Exploring Diversity of Matter Using Separation Techniques

Which method can be used to separate an insoluble solid from a liquid?

• chromatography

• evaporation

• filtration

• condensation

What is the name of the separation technique shown?

• distillation

• filtration

• evaporation

• chromatography

In evaporation, which laboratory apparatus would not be used?

• evaporating dish

• filter funnel

• bunsen burner

• wire gauze

Which would you use to separate sand from iron filings?

• a bar magnet

•  filter paper

• distillation apparatus

• chromatography paper

Dyes in water soluble markers may be separated by

• distillation

• filtration

• chromatography

• evaporation

Chromatography separates the mixture of dyes on the basis of their ----------------------------

• different density

• different solubilities in the same solvent

• differences in gravity

• different boiling points

Which separation technique is shown?

• using a magnet

• separating funnel

• centrifuging

• paper chromatography

Which is a disadvantage of evaporation?

• It always requires heat

• It cannot be used for insoluble solids

• All of the solute is recovered

• The solvent (water) is not recovered

In the distillation apparatus shown, identify parts labelled A and B.

• A = funnel, B = thermometer

• A = thermometer, B = funnel

• A = condenser, B = flask

• A = condenser, B = thermometer

The diagram shows the apparatus for separating soil and water. Identify the labelled parts.

• A = distillate, B = filtrate

• A = filtrate, B = residue

• A = residue, B = filtrate

• A = residue, B = distillate
