WebZinc oxide is amphoteric, so I'm assuming that zinc is more electronegative than copper and accepts electrons during the reaction. CH3COOH being acidic must be an oxidising agent. Therefore when the current is on, CH3COOH breaks down into two ions, CH3CO+ and OH-, and copper is oxidised, hence explaining the bubbles on copper. Am I right?
