They get wet. Leave them wet, they get rusty.
If iron nails are left dipped in water in a test tube for a week, they are likely to undergo a chemical reaction called corrosion. Corrosion occurs when iron reacts with oxygen in the presence of water, forming a reddish-brown iron oxide known as rust. Over time, the nails will become covered in rust and may eventually weaken or deteriorate.

The iron piece become covered with a layer of copper.
Unless one or both iron nails are magnetized, then nothing will happen. If one nail is magnetized, then the other nail will be attracted to the magnetized nail.
Very acidic chemicals can melt iron nails.

Nails do not rust in water. Nails only rust in water if oxygen is present. This is because the iron in nails react with oxygen and water to form a compound called hydrated iron(III) oxide.
