The Electrochemistry of the First Layers of Electrodeposited Metals

“…2. The initial deposition [1] is followed by removal of the deposit [1A], and finally by a second deposition [2].…”

“…Comparing [1] and [2], it will be seen that there is much less agreement for the quantities of electricity involved in the process occurring over the range -0.4 to -0.76 volt. Fig.…”

“…5. Deposition of lead [1], followed by removal of lead [1A] and a second deposition [2] from 0.1N NaOH with 2.5 X 10 -~ mole/liter of lead. areas may be compared by measurement of the coulombs required for the production or removal of a well-defined oxide film, such as that on gold.…”

“…Oberbeck (2) and, more recently, Nichols (3) showed that an electrodeposit of copper on platinum of the order of a few atoms thick behaved as a copper electrode. Bowden (4) followed the deposition of traces of metal impurities on a mercury cathode by observing the rate of depolarization of the cathode on open circuit.…”
