Reaction 1: Elemental copper reacts with aqueous nitric acid to produce copper(II) nitrate, nitrogen dioxide gas, and hydrogen oxide(is this water?).  • Reaction 2: Copper(II)nitrate reacts with sodium hydroxide to form copper(II) hydroxide and sodium nitrate. Copper(II) hydroxide is a blue, gel like solid.  • Reaction 3: Copper(II) hydroxide decomposes upon exposure to heat to yield cupric oxide and water. Cupric oxide is a black solid.  • Reaction 4: Copper(II) oxide reacts with sulfuric acid to produce cupric sulfate and hydrogen oxide. Cupric sulfate is light blue when aqueous.  • Reaction 5: Cupric sulfate reacts with elemental aluminum to create aluminum sulfate and elemental copper. Cupric sulfate dissolves in water to produce a blue solution due to the formation of the hydrated copper(II) cation.
