Final answer:
The Solubility Curve of KNO3 increases with temperature, indicating that solubility of KNO3 in water is higher at elevated temperatures, consistent with the steep curve in the graph.
Step-by-step explanation:
The conclusion that can be drawn about the Solubility Curve of KNO3 is that it increases with temperature. This is apparent because the curve for KNO3 is described as being very steep, indicating that an increase in temperature leads to a dramatic increase in solubility. This can be observed in the solubility curve where the amount of KNO3 that can be dissolved in water is shown to increase as the temperature rises.
For example, if 80 g of KNO3 is added to 100 g of water at 30°C, approximately 48 g will dissolve, making the solution saturated. If the temperature is increased to 60°C, the solubility goes up to about 107 g, turning the solution unsaturated since the amount of KNO3 is only 80 g.
