Ferric nitrate nonahydrate (CAS NO.7782-61-8) also can be called for Iron(+3)nitrate enneahydrate ; Iron(III) nitrate ; Iron(III) nitrate-9-hydrate ; Iron(III) nitrate enneahydrate ; Iron(III) nitrate,hydrous ; Iron(III) nitrate nonahydrate ; Iron(III) nitrate,nonohydrate . Ferric nitrate nonahydrate (CAS NO.7782-61-8) is a strong oxidizer and it may lead to fire when contact with combustible material. It's incompatible with combustible material, strong reducing agents, most common metals, organic material. Ferric nitrate nonahydrate is a pale purple solid and it's stable under normal shipping and handling conditions. However, it may decompose if heated. May discolor on exposure to light. After decomposition, Ferric nitrate nonahydrate turned into nitrogen oxides , irritating and toxic fumes and gases.When heated to decomposition it emits toxic fumes of NOx.
