What does the Magnitude of Standard
Electrode potential, E0 imply?

E0F2/F- = + 2.87 V
E0Ag+/Ag = + 0.799 V
E0H2/H+ = 0.000 V
E0Cd2+/Cd = - 0.403 V
E0Li+/Li = - 3.04 V

The more positive E0red the stronger the oxidizing agent
The more negative E0red the stronger the reducing agent

What does the sign of the Cell
Potential imly?? -IUPAC sign convention

Consider the following cell:

CuCu2+ (0.02 M)  Ag+ (0.02 M)  Ag

According to the schematic presentation:
Ecell = EAg ─ ECu
The measured E of this cell, Ecell = +0.41 V----- positive
This indicates that the cell in such schematic presentation works
as GALVANIC Cell.

Consider the following cell:

Ag  Ag+ (0.02 M)  Cu2+ (0.02 M)  Cu

According to the schematic presentation:
Ecell = ECu ─ EAg
