Dear list members, Ethan Grossman and I are working on an isotopic study of
a sulfate-reducing aquifer.  We have sulfate, sulfite, and sulfide

concentration data, but we do not have any relevant thermodynamic data for
sulfite to test for chemical equilibrium.  Does anyone out there know if such
data exists and if so, where we can find it?  Thanks, T.C. Onstott
