When a solution has more than the maximum amount of solute dissolved, then it is said to be:
a
megasaturated
b
saturated
c
unsaturated
d
supersaturated
d
supersaturated
The correct answer is d) supersaturated.
Supersaturation occurs when a solution contains more solute than it can normally dissolve at a given temperature. This can happen when a hot solution is allowed to cool or when solute is added to a solution already at its maximum saturation point. In a supersaturated solution, the excess solute remains dissolved even though it is beyond its normal saturation point. This type of solution is unstable and may crystallize when disturbed or if a seed crystal is introduced.
