What is meant by Solubility?
The maximum amount of the solid that can be dissolved in a given amount of the solvent (water) is termed its solubility at that temperature.
Numerically, it is 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.
