Which one of the following techniques would best be used to separate soil and water?

• Decanting
• distillation
• Filtration
• Chromatography

Which one of the following solids is insoluble in water?

• sugar
• sand
• copper sulfate
• salt

Name the separation technique shown in the diagram.

• evaporation
• distillation
•  filtration
• decanting

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

Two or more substances mingled together, but not chemically combined are known as a

• residue
• solution
• distillate
• mixture

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
• loading
• chromatography
