After this lesson, you should be able to:

  • Give the standard conditions for standard electrode potentials to be determined
  • Describe the standard hydrogen electrode and explain its role as the reference electrode
  • Explain how standard electrode potentials can be determined based on the reference electrode
  • Calculate the emf of a standard galvanic cell using the Table of Standard Reduction Potentials
  • Understand a positive emf as indicating that the reaction is spontaneous
