EXAMPLE  - Predicting the Effect of Temperature on Solubility:

Would you expect the water solubility of the following substances to be higher or lower at 100 C than at 20 C?

a. acetaminophen (the pain reliever in Tylenol) melting point = 169-170 C

b. dimethyl ether (used as a refrigerant) melting point = -138.5 C,
                                boiling point = -25 C

Solution:

a. Higher Because acetaminophen is a solid at room temperature, we expect its solubility to increase with increasing temperature.

b. Lower Because dimethyl ether is a gas at room temperature, we expect its solubility to decrease with increasing temperature.
