Choose AS2.7 Redox from the menu
- A very good site giving an analysis of a simple redox reaction.
- Oxidation states - Note that hydrides are not included in the Level 2 course.
- Writing redox equations - Note that balancing in alkaline/basic conditions is NOT required in Level 2.
- Oxidation and reduction as electron transfer - Note: ignore loss and gain of O and H and scroll down to “Oxidation and reduction in terms of electron transfer”.
