When the solution is diluted with water, water molecules displace the nitrate ions in the coordinate sites around the copper ions, causing the solution to change to a blue color. In dilute nitric acid, the reaction produces nitric oxide, NO, instead: 3Cu(s) + 8HNO3(aq) > 3Cu(NO3)2(aq) + 2NO(g) + 4H2O(l) In the following demonstration, a balled-up piece of thin copper wire is added to about 100 mL of concentrated nitric acid; once the copper is added the evolution of nitrogen dioxide occurs quickly.
