Below are sample questions representative of the exercises included on this worksheet and related 8.28 Separating Mixtures by Properties skill assessments:

Problem 1Difficulty: Mastery

A student must design a separation for a mixture of saltwater and sand in a place with no electricity and no heat source.

Which plan is most workable?

ADistill the mixture

BFilter out the sand, then let the water evaporate naturally over time to leave salt

CUse a centrifuge

DUse a magnet

Solution & Explanation:Without electricity or heat, filtration can still remove sand. Salt can be recovered by slow natural evaporation, though it takes longer.

Problem 2Difficulty: Mastery

A mixture contains iron filings and a dissolved blue dye in water. You want to remove the iron without changing the dye concentration. "

Which method is best?,A. Use a magnet to remove the iron filings | B. Evaporate some water | C. Distill off the water | D. Add sand and filter,A,Magnetism removes iron filings directly and doesn’t require removing water

Problem 3Difficulty: Mastery

A mixture contains water and two insoluble solids: one sinks quickly, one stays suspended for a long time. You need both solids separated from each other.

Which plan is most effective?

AChromatography

BDistillation

CEvaporation

DAllow settling to separate the fast-sinking solid, decant, then centrifuge or filter the remaining suspension

Solution & Explanation:Use differences in settling speed (related to density/particle size): let the heavy solid settle and decant, then separate the remaining suspended solid by centrifugation or filtration.
