Iron(II) nitrate is the nitrate of iron that is a green solid and is unstable to heat at room temperature. When heated it is oxidized to Iron(III) nitrate. It is prepared by reacting iron metal with cold dilute nitric acid which results in the green hexahydrate, if it is done below -10 °C it forms the nonahydrate which decomposes back into the hexahydrate when returned to room temperature.
