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...

Oxalate ion will interfere with the Group D tests after we make the solution acidic. Also, ammonium ion may prevent the precipitation of Group Dcations as hydroxides in sodium hydroxide solution. Thus, must treat the supernatant liquid left after we have precipitated calcium oxalate, in order to destroy any remaining Oxalate or ammonium ions prior to further analysis. To accomplish this, we transfer the solution to a crucible, add concentrated nitric acid and heat the mixture to dryness in a...
