  • Under "ELECTROCHEMISTRY"
    • Galvanic Cells
      • Standard Reduction Potentials
      • Using Standard Reduction Potentials

Use the Electrolysis simulation to run a virtual electrolysis experiment.

  • Read the Overview and Learning Outcomes, then click on "Experiment".
  • Select the option to run the demonstration.
    • Which metal is the anode? Which is the cathode?
    • Does oxidation or reduction occur at the anode? Which occurs at the cathode?
    • What is the initial mass of the anode? Of the cathode?
    • What are the finam masses of each?
    • Which increased in mass? Which decreased in mass?
    • Which way do the electrons flow?
