Abstract
The electrodeposition behavior of a trace on an inert electrode can be described by the unabridged form of the Nernst equation after it has been modified by the addition of a term to account for energy differences at the deposit‐electrode interface. Both the original and the modified Nernst equations predict that, in dealing with amounts of depositable element insufficient to cover completely the inert electrode, the percentage of an ion deposited at any specific potential is independent of the amount of element present, but is dependent upon the area of the electrode and the volume of the solution.
