O-Level Chemistry Salt Preparation Playbook (Paper 3)
Study guide
TL;DR
Salt preparation remains a core Paper 3 experiment family in the 2026 SEAB Chemistry syllabus, covering both soluble crystal growth and insoluble precipitate routes.
Planning marks depend on identifying reagents, control variables, and safe heating/drying steps, while MMO and PDO hinge on disciplined filtration, washing, and yield recording.
ACE commentary should compare theoretical versus actual yield, flag contamination risks, and cite refinements aligned with SEAB's apparatus and reagent expectations.
Sync With the Experiments Hub
Cross-reference each salt-prep drill with the O-Level Chemistry Experiments hub so your crystal workflows stay aligned with the titration, qualitative analysis, and rate investigations you’re already revising.
Salt preparation, solubility, and QA are separate routes
Use this page when the task is to prepare a salt. Use the QA table only when the task is to identify ions in an unknown.
| Search or worksheet cue | Route |
salt preparation, crystal yield, washing, drying, or recrystallisation | Stay on this playbook. |
| Solubility in excess NaOH or excess NH3 during cation testing | In-excess QA mark-trap guide |
qa table, o level qa table, cation, anion, or gas test | O-Level Chemistry QA table toolkit |
| Precipitation as a salt-preparation method | Stay here, then connect the precipitate observation back to the QA table only if the question asks for identification. |

Practical course completion-record note
For practical, lab, and experiment courses, Eclat Institute maintains centre-held attendance records and may also issue an internal attendance or completion document based on participation and internal assessment.
- For SEAB private-candidate declarations, the key evidence is the centre's attendance or completion record, not a government-issued certificate.
- 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 attend a practical course and complete it before the practical paper date.
