Understanding Distillation and Filtration

The video tutorial explains two methods of separating mixtures: distillation and filtration. Distillation is used to obtain pure liquid from a solution by heating it until the liquid evaporates and then condensing the vapor back into a liquid, leaving the solid behind. An experiment with salt water is demonstrated to illustrate this process. Filtration is used to separate insoluble solids from liquids by pouring the mixture through a filter, which traps the solid and allows the liquid to pass through. An experiment with sand and water is shown to explain this method.

What is the primary purpose of distillation?

• To mix different liquids together

• To obtain pure liquid from a solution

• To separate insoluble solids from liquids

• To cool down a heated solution

In the distillation experiment, what is left behind in the retort?

• Water

• Steam

• Salt

• Sand

What happens to the steam in the distillation process?

• It evaporates into the air

• It condenses into water droplets

• It mixes with the salt

• It remains in the retort

What is the purpose of folding the paper into a cone in the filtration experiment?

• To heat the solution

• To collect the sand

• To act as a filter

• To evaporate the water

What is the clear water collected in the filtration process called?

• Filtrate

• Solvent

• Distillate

• Residue

Which method is used to separate insoluble solids from liquids?

• Filtration

• Evaporation

• Distillation

• Condensation
