 Hi There,
 Is anyone aware of successes in reproducing some of the
 tabulated redox potentials of electrochemical reactions that
 ar elisted i standard electrochemical tables, especiall those
 involving single ions? e.g. Cu
 --> Cu2+(aq) + 2e-. The key issue that I need coment on here is the
 selection of appropriate solvation models. I doubt if
 continuum models would require inclusion of at least the
 first shell of water molecules, as these are strongly bound.
 As a starting point I am trying to reproduce the experimental
 value of the 'reference' reaction 2H+ +2e = H2. Even this
 appears tricky.
 Thanks in advance,
 Noko Phala, Anglo Research
