Adsorption of Gases on the Surface of Mercury

  title={Adsorption of Gases on the Surface of Mercury},
  author={M. Oliphant and R. S. Burdon},
CERTAIN methods of measuring the surface tension of mercury, especially the ‘big-drop’ method as used by Popesco (Ann. de Physique, 3, p. 402; 1925), appear to show that the presence of air or other gas increases the surface tension of a freshly formed surface by about 100 dynes. The ‘drop-weight’ method, on the other hand, shows a difference of only a few dynes between the values in air and in vacuo, and this indeed in the opposite sense to that indicated above (Harkins, Jour. Am. Chem. Soc… Expand

Adsorption of gases on mercury
A mercury surface was formed in the presence of a gas and the gas was pumped off after an interval. The mercury surface was then caused to collapse. This caused an evolution of gas which was measuredExpand
Pitting of plain carbon steels in acidic solution
Abstract The “end grain” pitting of plain carbon steels by acid pickling solutions is initiated by rapid dissolution of the sulphide inclusions. This is followed by simple dissolution of the metalExpand
