What is a Saturated Solution?
A solution in which no more solute can be dissolved without raising temperature / at a given temperature is called saturated solution.
The maximum amount of solute that can be added is called the saturation level. Amount of solute in a saturated solution at a given temperature is called Solubility.
Example
Solubility of Salt is 36gm (at 20 degree celsius)
It means if we mix 36 gms of salt in 100 gm of water, it forms 136 gm of saturated solution
If we mix more salt in this solution, it will not dissolve and remains undissolved at the bottom.
However, if we increase the temperature, it will dissolve
