Electrochemistry: Voltaic Cells

Experiment #20 from Advanced Chemistry with Vernier

In this experiment, you will

  • Prepare a Cu-Pb voltaic cell and measure its potential.
  • Test two voltaic cells that use unknown metal electrodes and identify the metals.
  • Prepare a copper concentration cell and measure its potential.
  • Prepare a lead concentration cell and measure its potential.
  • Use the Nernst equation to calculate the Ksp of PbI2.
