Compare and contrast an electrolytic cell with a voltaic cell. Provide one example where both are present in daily life.

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.
