Answer
Solubility:
The maximum amount of solute that can be dissolved in a solvent to form a saturated solution at a specific temperature is called the “Solubility”.
Molar solubility
Molar solubility refers to the number of moles of a substance that can be dispersed in one liter. It can be expressed in mol/L (molarity) or M (molarity).
Common ion effect:
Common ion effect refers to the solubility in a salt that is partially soluble and decreases when it is added to a salt that contains an ion.
Take a look at the following general reactions:
