When we dissolve a solute in a solvent, a solution is formed. We can make many different solutions by changing the amount of solute added in the solvent.

Example : We can make many salt solutions by adding more and more salt to the water.

But... there will come a point when adding more salt to the solution doesn't dissolve. That's when we have a Saturated Solution.

## What is a Saturated Solution?

A solution in which no more solute can be dissolved without raising its 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

Let's look at Unsaturated Solutions , and the Difference between Saturated and Unsaturated Solutions
