Is this the SEAB Pure Chemistry 6092 syllabus?
Yes. The notes follow the SEAB O-Level Pure Chemistry syllabus, 6092 for 2026 and K324 for 2027, covering its 12 topics across 13 chapters.
Is this for Pure Chemistry or Combined Science (Chemistry)?
These notes are written for Pure Chemistry (6092). Combined Science students will find much of the content useful, but the depth follows the Pure Chemistry syllabus.
What is in each chapter?
Each chapter maps to the syllabus learning outcomes, with exam checks, worked examples and the common mistakes students make.
Does it cover qualitative analysis and the mole concept?
Yes. Qualitative analysis has its own chapter, and the mole concept sits in Chemical Calculations alongside empirical formulae, concentration and percentage yield.
