Answer: A saturated solution is a solution with as much dissolved solute as it can hold at a given temperature.
Step-by-step explanation:
Saturated solution: It is a solution in which solute is dissolved in its maximum amount in a solvent at a given temperature. Further addition of solute will not get dissolve in the solution. For : Soda is a saturated solution of carbon-dioxide in water.
Unsaturated solution: It is a solution in which addition of more solute will get easily dissolve in a solution at a given temperature. In unsaturated solution the amount of solute present in less than the amount of solute present in saturated solution. For example: Pinch of salt in a glass of water.
