{ital In} {ital situ} x-ray scattering studies of the Pt(110) electrode show that a stable (1{times}2) reconstruction is present over a wide electrode potential range and that the topmost rows of Pt atoms are expanded into the electrolyte. Additional expansion occurs upon the potential-induced adsorption of hydroxyl or hydrogen atoms. The presence and stability of the (1{times}2) reconstruction have an important influence on some of the surface reactions that can occur in electrolyte. {copyright} {ital 1996 The American Physical Society.}
