Publisher's Synopsis
Excerpt from An Investigation of Zinc Amalgams and Concentration Cells: A Thesis Submitted to the Faculty of Princeton University in Partial Fulfilment of the Requirements for the Degree of Doctor of Philosophy
One of the most serious difficulties encountered by previous investigators has been due to a loss of zinc from the amalgams by oxidation and unless this difficulty is overcome the results are not reliable. The more recent workers paid a great deal of attention to this point, but they were not in a position to know just how successful their precautions were since they were measuring the electromotive force of these amalgams in a concentration cell and this magnitude depends on the rela tive and not on the absolute concentrations of the amalgams so that there might have been a loss of zinc from all of the amalgams in the cells and, provided this loss in each case was proportional to the concentration, there would have been no Change in the electromotive forces of the cells.
