Question

what conditions are required for rusting to take place​

Answer 1

Answer:

Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur.

Answer 2

The exposure of iron to oxygen in the presence of moisture leads to the formation of rust.
