Filtration Process and Techniques

The video tutorial explains the process of filtration, aiming to separate solid particles from liquids or gases. It lists the required materials, including a funnel, beaker, glass rod, filter paper, and distilled water. The procedure involves folding the filter paper, fitting it into a funnel, and pouring the liquid with impurities through it to filter the solution. Precautions include careful handling of glass apparatus and maintaining safety measures in the laboratory.

What is the primary goal of the filtration process?

• To evaporate liquids

• To dissolve gases in liquids

• To separate solid particles from fluids

• To mix solid particles with liquids

Which of the following is NOT a material required for the filtration experiment?

• Bunel

• Glass rod

• Tripod stand

• Bunsen burner

How should the filter paper be folded to form a cone?

• Fold it into thirds and then into a cone

• Fold it in half twice and then into a cone

• Fold it into quarters and then into a cone

• Fold it in half once and then into a cone

What is the purpose of wetting the filter paper with water?

• To dissolve the impurities

• To ensure the paper fits tightly against the funnel

• To make the paper more transparent

• To increase the filtration speed

Where should the funnel be placed during the filtration process?

• Inside a closed container

• Directly on the table

• On a flat surface

• Above an empty beaker on a tripod stand

What is the role of the glass rod in the filtration process?

• To stir the solution

• To support the funnel

• To guide the liquid into the funnel

• To measure the liquid

What should be done if the stem of the funnel is not filled with water?

• Stir the solution

• Remove the funnel

• Add more water

• Add more powder impurities

Which precaution is NOT mentioned for the filtration experiment?

• Maintain safety measures

• Fold filter paper carefully

• Wear protective gloves

• Use glass apparatus carefully

Why is it important to maintain safety measures in the laboratory?

• To prevent accidents and ensure safety

• To ensure the experiment is completed quickly

• To make the experiment more interesting

• To reduce the cost of materials
