Electrochemistry is important in many aspects of daily life.

1. Define voltaic cell.
2. Fill in the blanks for the drawing of a voltaic cell that’s made with copper/copper (II) nitrate (E° = 0.34 V) and zinc/zinc (II) nitrate (E° = –0.76 V). Briefly explain the role of the salt bridge.

• Using the equation E°cell = E°cathode – E°anode, calculate the overall cell potential for the cell in step b. Be sure to show all steps completed to arrive at the answer.
