The smaller the size of the solute particle, the greater is the solubility.
How the size of the solute impacts the solubility?
- The maximum amount of a substance that can be dissolved in a given volume of solvent is called solubility.
- A solution that has reached the maximum solubility is called a saturated solution. If more solute is added at this point, it will not dissolve into the solution.
- The larger the molecules of the solute are, the larger is their molecular weight and their size. It is more difficult it is for solvent molecules to surround bigger molecules.
- If the particle size is small, then the solubility will be more.
