* No more solute will dissolve. A saturated solution is already holding the maximum amount of solute that can dissolve at that specific temperature and pressure.

* The excess solute will settle at the bottom. This is because the solution has reached its solubility limit.

* The solution remains saturated. The concentration of the dissolved solute won't change, even if there's undissolved solute present.

In summary: Adding more solute to a saturated solution doesn't change the concentration of the dissolved solute, but it results in excess solute settling at the bottom.
