🎯 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
