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 H2 Chemistry Notes: Topic 10 - Chemistry of Aqueous Solutions cover?
A: Understand ionic equilibria, solubility products, hydrolysis, complex ion formation, and qualitative analysis for the extension topic Chemistry of Aqueous Solutions.
This extension topic examines how ions behave in water-precipitation, hydrolysis, and complex formation underpin analytical chemistry questions in Papers 1–3 (and show up in Paper 4 through qualitative analysis and complex-ion work).
