    • Previous studies on the effect of pH on pztc values for Pt(111, as obtained from CO displacement experiments in phosphate buffer solutions, showed that pztc values remained essentially pH independent of a RHE scale. 33 This result is in contrast with the behavior observed here, with pztc values for Pt(111) shifting ca, 0.06 V/dec with the logarithm on the proton concentration. The discrepancy has two origins. First, an improved evaluation of the effect of the proton concentration on values of potential at constant charge has been employed here, based on a careful comparison of charge density data of Pt(111) in (0.1, x) M KClO4, x M HClO4solutions with and without the addition of 2.5 · 10 -3M NaCl.30 Second, more refined values of pztc are considered here, since values of potential of zero CO-displaced charge are corrected for the remaining charge on the CO-covered electrode.31 This correction dis

    • It should be noted that these results should not be taken as an indication that chemical interactions between water molecules and Pt(111) are weak. The present results only indicate that the chemical interactions between the interfacial water network and the Pt(111) surface are similar for water structures with a net orientation with the hydrogen and with the oxygen toward the metal
