Dissolution of Copper Metal Copper reacts readily with strong oxidizing agents (substances that readily remove electrons from other suhstances-i.e... Cu- Cu2 +2e). In this experiment, aqueous nitric acid, HNO, oxidizes copper metal to the copper(II) ion (opening photo): Cu(s) +4 HNO,(aq)Cu(NO)(aq) +2 NO (8) +2 H,0( .Cu HNO3 Cu(NO3)2 (28.1) CuSO The products of this reaction are copper(II) nitrate, Cu(NO)2 (a water-soluble salt that produces a blue solution), and nitrogen dioxide, NO2 (a dense, toxic, red-brown gas). The solution remains...
