Copper(II) oxide can be reduced at high temperatures with methane gas in a 'blown' test tube. See ChemPics 'Making a Combustion Tube'.

  • Take a test tube, push in a rubber bung very firmly, heat one point near the end in a roaring Bunsen flame

  • thank you - I am doing this demo for the class tomorrow

  • @DrMoorehen Don't miss the opportunity to turn off the gas and open the tube to expose the hot copper metal to the air when the reduction has hapened. It will go black immediately. Then re-reduce it a second time. Better still, let the kids do it. Regards, Mike. (You will find 'wire form' copper oxide is best, If using powder, use only a tiny amount)
