They get wet. Leave them wet, they get rusty.
If iron nails are dipped in water in a test tube for a week, they are likely to undergo a chemical reaction known as rusting, where they react with oxygen and water to form iron oxide. This process weakens the iron nails and causes them to corrode and become covered with a reddish-brown layer.

You can use a magnet to separate the iron nails from the starch. The iron nails will be attracted to the magnet and can be easily picked up. The starch can then be dissolved in water and filtered to remove any remaining debris.
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.

rust, lots of rust.
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.
Tap water contains dissolved oxygen and other minerals that can accelerate the rusting process of iron nails. When iron is exposed to water and oxygen, a chemical reaction occurs called corrosion, leading to the formation of iron oxide (rust) on the surface of the nails.
Oxidization
iron nails are nails made up of iron
When iron is dipped in zinc sulfate, a layer of zinc is deposited on the surface of the iron. This process is known as galvanization. The color of the iron changes to a shiny silver color due to the deposition of the zinc layer.

Rusting of iron needs the presence of water.
Iron nails exposed to vinegar for 2 days will undergo a chemical reaction called oxidation, resulting in the formation of iron oxide (rust) on the surface of the nails. This reaction occurs due to the acidity of the vinegar, which speeds up the oxidation process of the iron.
No, a magnet does not lose its power of attraction when it is dipped in water. The magnetic field of the magnet remains intact in water and it can still attract objects.
