Nov 18, 2012  Copper will not displace hydrogen from an acid, due to it's low position in the electrochemical series ECS. However you can use copper with concentrated sulphuric acid to make copper sulphate. This reaction actually occurs in two stages. First the sulphuric acid oxidises the copper to cupric oxide then this reacts to form copper sulphate.
