1. Use both the diagram and activity series below to fill in the missing answers in the table below. Use these answers provided as clues in adding the missing information. Then answer the questions that follow. • Most active (most easily Li K oxidized; Ba Sr loses electrons Ca most easily) Na Mg Al Mn Zn Fe Cd Co Ni Sn Pb H Cu 5 Ag Hg Least active Au = 1 Metal copper strip 6 Solution = cadmium nitrate 2 Solution = copper (II) nitrate 7 3 Cathode or Anode? 8 Metal = cadmium 4 9 5 Cathode or Anode? Refer to the activity series above. Which metal should be the anode and the cathode? Explain your answer. • Describe in detail how the electrons will flow through the device. • Provide a detailed explanation for how this wet voltaic cell works. Your explanation must include the actual oxidation and reduction half-reactions that are occurring in this cell.
