If you scan the values for S° in Appendix E, you will see that some aqueous ions have values that are less than zero. The third law of thermodynamics states that for a pure substance the entropy goes to zero only at 0 k. Use your understanding of the solvation of ions in water to explain how a negative value of S° can arise for aqueous species.
