💡 Exam Tips for Neutralisation

🎯 Common Question Types:

  • Write equations for acid + base/hydroxide/carbonate reactions (2-3 marks)
  • Name the salt formed from a given acid and base (1 mark)
  • Explain a real-world neutralisation (antacids, soil treatment) (2-3 marks)
  • Write and explain the ionic equation for neutralisation (HT, 3 marks)
  • Describe observations for acid + carbonate (1-2 marks)

📝 Key Command Words:

  • Write the equation: Balance it and include state symbols if asked
  • Name the salt: Metal from the base + acid ending (-chloride, -sulfate, -nitrate)
  • Explain: Reference H⁺ + OH⁻ → H₂O for any neutralisation explanation
  • Describe observations: What you see, not just the equation

⚠️ Common Mistakes to Avoid:

  • Forgetting to include CO₂ in acid + carbonate equations
  • Using "sulphate" instead of "sulfate" (the correct IUPAC spelling)
  • Balancing H₂SO₄ reactions: remember it provides 2H⁺, so needs 2 hydroxide molecules
  • Confusing H₂ (hydrogen gas, squeaky pop) with CO₂ (carbon dioxide, limewater test)
  • Saying neutralisation always gives pH 7 — only when moles are exactly matched

Practice Questions for Neutralisation Reactions

Which word equation correctly represents a neutralisation reaction?

  • A. acid + metal → salt + hydrogen
  • B. acid + metal carbonate → salt + water + carbon dioxide

Explain why the ionic equation for any strong acid-alkali neutralisation is always H⁺(aq) + OH⁻(aq) → H₂O(l).
