Copper wire (which is high-purity copper) Sulfuric acid (H 2 SO 4 or battery acid) Water; 6-volt Battery; Concentrated sulfuric acid (like the kind in a lab) is 98% sulfuric acid and 2% water, with a concentration of 18.4 M. That is too strong for this project, so you need to dilute it. If you have dilute sulfuric acid, go ahead and use that.

The overall equation for the reaction between copper(II) oxide and dilute sulfuric acid is. CuO(s) + H 2 SO 4 (aq) CuSO 4 (aq) + H 2 O(l) Oxide ions from the copper(II) oxide and hydrogen ions from the acid have combined to make water and aren't there any longer. That leaves the copper(II) ions and the sulfate ions to make the salt copper(II ...
