One of the standard tests for Copper cleanliness is simply to drop some
standard 0.1N Silver Nitrate titating solution on to the Copper. If the
Copper is clean, the Silver Nitrate turns black almost immediately. If there
are soils present, the copper remains pink/orange.
Is this what you were referring to??
