experimental chemistry - Copper and hydrochloric acid

Sep 09, 2015· If pure hydrochloric acid is added to a sample of pure copper, there is essentially no reaction; the solution should not turn blue. At a guess, you''re seeing the copper turn pink because it has a significant oxide layer that is reacting with the acid, forming copper (II) chloride and leaving bare the pinkish metal. The solution could be pale blue or pale green, and the time delay of the color
