Abstract
The various methods proposed and used in the past for the determination of the absolute potentials are reviewed and discussed at length. The more recent methods based on the production of fresh metal surfaces give a more reliable value (εH = + 0.475 volt) which fits in better with our modern physical and chemical conceptions. The older value (εH = − 0.277 volt) is shown to be out of harmony with these conceptions. Experiments are recorded to show that the older methods (εH = − 0.277 volt) are misleading. The new scrape method of Bennewitz is recommended as being the most trustworthy one (εH = + 0.475 ± 0.005 volt).Keywords
