Questions and Answers

In an electrochemical cell, what is the role of the anode?

  • Undergoes oxidation (loss of electrons) (correct)
  • Produces electrical energy
  • Is positive
  • Undergoes reduction (gain of electrons)

    • Which type of cell spontaneously undergoes oxidation-reduction reactions to produce electrical energy?

  • Galvanic cell (correct)
  • Electrolytic cell
  • Absorption spectroscopy cell
  • Conformational isomer

    • What is the formula to calculate the cell potential (Ecell) in an electrochemical cell?

  • Ecell = Eanode - Ecathode
  • Ecell = Eanode / Ecathode
  • Ecell = Eanode + Ecathode (correct)
  • Ecell = Ecathode - Eanode
