Pharmaceutical Inorganic Chemistry Practicals
Teaching material only. These details are not real. These are only for teaching purposes and to make things understandable. Assumed observations and fictional cases are teaching examples, not measured results, clinical decisions, or dosing advice.
This Year 1 subject has source pages for all 6 named limit tests, 10 named assays, 3 mixture options, 4 identity options, 5 purity options, and 4 preparation options in the PCI list. The PCI requires local selection within some groups, so these are source pages for choices rather than a claim that every option is mandatory.
The articles live in this folder, one Markdown article and one labelled SVG per entry. The classical heavy-metals and arsenic exercises are document-based because their historical chemistry carries substantial hazards and does not replace modern element-specific standards. Any invented teaching calculation or observation is explicitly labelled assumed.
