Filter medium: This is the material through which the mixture is passed. It may be a porous material, such as filter paper, or a physical barrier, such as a mesh screen.
Filtrate: The liquid that passes through the filter medium and is collected below it.
Residue: The solid particles that are retained by the filter medium and collected on top of it.
Filtration apparatus: This includes a funnel, filter paper, and a container to collect the filtrate.
Steps in Filtration
Place the filter medium (e.g., filter paper) in a funnel, and set the funnel in a container to collect the filtrate.
Pour the mixture to be filtered into the filter paper. The liquid will pass through the filter paper, leaving the solid particles behind.
Collect the filtrate in the container below the filter paper.
Remove the residue from the filter paper and dry or further process it if needed.
Applications of Filtration
Filtration is widely used in various fields, including:
Use mathematics and computational thinking to express the concentrations of solutions quantitatively using molarity.
Use the concept of pH as a model to predict the relative properties of strong, weak, concentrated, and dilute acids and bases (e.g., Arrhenius and Brønsted-Lowry acids and bases).
