EMF = 0.34 - (-0.76) = 1.10\ V

Anode (−)Zinc (Zn)

Cathode (+)Copper (Cu)

Cell EMF1.10 V

Electrode 24

Electrode 2 selectedCopper (Cu)

Select Zinc and Copper — confirm Zinc is the anode (negative electrode)
On the same Zinc-Copper pair, confirm the EMF reads about 1.10 V
Swap the order (Copper first, Zinc second) — confirm Zinc is STILL the anode, whichever slider it is on
Select Magnesium and Silver — the two ends of the series — confirm this gives the largest possible EMF (about 3.17 V)
Select Iron and Lead — two metals close together in the series — confirm the EMF is small, about 0.31 V
