Concept:A saturated solution represents a state of dynamic equilibrium between the solid phase and the aqueous phase of a solute.
Formula:$$ \text{Solute}_{(s)} \rightleftharpoons \text{Solute}_{(aq)} $$
Solution:- In a saturated solution, the maximum amount of solute has dissolved at a given temperature.
- Any additional solute added will simply sink to the bottom.
- At this exact point, the rate of dissolution (solid turning to aqueous) perfectly equals the rate of crystallization (aqueous turning back to solid).
- This defines a state of equilibrium.
Why other options are incorrect:Unsaturated solutions have not reached equilibrium yet (more can dissolve). Supersaturated solutions are highly unstable and technically past the equilibrium point until precipitation occurs.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
