An experiment is performed to test the effect temperature has on the solubility of potassium nitrate. The following data were recorded.
Temperature (°C) = 0.0, 12.5 , 23.0, 41.5
Volume of solution (mL) = 10.0, 10.0, 10.0, 10.0
Mass of solute dissolved (g)= 1.25, 2.2, 3.28, 6.78
Interpretation of the data shows that, as the temperature of a potassium nitrate solution decreases, the solubility _______
