Phase Interface - an overview ScienceDirect Topics

Every phase boundary of a true aqueous phase diagram consists of a series of (pH, Eh) coordinates.Hence, after a true phase diagram has been calculated, the phase boundaries can be replotted in Eh-pH coordinates.As an example, Fig. 11.6 is replotted in Eh-pH coordinates in Fig. 11.13.It must be stressed that such a diagram cannot be called “the Eh-pH diagram of the H 2
