A revision video for AQA 7404 A-level Chemistry Inorganic Chemistry 3.2.4 Properties of Period 3 elements and their oxides. This covers:
- A recap of the Year 12 content
- The reactions of sodium and magnesium with water and steam
- The formation of the most common oxides
- The melting points of the oxides
- The reactions when they dissolve in water, including formation of phosphoric, sulfurous and sulfuric acids
- The reactions of the oxides with acids and bases

If you haven't already revised 3.2.1.2 Physical Properties of Period 3 Elements then I would suggest watching that video first!
