    After washing, loaded organic phase was stripped using sulfuric acid solution with concentration of 200 g/L. When O/A was 1:1, after two countercurrent stripping, the copper stripping rate was 98.13%.How Does Acid Affect Copper? Hunker,Strong 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.
