In the context of solutions, what best describes a saturated solution at a given temperature?
A
A solution in which the solvent has completely evaporated, leaving only solid solute
B
A solution that contains the maximum amount of solute that can dissolve, with any additional solute remaining undissolved in equilibrium
C
A solution that contains no dissolved solute
D
A solution that can still dissolve more solute without changing conditions

Understand the concept of a saturated solution: it is a solution that has dissolved the maximum amount of solute possible at a given temperature.
Recognize that at saturation, the solution is in dynamic equilibrium, meaning the rate of solute dissolving equals the rate of solute crystallizing or precipitating out.
Note that any additional solute added beyond this maximum amount will remain undissolved, as the solution cannot hold more solute under the current conditions.
Distinguish this from unsaturated solutions, which can dissolve more solute, and from solutions where the solvent has evaporated, which is a different scenario.
Therefore, a saturated solution is best described as one that contains the maximum amount of solute dissolved, with excess solute undissolved and in equilibrium with the dissolved solute.
