Design a method to separate the mixture of plastic particles • Same size particles • Insoluble in water (1.0 g/mL) • Insoluble in alcohol (0.8 g/mL) Isolate the different density particles 0.7 g/mL 0.9 g/mL 1.1 g/mL PGCC CHM 101 Sinex
To isolated particles- From this mixture- PGCC CHM 101 Sinex
add water 0.7 g/mL 0.9 g/mL 1.1 g/mL PGCC CHM 101 Sinex
skim off floaters water 1.0 g/mL filter sinkers 0.7 g/mL 0.9 g/mL 1.1 g/mL PGCC CHM 101 Sinex

Suppose instead of adding water first as we just did, we added the alcohol to the mixture first. Would this work? PGCC CHM 101 Sinex
Alternative procedure- add alcohol 0.7 g/mL 0.9 g/mL 1.1 g/mL PGCC CHM 101 Sinex
skim off floaters alcohol 0.8 g/mL filter sinkers 0.7 g/mL 0.9 g/mL 1.1 g/mL PGCC CHM 101 Sinex

Follow-up questions to ponder- If these particles were water soluble, would it change your method of separation? If so, explain how. Does this open up the separation to other possible methods? Explain. PGCC CHM 101 Sinex
Does your method have to change if this was the mixture? a written version of the procedure PGCC CHM 101 Sinex
