Question 2

Separation Techniques:

Answer 2

F.E.D.D
Filtration
Evaporation
Distillation
Decanting

Question 3

Filtration:

Answer 3

Passing a mixture through a filter to separate one substance from another.
USES physical prop of: Size

Question 4

Distillation:

Answer 4

Separation of liquid mixtures
Liquid with the lowest boiling point will vaporize first
Collect vapor that is then condensed and collected as pure liquid
USES the physical prop of: boiling point

Question 5

Evaporation:

Answer 5

Ex. Saltwater- water evaporates and leaves salt
USES physical prop of: Vaporization point ( evaporation/boiling)

Question 6

Decanting:

Answer 6

Separation by pouring off the liquid layer and leaving the solids behind
USES physical prop of: state of matter and Solubility
