Electrolysis/Electrochemistry - ------ GCE Study Buddy

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
