A saturated solution is a mixture where a solvent (usually water) has dissolved as much solute as it can at a given temperature. No more solute can dissolve, and any extra stays undissolved at the bottom.
For example, when adding sugar to tea, it will dissolve until the solution becomes saturated—after that, extra sugar won’t dissolve and settles at the bottom.
The amount of solute that can dissolve depends on the temperature:
At higher temperatures, more solute can usually dissolve
At lower temperatures, some solute may crystallise out
Saturated solutions are important in GCSE Chemistry for understanding solubility, crystallisation, and solution concentration.
