We can predict and calculate "potential" voltage by finding the
difference in potential between a cathode and anode. To do this
simply subtract the "potential" for each metal :
Voltage= Cathode - Anode
Question: Use the potentials listed in the table to check your
combinations from question 1. Subtract them, and answer: Do these
combinations truly give the "Highest" and "Least" Voltage. If not, what
combination does?
