Question

what is the reason iron metals get rusted?​

When iron is in contact with water and oxygen it rusts. If salt is present, for example in seawater or salt spray, the iron tends to rust more quickly, as a result of electrochemical reactions. Iron metal is relatively unaffected by pure water or by dry oxygen.♡
