Hypothesis: Which plating method did the counterfeiters use to make their coins? They used ADDITIVE PLATING to create a redox reaction between zinc solid and zinc ions. This
created neutral zinc atoms that were plated onto the copper coins.
They used DISPLACEMENT PLATING to create a redox reaction between neutral copper and zinc ions.
Electrons from copper are transferred to zinc ions, creating copper ions. The copper metal atoms are
then displaced with zinc.
