H2O)6sup>n+ complexes are high spin, which results in pale colors, paramagnetism, and weak Fe-O bonds. Production Iron(II) nitrate can be produced in multiple ways such as the reaction of iron metal with cold dilute nitric acid: :3Fe + 8HNO3 + 12H2O → 3Fe(NO3)2(H2O)6 + 2NO If this reaction is conducted below -10 °C, nonahyd ...
