OXIDATION-REDUCTION (REDOX) REACTIONS
1. Oxidation: definition
2. Reduction: definition
3. Redox Reactions
4. Oxidation numbers of central elements in some compounds.
i. Guides students to define oxidation and reduction
ii. Calculate oxidation numbers, using the rules set under objectives (e.g. to calculate oxidation number of central atom in H2SO4, HNO3, KClO3) and hence give their IUPAC names.
