The purpose of a filter paper inside a beaker is to retain the suspended solid particles found in the solution.
<em>The retention capacity of the filter paper will depend on the size of the pores of the filter</em>. Thus, for example, if the pores of the filter have a diameter of 1 mm, particles with a diameter greater than 1 mm will be retained, and the rest of the solution will pass through the pores.
The removal of impurities through filters is a physical separation process.
