Solubility is defined as the number of grams of a solute that dissolves in 100g of a solvent to form a saturated solution at a given temperature and pressure. Solubility is the maximum weight of a solute that can be dissolved in 100g of a solvent at a given temperature and pressure.
|Solubility of solute =||Weight of solute in saturated solution||X 100|
|Weight of solvent in saturated solution|
1) Temperature - Solubility of solute increases with temperature
2) Size of solute particles-smaller the size greater the solubility of solute
3) Mechanical Stirring-solubility of solute increases with mechanical stirring.
Note: There are exceptions to the above rules, some solutes do exhibit an anomalous behaviour
Let's look at an example of solubility of a solute (solid)
The solubility of solute in gaseous form is influenced by two important parameters.
1) Temperature - Increase in temperature decreases solubility of solute in gaseous form
2) Pressure - Increase in pressure increases the solubility of gas
