H2 Chemistry Paper 4 Lab Revision Checklist
A last-mile H2 Chemistry 9476 Paper 4 lab revision checklist for titration, QA, kinetics, energetics, gas collection, uncertainty, planning, and ACE.
The core idea is simple: Paper 4 revision should end with lab actions, not more notes.
Use it as a working check: Rotate titration, QA, kinetics, energetics, gas collection, uncertainty, planning, and ACE.
Then go one layer deeper: For each technique, write the setup, raw data table, calculation route, and one targeted improvement.
H2 Chemistry Paper 4 is a 2 h 30 min practical paper worth 50 marks. SEAB's 9476 syllabus places Planning at 4% of the subject grade and MMO, PDO, and ACE at 16% combined.
Use the H2 Chemistry Paper 4 format guide when you need the full structure. Use this checklist when the exam is close and you need to decide what to rehearse in the lab next.
Choose the next lab drill
| If your weak spot is... | Practise this next | Evidence to write down |
| Titre spread | Full titration run | Initial reading, final reading, titre, concordance, average |
| Vague QA answers | One unknown salt route | Exact colour, precipitate, solubility, gas test, inference |
| Slow kinetics setup | One rate experiment | Time variable, concentration variable, graph choice |
