To perform the dehydration reaction, the solution containing was heated under bunsen burner. This heat breaks down the molecular bonds of to usually from Another dissolution reaction was performed in order to convert Cu into aqueous state by adding 3M sulfuric acid. The two H+ in sulfuric acid reacts with the O in CuO to form This solution was filtered by a vacuum to remove the sulfur. The filtrate contained Cu in an aqueous form and was transfer into a new beaker. Lastly, Zinc was added to the new beaker to reduced Cu (aq) to Cu (s). This is oxidation and reduction reaction because . This copper was recovered through vacuum filtration. After performing these reactions to recover copper, the % yield of copper. Throughout the experiment, some of the Copper was lost due to poor lab techniques. During the dehydration reaction, the copper solution was bubbling. A stir rod was left in the beaker to prevent the bubbling.
