CAPE CHEMISTRY UNIT 1 MODULE 3

KINETICS & EQUILIBRIA

OBJECTIVES

• Define the terms standard electrode (redox) potential and standard cell potential.
• Describe the standard hydrogen electrode.
• Describe methods used to measure the standard electrode potentials:
  • metals or non - metals in contact with their ions in aqueous solutions
  • ions of the same element in different oxidation states.
• Calculate standard cell potentials from standard electrode potentials of two half cells.
• Use standard electrode potentials of cells:
  • to determine the direction of electron flow.
  • to determine the feasibility of a reaction.
• Predict how the value of an electrode potential varies with concentration.
• Apply the principles of redox processes to energy storage devices.
