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.

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
