Lessons in order

  1. Redox Chemistry

    7. Redox Chemistry

Learning goals
  • define oxidation and reduction (redox) in terms of oxygen/hydrogen gain/loss
  • define redox in terms of electron transfer and changes in oxidation state
  • describe the use of aqueous potassium iodide and acidified potassium manganate(VII) in testing for oxidising and reducing agents from the resulting colour changes.
