Which of the physical properties is/are used for separation of the components of a mixture by filtration?
(a) boiling points
(b) the abilities of the compounds to absorb
(c) solubility

The correct answer is option 'c' : Solubility.

Explanation:

When we mix any 2 substances the resultant mixture may be in a single phase i.e the two substances dissolve completely forming a new substance e.g when salt is dissolved in water of may result in a 2 phased system like when soil is added to water.

The substance that we add is known as solute and the substance to which the solute is added is known as solvent.

Solubility is defined as the ability of the solute to mix in a solvent. If the solute and the solvent does not mix the 2 phases can be separated by filtration

Filtration works when there is a clear distinction of solute and the solvent like when we add sand to water the sand does not dissolve in the water and hence can be blocked by a filter paper through which it is passed while carrying out filtration.
