Electrocapillary Studies on Partially Immersed Mercuryhyphen;Plated Electrode in DMFhyphen;Water Solutions

摘要

Meniscus rise vs potential studies were carried out on a mercuryhyphen;plated gold electrode in DMFhyphen;water media. The magnitude as well as the variation of the meniscus minimum with the nature and electrolyte concentration correspond to the electrocapillary maximum of mercury in the same solutions. The interfacial tension and surface charge calculated from the meniscus rise data agree with their corresponding values obtained from directly measured electrocapillary curves on liquid mercury. Possible explanations for the lower interfacial tensions values calculated from the meniscus rise data in aqueous solutions are given.
