Separation techniques

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

• A = distillate, B = filtrate
• A = filtrate, B = residue
• A = residue, B = filtrate
• A = residue, B = distillate

To separate a mixture of salt and water what separation method is used?

• Filtration

• Distillation

• Chromatography

• Evaporation to dryness

Which separation technique uses the apparatus shown in the diagram?

• filtration

• evaporation

• distillation

• chromatography

What is the boiling point of water?

• 0^oC
• 100^oC
• 80^oC
• 95^oC

Water and alcohol are easily separated by distillation because of their

• different densities
• different boiling points
• different colours
• different melting points

Which of the following pairs of substances may best be separated through through fractional distillation

• sand and soil

• water and soil

• salt and sand

• water and alcohol

A solution that contains a large amount of solute is best described as 

• unsaturated
• concentrated
• dilute
• weak

Dyes in water soluble markers may be separated by means of

• Simple distillation

• Crystallisation

• Chromatography

• Filtration

Which property indicates that a solid is pure?

• It burns completely in oxygen, leaving no residue.

• It has a fixed melting point.

• It has a fixed volume.

• It is soluble in water.

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
