Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green.
Your right hcl won't dissolve copper without an oxidizer to change the copper to copper oxide. Hcl can dissolve copper oxide. The only thing you need is an oxidizer. That can come from the oxygen in the water or oxygen that is adsorbed from the air into solution.We can also use an air bubbler or H2O2. Anything hcl and oxygen is basically what we call AP or acid peroxide that eats copper.cl can dissolve copper oxide. The only thing you need is an oxidizer. That can come from the oxygen in the water or oxygen that is adsorbed from the air into solution. We can also use an air bubbler or H2O2.
