Mixed FeFe hydroxides, commonly referred to as 'green rusts' (GRs), are important reactive phases in both man-made and natural geochemical systems. Determinations of the standard Gibbs energy of formation of GRs are needed to understand and predict the occurrence and possible reactions of GRs inthese systems. [...]
