Changes in surface stress of gold ribbon electrodes as a function of potential were measured in various electrolytes with an extensometer instrument. Electrocapillary‐type curves were obtained for which the change in surface stress can be equated to change in surface tension. As for mercury, the potential of the surface stress maximum for gold is independent of pH. The observed anion adsorption order on gold Was

. Experimental surface stress data and charge passed gave approximate agreement with the Lippmann equation in the electric double layer regions Formation of oxide film significantly lowered the surface stress.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
