deplating with nitric acid

[arthur kierski]

when i add nitric acid to a plated object with gold,platinum ,rhodium , i obtain foils -----palladium, silver copper and base metals goes to solution as nitrates----could someone tell me if other plated metals forms foils with nitric?

Foils form if the metal that is used for the plating is not soluble in the acid used to dissolve the metal in the interior of the object.
