Iron would be displaced by aluminium.


I'm actually not sure if a green precipitate would be formed, but iron would definitely be displaced by aluminium.

First, re-look the reactivity series for metals, and you would find that aluminium is further up the series than iron. Hence, it is more reactive than iron, and hence would displace iron from its nitrate.
