Gold service : The asperities on a polished gold surface are quickly dissolved by the OH . radicals of Fenton's reagent. The dissolution of Au is rapid at the beginning of the reaction and is negligible when the asperities have been dissolved. Although the OH . radicals also oxidize the smooth parts of the Au surface, they do not dissolve them, but form a stable oxide monolayer.
