Edexcel IAL Chemistry A2 16.1 oxidation and reduction
Track the element that changes oxidation number, then state whether electrons are gained or lost and use that change to justify the redox decision.
How this is tested
- Use oxidation-number changes to justify whether a reaction is redox or not.
- Link reduction to electron gain and a decrease in oxidation number in MCQ contexts.
- Identify which species is oxidised or reduced from balanced equations or half-cells.
