Question

Reaction associated with rusting of an iron is it reversible

Answer 1

No it is not reversible

Answer 2

You people are correct. We cannot get back iron from rusted iron by electroplating.It reacts with moist air to form new compounds called rust with molecular formula Fe2O3.nH2o .This oxide layer,rust is not stable and falls off after certain time.Thus rusting of iron is an irreversible change i.e. Rust once formed cannot be converted back into iron.
