Abstract

Peculiar dendritic deposits of mercury were obtained galvanostatically from the mercurous nitratemethanol-water system at −50° C. These deposits could not be maintained at a constant shape because, when the current was interrupted, they transformed and shrank immediately to a spherical shape with hydrogen evolution. It seems that when the electrical potential was removed, the mercury deposits liquefied and the hydrogen stored in them was released during the period of shrinking.
