Iron(III) nitrate, or ferric nitrate, is most commonly encountered as the nonahydrate Fe(NO₃)3·9H₂O. In this state it forms colourless to pale violet crystals, typical of non-hydrolysed iron(III) compounds. It is deliquescent and rapidly forms a pool of water if left in air. Therefore it is usually stored in tightly closed containers to keep it away from any trace of water or water vapour. Heating of its solution results in hydrolysis, and heating the solid hydrate decomposes it to a mixture of iron and nitrogen oxides.
