Types of Aqueous Solutions
객관식
In the context of types of aqueous solutions, which statement best describes an unsaturated solution at a given temperature?
A
It has no solute dissolved in the solvent (pure water only).
B
It contains the maximum amount of dissolved solute possible and is in dynamic equilibrium with undissolved solute.
C
It contains more dissolved solute than is normally possible at that temperature and is unstable.
D
It contains less than the maximum amount of dissolved solute possible, so more solute can still dissolve.
검증된 단계별 안내1
Understand the concept of saturation in aqueous solutions: Saturation refers to the point at which a solution contains the maximum amount of dissolved solute at a given temperature.
Define an unsaturated solution: It is a solution that contains less solute than the maximum amount that can dissolve at that temperature, meaning more solute can still dissolve.
Contrast with a saturated solution: A saturated solution contains the maximum amount of solute dissolved and is in dynamic equilibrium with any undissolved solute present.
Contrast with a supersaturated solution: A supersaturated solution contains more solute than normally possible at that temperature and is unstable, often leading to crystallization.
Recognize that a solution with no solute dissolved (pure solvent) is not considered unsaturated but simply a solvent without solute.
