Practical course certificate note
For practical, lab, and experiment courses, Eclat Institute may issue an internal Certificate of Completion/Attendance based on participation and internal assessment.
- This is an internal centre-issued certificate, not an MOE/SEAB qualification or accreditation.
- Recognition (if any) is determined by the receiving school, institution, or employer.
- For SEAB private candidates taking science practical papers, SEAB states you should either have taken the subject before or complete a practical course before the practical exam date.

Q: What does Qualitative Analysis & Organic Workflow for H2 Chemistry Paper 4 cover?
A: A structured workflow for inorganic qualitative analysis and small-scale organic tasks—covering planning scripts, observation logging, and ACE commentary aligned with SEAB’s 2026 practical expectations.
TL;DR
Paper 4 still leans on qualitative analysis (QA) and organic workups. SEAB supplies QA notes during the exam, but you must plan reagent sequences, manage heating safely, and phrase observations precisely.
Use decision trees, log colours/precipitates accurately, capture confirmatory tests, and evaluate contamination or reagent freshness in ACE write-ups.
Status: SEAB H2 Chemistry (9476) syllabus and 9476/04 specimen paper last checked 2026-01-13. Paper 4 is 2 h 30 min, 50 marks, weighting 20 % with Planning at 4 % and MMO/PDO/ACE at 16 % combined; qualitative analysis and simple organic tasks stay within the practical scope and QA notes continue to be supplied in-exam.
Code note: 2026 resources use 9476; older notes may still reference 9729.

1 | QA and organic tasks in Paper 4
- The SEAB 2026 H2 Chemistry syllabus (9476) highlights qualitative inorganic analysis (cations/anions, gas tests) and simple organic synthesis/purification as recurring Paper 4 contexts.
- Paper 4 lasts 2 h 30 min, carries 50 marks, and is weighted at 20% of the H2 grade; Planning accounts for 4% while MMO/PDO/ACE share the remaining 16% combined.
- Qualitative Analysis notes are provided, but candidates must choose the correct reagents, order of tests, and safety precautions without prompting.
2 | Planning scripts that score
Structure planning responses around:
- Aim and identity hypotheses — e.g., “Identify cations in sample A; suspected Group II ion based on context.”
- Test sequence — state preliminary checks (flame test, carbonate test), followed by confirmatory reagents (NH₃(aq), NaOH(aq), anion tests). Justify order to minimise cross-contamination.
- Volumes and apparatus — indicate droplet counts, heating method (water bath, sand bath), and glassware.
