Saturated Solution | Unsaturated Solution |
Solution contains the maximum amount of dissolved solute | Solution contains less than maximum amount of dissolved solute |
More solute cannot be added without raising the temperature | More solute can be added without raising the temperature |
Example : Solubility of Salt is 36gm (at 20 degree celsius)
| Example : Solubility of Salt is 36gm (at 20 degree celsius)
(Anything less than 36 gm would work) |
Note : A supersaturated solution contains more than the maximum amount of solute that can be dissolved at that temperature. It is unstable and the solute will usually begin to crystallize, especially if disturbed.
Example : A solution of 40g Salt in 100 g water is Super Saturated Solution

Hint: This question gives the knowledge about the saturated, unsaturated solutions and suspension. Saturated solutions are the solutions in which no more solute is added at a particular given temperature. A solution is generally a mixture of solute and solvent.
Complete step by step answer:
Saturated solutions are the solutions in which no more solute is added at a particular given temperature. An important example of a saturated solution is carbonated
water.
Properties of saturated solution is as follows:
$1$. The solubility of an unsaturated solution increases on heating or on increasing the temperature.
$2$. On lowering the temperature, the dissolved substances or solutes present in the unsaturated solution leads to the formation of precipitate.
Unsaturated solutions are the solutions in which more solute is added at a particular given temperature. The important example of an unsaturated solution is mixing of salt in
water.
Properties of unsaturated solution is as follows:
$1$. The solubility of a saturated solution increases on heating or on increasing the temperature.
$2$. On lowering the temperature, the dissolved substances or solutes present in the unsaturated solution leads to the formation of precipitate.
Suspension is defined as the solution in which solid particles do not dissolve in the liquid and spread throughout the liquid. The example of suspension is milk of magnesia, muddy water
and so forth. The particles of suspension are visible through naked eyes.
Note:
Always remember that a solution is generally a mixture of solute and solvent. The saturated solution is a type of solution in which no more solute is added at a particular given temperature. The unsaturated solutions are the solutions in which more solute is added at a particular given temperature.
