Copper extraction - Wikipedia

Actually, the nitrate ion oxidizes the copper metal to copper (II) ion while itself being transformed to NO 2 gas in the process; the copper (II) ion then binds to six water molecules. The physical change you should observe is the copper-colored metal vanishing as the solution turns blue (from [Cu(H 2 O) 6 ] 2+, the hexaaquacopper ion) and a brown gas (NO 2 ) is evolved.
