Separating mixtures

Filtration is recommended for separating all of the following mixtures, except for one, which one?

• Impurities in water

• sugar and sand

• salt and soil

• syrup and molasses

All of the following are examples of evaporation except for one, which one?

• the formation of bubbles as water boils

• the sun drying a wet yard

• water forming on a bathroom mirror

• clothes drying on a washing line

The disadvantage of evaporation is that:

• all the solute is recovered

• the solvent evaporates

• the solute is called residue

• the solvent cannot be recovered

It is possible to separate water and alcohol using distillation because of their difference in:

• Boiling temperatures

• Melting points

• Boiling densities

• Colour

All of the following pieces of apparatus are needed to demonstrate evaporation in the laboratory, except for one. Which one?

• water bath

• wire gauze

• Bunsen Burner

• filter funnel
