In filtration, what is the name given to the solid left in the filter paper?

• filtrate
• residue
• insoluble
• condensate

In filtration, what is the name given to the liquid that passes through the filter paper?

• filtrate
• residue
• soluble

Distillation involves

• evaporation followed by melting
• evaporation followed by condensation
• condensation followed by evaporation
• melting followed by evaporation

Fractional distillation works because the liquids in the mixture have different

• solubilities
• colours
• densities
• boiling points
