boiling point

Look at the apparatus setup. It cannot be used to separate which of the following mixtures?

Marble chips from oil

Alcohol and water

Chalk from sugar solution

Sand and sea water

10.

Water and alcohol are easily separated by distillation because of their

different melting points

different colours

different densities

different boiling points

11.

A liebeg condenser is used in

Filtration

Chromatography

Evaporation

Distillation

12.

When using a Liebig condenser, water goes in the (1)_________

and out the (2)_________

to cool the vapour as it passes,

condensing the vapour back to liquid form

(1) top (2) bottom

(1) bottom (2) top

13.

Can you separate salt from water using filtration?

yes

14.

Sodium chloride can be separated from rock salt by first adding water to the mixture to dissolve the sodium chloride. The separation then takes place in two stages:

evaporation followed by filtration

distillation followed by decanting

filtration followed by evaporation

filtration followed by decanting

15.

The diagram shows the apparatus for separating soil and water. What are the labelled parts?

A = residue, B = distillate

A = residue, B = filtrate

A = filtrate, B = residue

A = distillate, B = filtrate

16.

The separation technique that involves heating a solution until the liquid changes into a gaseous state, leaving behind a solid is known as

decanting

evaporation

chromatography
