• Distillation

To separate substances of different particle sizes.

• Magnetic attraction

• Filtration

• Evaporation to dryness

• Distillation

To obtain a dissolved solid (solute) from a liquid (solvent).

• Magnetic attraction

• Filtration

• Evaporation to dryness

• Distillation

Separate immiscible (cannot mix) liquids with different densities.

• Use of a separating funnel

• Filtration

The particles trapped by the filter paper is known as the

The substance that has been filtered and collected in the flask is known as the

Separate substances with different boiling points through boiling and condensation.

• Simple distillation

• Fractional distillation
