ANSWER:
Solution:
The solution is unsaturated
Explanation:
Step 1
Saturated, means that no more of a given compound can be dissolved in the given solvent. i.e. if something has a solubility of 10 g/L and you have 10 g in a liter, it is saturated.
Supersaturation means going beyond the saturation point. So adding more than is possible. This means, practically, that saturation has been achieved and there is still some solid left in suspension. This often occurs with temperature change, or in a lab situation to ensure saturation.
Unsaturated means that you simply have not added the as much solute as is needed for saturation.
