Redox Chemistry
Oxygen/hydrogen, electron-transfer and oxidation-state definitions plus prescribed reagent tests.
The lessons below are in teaching order. Work through them in turn, then come back after practice and use the outcomes on this page to choose what to review. Finishing a topic records participation only. Check your progress to see what you can answer independently and what to review next.
Lessons in order
- 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.
