Why is a supersaturated solution generally considered unstable?
Answer and explanation
Correct answer: Because it contains more solute than the normal limit
A supersaturated solution contains more dissolved solute than is normally stable at that temperature. It is a metastable state, so a small disturbance, impurity, scratching of the vessel, or a seed crystal may cause the excess solute to crystallize. It is not solute-free or solvent-only, and being supersaturated does not mean the solution itself is a gas.
