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

• Decanting
• distillation
• Filtration
• Chromatography

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
