    2021-6-24 · Explanation: Zinc is more reactive than copper.Thus, it is more electropositive than copper, meaning that zinc loses electrons more easily than copper. As a result, oxidation occurs at the zinc rod (the anode) and zinc metal loses electrons to become zinc ions, that is, Zn (s) 2e---> Zn 2+ (aq) The electrons then flow from the zinc rod to the copper rod through the external circuit.,
