CHAPTER 7: Redox Reactions and Electrolysis

CHAPTER 7: Redox Reactions and Electrolysis

  • Oxidation and Reduction
  • Electrolysis

Learning outcomes:

    • calculate oxidation numbers of elements in compounds and ions
    • describe and explain redox processes in terms of electron transfer and/or changes in oxidation number (oxidation state).
    • use changes in oxidation numbers to help balance chemical equations
  • explain, including the electrode reactions, the industrial processes of:
  • the electrolysis of brine, using a diaphragm cell
  • the extraction of aluminium from molten aluminium oxide/cryolite.
  • the electrolytic purification of copper
