Which sequence recovers all components, and why can another sequence leave a mixture?
A prediction is a starting idea. You can revise it after exploring.
Use at least 40 characters and include an observation. Your writing is saved as evidence; it is not automatically judged for accuracy.

This is an original Bodhi learning activity. Official references establish its curriculum context, rather than endorsement of the simulation or complete syllabus coverage.

Mapping under review · 2026-10-21A research cargo contains 8 g insoluble sand, 12 g non-volatile salt and 100 g water. Recover all three as separate collected fractions. Choose a container before each operation. The order matters: every product stays in your workspace.
Filtration retains coarse insoluble sand; dissolved salt goes through with water. Distillation separates water by vaporisation and condensation, leaving the non-volatile solids together. An operation applied to an already pure or dry fraction cannot magically separate the remaining substances.
No operation yet. Plan what each tool separates before using it.
The notebook must contain separate pure sand, pure salt and collected water. Water in an uncollected vapour fraction remains accounted for but does not meet the recovery goal.
A new cargo contains only dissolved salt and water. You must recover the water as a collected liquid, rather than letting it escape. Which method fits the goal?
Original ideal separation of coarse insoluble sand, non-volatile dissolved salt and water. Perfect filtration, complete distillation and zero transfer losses are assumed; real filter pore sizes, solubility limits, incomplete drying and carry-over are omitted. Mass is tracked even when water escapes as uncollected vapour. Distilling a mixed cargo first leaves sand and salt together, which these remaining dry operations cannot separate. This is a planning model, not a claim of drinking-water safety or a replacement for supervised apparatus work. No actual heating is involved.
