Filtration is the separation of a solid from a fluid by passing the mixture through a medium through which only the fluid can pass.
In gravity filtration, a suspension of a solid in a liquid is allowed to flow by gravity through a porous medium such as a filter paper.
The liquid passes through the pores in the paper, and the solid is retained on the paper.
Vacuum filtration is often used to speed up the filtration process.
The filter paper is placed over the perforated base of a Hirsch or Büchner funnel, and a vacuum is applied to help pull the liquid through the paper.
