How Does Acid Affect Copper Hunker

Jul 17, 2017018332Strong acids include nitric acid, sulfuric acid, hydrochloric acid and phosphoric acid. The ability of an acid to oxidize metals determines its effect on copper. Hydrochloric and phosphoric acid don't oxidize metals well and won't dissolve copper. Sulfuric acid has a medium oxidizing ability and will dissolve copper over time. With a high
