Which of the following best describes a liquid at its saturation point?
A
It can still dissolve more solute without any undissolved particles forming.
B
It has reached a temperature where the solute begins to evaporate.
C
It contains no dissolved solute and is completely pure.
D
It contains the maximum amount of dissolved solute possible at a given temperature, with any additional solute remaining undissolved.
Verified step by step guidance1
Understand the concept of saturation point: A liquid at its saturation point contains the maximum amount of solute that can dissolve at a specific temperature and pressure.
Recognize that beyond this point, any additional solute added will not dissolve and will remain as undissolved particles in the solution.
Note that the saturation point is temperature-dependent; increasing temperature often allows more solute to dissolve, while decreasing temperature reduces solubility.
Distinguish saturation from other states: a solution that can still dissolve more solute is unsaturated, and a solution with no dissolved solute is pure solvent, not saturated.
Therefore, the best description of a liquid at its saturation point is that it contains the maximum amount of dissolved solute possible at that temperature, with any extra solute remaining undissolved.
