Zusammenfassung:Revised Pourbaix diagrams for Zn at concentrations of 10\+-6\- and 10\+-8\- molal included the uncharged aqueous hydrolysis complex, Zn(OH)\+v\2\-v\(aq), for the first time. Zn does not passivate at 25\0\C at 10\+-6\- M concentration of dissolved species, due to the uncharged complex. Zn passivates at concentrations of 10\+-5.7\- or above of dissolved species at 25\0\C and the oxide and not the hydroxide is the stable passive phase of Zn at 25-300\0\C.
