Physical Separation Techniques

Question 1

Magnet

Answer 1

Based on the magnetism of certain metals

Question 2

Forceps or sift

Answer 2

Based on the size of different substances

Question 3

Solubility

Answer 3

Based on how well a substance dissolved in the same solution

Question 4

Distillation

Answer 4

Depends on the different boiling points of the components

Question 5

If something is volatile than…

Answer 5

It vaporizes faster (It will boil at low temperature)

Question 6

What does the condenser do? Distillation

Answer 6

It changes the gas back to liquid (It’s a cooled tube)

Question 7

Filtration

Answer 7

A process that separates a solid from a liquid due to their different sizes

Question 8

Evaporation

Answer 8

A process that separates a liquid from a solid based on their different boiling points

Question 9

What two phases make up chromatography?

Answer 9

Two phases: mobile phase and stationary phase

Question 10

What happens during chromatography?

Answer 10

The two different compounds have different affinities so they pass through the system at different rates

Question 11

What does a higher affinity mean? chromatography

Answer 11

A higher affinity to the mobile phase means the further it will travel up
