| Copper and acid reactions. Close-up of four test tubes each containing copper and acid solutions. From left to right are hydrochloric acid (1 mol concentration),hydrochloric acid (5 mol concentration),nitric acid (1 mol concentration) and nitric acid (5 mol concentration). A reaction is only observed in the strongest concentration of nitric acid. This is an oxidisation reaction producing copper ions,water and nitrogen dioxide gas (bubbles) | |
