[ital In] [ital situ] x-ray scattering studies of the Au(110) electrode surface have been carried out in 0.1[ital M] NaF, NaCl, NaBr, LiCl, CsCl, and HClO[sub 4] solutions under potential control. At sufficiently negative potentials, in the salt solutions the surface forms a (1[times]3) reconstruction rather than a (1[times]2) reported for the clean vacuum surface. Above a critical threshold potential, the (1[times]3) reconstruction vanishes and the surface forms a (1[times]1) structure.
