Physical Separation Techniques

Question 1

What types of mixtures does HS separate

Answer 1

Large solids from other mixtures

Question 2

What types of mixtures does F separate

Answer 2

Suspended solids

Question 3

What types of mixtures does E separate

Answer 3

Solutions

Question 4

What type of mixture does D separate

Answer 4

Liquid in liquid or Solid in liquid

Question 5

What types of mixtures does GS separate

Answer 5

Solid in solid or solid in liquid

Question 6

What types of mixtures does C separate

Answer 6

Solid in solid, solid in liquid, liquid in liquid

Question 7

How does HS separate things

Answer 7

Size (hand/sieve) or Magnetism (magnet)

Question 8

How does F separate things

Answer 8

Solubility/particle size (anything bigger than filter holes will get stuck)

Question 9

How does E separate things

Answer 9

Ability to change phase (solvent evaporates, solids are left)

Question 10

How does D separate things

Answer 10

Based on boiling point

Question 11

How does GS separate things

Answer 11

Based on density (needs to be different)

Question 12

How does C separate things

Answer 12

Attraction to mobile vs stationary phase

Question 13

What parts are you able to keep in HS

Answer 13

Everything

Question 14

What parts are you able to keep in F

Answer 14

Both parts Residue and Filtrate

Question 15

What parts are you able to keep in E

Answer 15

Solids (not solvents)

Question 16

What parts are you able to keep in D

Answer 16

All parts

Question 17

What parts are you able to keep in GS

Answer 17

All parts

Question 18

What parts are you able to keep in C

Answer 18

Solids

Question 19

What equipment is needed for HS

Answer 19

Sieve or magnet

Question 20

What equipment is needed for F

Answer 20

Filter paper, Funnel, something to catch filtrate

Question 21

What equipment is needed for E

Answer 21

Time, heat source, solvent

Question 22

What equipment is needed for D

Answer 22

Thermometer, distilling flask, Burner, condenser, receiving flask

Question 23

What equipment is needed for GS

Answer 23

Time or centrifuge

Question 24

What equipment is needed for C

Answer 24

Stationary phase (paper, column, etc
Mobile phase (must be able to dissolve solid)

Question 25

Addition notes for E

Answer 25

Can heat to increase initial evaporation (but do not boil to dryness)

Question 26

Additional notes for D

Answer 26

Closer boiling points can require extra distillations to purify

Question 27

Additional notes for GS

Answer 27

Solid in liquid only works for small amount of liquid
