A supersaturated solution is said to contain
more solute than it can dissolve at that temperature in the presence of undissolved solute
as much solute as it can dissolve at that temperature in the presence of undissolved solute
as much solute as it can dissolve at that temperature
more solute than it can dissolve at that temperature
설명
The correct answer is D. More solute than it can dissolve at that temperature.
A supersaturated solution is a solution that contains more dissolved solute than it can hold at equilibrium at a given temperature. This means that the solution is unstable and can precipitate out the excess solute at any moment.
In contrast, a saturated solution (option C) contains as much dissolved solute as it can hold at equilibrium at a given temperature, while an unsaturated solution contains less dissolved solute than it can hold.
