Consider the Voltaic Cell shown below:  The battery consists of a Silver and Nickel electrode connected externally by a wire.  The red arrow shows the direction that electrons will flow when the electrodes are connected.  Answer the following questions… Is the Silver electrode the anode or the cathode? Which electrode will gain mass as the battery operates? What will happen to the as the battery operates? Which electrode would be marked with a (+) symbol?
