Is there any way to calculate the oxidation potential of [Fe(OH)(H2O)5]+? I am unsure if it can be done since I have only seen oxidation potentials provided for specific reactions of single elements, but I want to compare the tendency of two ions to be oxidized and I don't know how to go about it.

  • $\begingroup$ It is possible, if there is possible to calculate the Gibbs energy of reaction $\ce{[Fe(H2O)6]^2+(aq) + H2O -> [Fe(H2O)5(OH)]+(aq) + H3O+(aq)}$ It could be done perhaps indirectly, if evaluated E=f(NaOH vs Fe(II) molar ratio ). $\endgroup$
