Entropies of Solvation for Chlorate and Nitrate Anions Can anyone find any data on the entropies of solvation for these two anions in water solution? I can't find any.
Look at the graph on p. 65, it puts the entropy of solvation (298 K) for chlorate and nitrate at about 25 and 21 kJ/mol respectively.  This reference suggests that the entropy term for nitrate is 116 J/(K-mol), multiplying that by 298 K yields 34.6 kJ/mol.
