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.
