WebJan 14, 2007 · When coins are left in your pocket for a long time, the copper in them reacts with the oxygen in the air and turns into copper oxide. That's the black gunky stuff on the outside of the coin. When you put that in an acid it will dissolve the copper oxide leaving behind just the shiny metal coin. WebFirst, copper is oxidized to copper oxide with heat, then it transfers this oxygen to acetone returning to its metallic form. In the next reaction with acetone, the copper surface becomes bright because of the transfer of the oxygen and begins to glow red hot because of the energy that’s released from the reaction. Why is the copper wire glowing?
