Which electrode will gain mass while a voltaic cell runs and why? (Choose the best answer.) A) The cathode because it undergoes reduction, which means electrons are gained which add mass. B) The cathode because it undergoes reduction, which means that the metallic ions plate onto the cathode. C) The anode because it undergoes reduction, which means that the metallic ions plate onto the anode. D) The anode because it undergoes oxidation, which means that it will lose electrons. E) Neither electrode will gain mass because electrons are lost at the same rate as metallic ions are plated.
