The Role of Sulphuric Acid in Copper Plating

The more sulfuric acid you add the better is your throwing power for example a usual copper electrolyte contains about 60 g/l Sulfuric acid a copper electrolyte for plating printed circuit which have very small holes to plate in contains about 220 g/l Sulphuric acid

experimental chemistry

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
