- 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,
point = -25 C
Because acetaminophen is a solid at room temperature, we expect its
solubility to increase with increasing temperature.
Because dimethyl ether is a gas at room temperature, we expect its
solubility to decrease with increasing temperature.
