I always get confused about this. If you don't have a chart of whats a stronger reducing agent, and they dont tell u which side is oxidation and which is reduction, how do you tell which is the anode and/or cathode? Like.. unless u memorize, how do u know if in the zinc copper redox equation, its the zinc or the copper thats being reduced?

activity series of metals, zinc will replace copper in solution without any electricity.
