1
Understand the concept of solubility: Solubility is the maximum amount of solute that can dissolve in a solvent at a specific temperature to form a stable solution.
Recognize the types of solutions based on solute concentration relative to solubility: unsaturated (less solute than maximum), saturated (solute amount equals maximum solubility), and supersaturated (more solute than the maximum solubility).
Identify that a supersaturated solution contains more dissolved solute than the equilibrium solubility limit at that temperature, making it unstable and prone to crystallization.
Compare the given options to the definitions: the correct description of a supersaturated solution is one that contains more dissolved solute than it can theoretically hold at a given temperature.
Conclude that the other options describe unsaturated, saturated, or undissolved solute conditions, which do not match the definition of a supersaturated solution.
