Question

The component of a solution cannot be separated by filtration. explain.

Answer 1

• Solution: A homogeneous mixture of two or more substances is called a solution.
• A solution may be a liquid that contains either a solid or a liquid or a gas dissolved in it.
• A solution can also have a solid solution and gaseous solution as in the case of alloys and air respectively.
• A true solution is always clear and transparent. light can easily pass through it without scattering.
• The particles of a solute break down to almost molecular size and their diameter is of the order of 1 nm (10^-9m) or less.
• In a true solution, the particles of solute do not settle down, provided the temperature is constant.
• From a true solution, the solute can easily be recovered by evaporation or crystallization.

A true solution can completely pass through a filter paper as the particle size of the solute is far smaller than the size of the pores of filter paper. so their component cannot be separated by filtration
