Abstract - The contact electric resistance of copper, silver, gold, and platinum is studied in acid, neutral, and alkaline solutions containing 10–5 to 10–2 g-ion/l of ferrocyanide-ions. Their specific adsorption at the metals begins at rather negative potentials and is competitive. The data obtained do not prove an assumption on dissociative character of the ferrocyanide-ion adsorption at the 1st Group metals.
