Question 1

Filtration

Answer 1

Filtration is used to separate an insoluble solid from a liquid. To do this, place filter paper in a funnel over a conical flask. Pour the mixture of solid and liquid into the filter paper. The liquid passes through and collects in the flask; this is called the filtrate. The solid is trapped in the filter paper; this is called the residue.

Question 2

Evaporation

Answer 2

Evaporation is used to separate a soluble solid from a liquid. Pour the solution into an evaporating basin. Gently heat the basin with a Bunsen burner. The liquid will evaporate, turning into a gas and leaving the solid behind in the basin.

Question 3

Simple Distillation

Answer 3

Simple distillation is used to separate a liquid from a solution. Place the solution in a flask attached to a condenser. Heat the flask. The liquid boils and turns into a gas. The gas travels into the condenser where it is cooled and turns back into a liquid. This pure liquid, called the distillate, is collected in a separate beaker.
