3.1 How would you determine the standard electrode potential of the system ?
To determine the standard electrode potential of the given system we need to use a hydrogen electrode. In the setup, we shall put a hydrogen electrode as cathode and Mg | MgSO4 as an anode.
Now we will measure the emf of the cell. This emf will be the standard electrode potential of the magnesium electrode.
E°cell = E° right – E°left
E°left =0 ( The standard hydrogen electrode is always zero)
Hence
