    Why iron can be used to get copper from copper sulfate ...

    Basically what happens is the more reactive metal bonds to the non-metal bit of the original compound and this causes the less reactive metal to be pushed out. A really important implication of this is using scrap iron to displace copper from a solution. This only works because iron is more reactive than copper.
