The rusting process speed up if the iron is in contact with a less reactive metal, such as copper

Rusting occurs more quickly where the iron surface is scratched or bent.

The chemical reaction becomes faster.The rusting process become faster too.

An industrial environment also speeds up the rusting process.This is due to the emission of acidic gases from factories.

First , iron atoms lose electrons to from iron(II)ions.

The electrons then combine with oxygen and water to form hydroxide ions.

The iron(II) ions and hydroxide ions precipitate as iron(II) hydroxide. Iron(II) hydroxide then reacts with dissolved oxygen to form rust ,which is hydrated iron(III) oxide.

The corrosion of iron is called rusting.Rust is the reddish-brown crust that forms on the surface of the iron.
