Oxides
7.2What the syllabus asks of you
- Describe amphoteric oxides as oxides that react with acids and bases to produce a salt and water
- Classify oxides as acidic, including SO2 and CO2, basic, including CuO and CaO, or amphoteric, limited to Al2O3 and ZnO, related to metallic and non-metallic character
