Final answer:
Without the specific solubility of KCIO2 at 30°C provided, we cannot confirm if a solution with 20 grams of KCIO2 and water is unsaturated, saturated, or supersaturated. Solubility curves are necessary to make this determination.
Step-by-step explanation:
To determine whether a solution is unsaturated, saturated, or supersaturated, solubility curves can provide necessary information. When a solute is added to a solvent and it dissolves completely without any excess, we have an unsaturated solution. For a saturated solution, the amount of dissolved solute is at its maximum capacity at a given temperature, and no more solute can dissolve. If the solution has more solute dissolved than what is normally possible at that temperature, often achieved by changing the temperature, it is known as a supersaturated solution.
With the example of adding 20 grams of KCIO2 to water at 30°C, without a specific solubility curve for KCIO2, we cannot definitively state whether the solution is unsaturated, saturated, or supersaturated. However, if we compare this to the given KNO3 scenario, we understand that to make this determination, one would need the solubility of KCIO2 at 30°C. If 20 grams is less than the maximum solubility at 30°C, the solution would be unsaturated, but if it is more, the solution could be saturated or even supersaturated.
