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.
Equilibrium is achieved when the reaction rate of the forward and backward reaction are equal or the concentrations of the reactants and the products are in an unchanging ratio. Specifically, this system is in a dynamic equilibrium.
