Study Notes
Cleaning Magnesium Ribbon
- Magnesium is a highly reactive metal that reacts with oxygen to form a layer of magnesium oxide (MgO) on its surface.
- The magnesium oxide layer is stable and prevents further reaction of magnesium with oxygen.
- To remove the magnesium oxide layer, the magnesium ribbon is cleaned with sandpaper, allowing the underlying metal to react.
Balanced Chemical Equations
- Hydrogen reacts with chlorine to form hydrogen chloride: H₂ + Cl₂ → 2HCl
- Barium chloride reacts with aluminium sulphate to form barium sulphate and aluminium chloride: 3BaCl₂ + Al₂(SO₄)₃ → 2AlCl₃ + 3BaSO₄
- Sodium reacts with water to form sodium hydroxide and hydrogen: 2Na + 2H₂O → 2NaOH + H₂
Learn about the importance of cleaning a magnesium ribbon before burning in air and the formation of magnesium oxide. Understand the reactivity of magnesium and its interaction with oxygen.
