Chemistry Year 12 - Module 6 - Lesson 16
Titration Curves — Interpreting & Analysing All Four Types
1. Key Ideas
A pharmaceutical chemist reads a titration curve for a new drug candidate and extracts four pieces of information in under a minute — the drug's pK a , its concentration, whether it is a weak acid or base, and which indicator to use for quality control. Every feature of the curve is quantitative data, not decoration.
- The shape and key features of all four titration curve types
- Why strong/strong has the largest pH jump (no buffer capacity)
2. Success Criteria
By the end, you should be able to:
- The shape and key features of all four titration curve types
- That pKa is read from the half-equivalence point (V_EP/2)
- Which regions correspond to which calculation method

5. Short Answer Questions
1. Explain this lesson goal in your own words: "The shape and key features of all four titration curve types". Use one specific example from the lesson.
2. Apply this idea to a new example: "That pKa is read from the half-equivalence point (V_EP/2)". Show your reasoning clearly.
3. Analyse why this idea matters for understanding Titration Curves — Interpreting & Analysing All Four Types: "Which regions correspond to which calculation method".
6. Extend: Apply the Idea
A student gives a memorised answer about Titration Curves — Interpreting & Analysing All Four Types 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.
