Which statement best describes a supersaturated solution according to solubility rules?
A
A solution that contains more dissolved solute than it can theoretically hold at a given temperature.
B
A solution that contains less solute than the maximum amount that can dissolve at a given temperature.

Verified step by step guidance1
Step 1: Understand the concept of solubility and saturation. Solubility is the maximum amount of solute that can dissolve in a solvent at a specific temperature to form a stable solution.
Step 2: Define a saturated solution. A saturated solution contains the maximum amount of dissolved solute that can be held at that temperature, meaning no more solute can dissolve.
Step 3: Define an unsaturated solution. An unsaturated solution contains less solute than the maximum amount that can dissolve at that temperature, so more solute can still dissolve.
Step 4: Define a supersaturated solution. A supersaturated solution contains more dissolved solute than the theoretical maximum solubility at that temperature, which is usually achieved by changing conditions such as cooling a saturated solution carefully.
Step 5: Apply these definitions to the given options and identify that the statement describing a supersaturated solution is: 'A solution that contains more dissolved solute than it can theoretically hold at a given temperature.'
