Chemistry Year 12 - Module 6 - Lesson 4
Neutralisation in Everyday Life & Industry
1. Key Ideas
The chemistry behind treating acid rain, manufacturing fertilisers that feed billions, and neutralising acidic factory waste before it enters waterways is all the same reaction you wrote in L02 — scaled up by orders of magnitude and with real consequences if it goes wrong.
- Balanced equations for all three antacid reactions with HCl
- Why 2 mol NH₃ is needed for H₂SO₄ but only 1 mol for HNO₃ (diprotic vs monoprotic)
2. Success Criteria
By the end, you should be able to:
- Balanced equations for all three antacid reactions with HCl
- The two fertiliser production equations (ammonium sulfate, ammonium nitrate)
- The flue gas desulfurisation equation: Ca(OH)₂ + SO₂ → CaSO₃ + H₂O

5. Short Answer Questions
1. Explain this lesson goal in your own words: "Balanced equations for all three antacid reactions with HCl". Use one specific example from the lesson.
2. Apply this idea to a new example: "The two fertiliser production equations (ammonium sulfate, ammonium nitrate)". Show your reasoning clearly.
3. Analyse why this idea matters for understanding Neutralisation in Everyday Life & Industry: "The flue gas desulfurisation equation: Ca(OH)₂ + SO₂ → CaSO₃ + H₂O".
6. Extend: Apply the Idea
A student gives a memorised answer about Neutralisation in Everyday Life & Industry but does not use evidence or reasoning.
Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.
