Question -
Answer -
The standard electrode potentialof Mg2+ | Mg can be measured with respect to thestandard hydrogen electrode, represented by Pt(s),H2(g) (1 atm) | H+(aq)(1M).
A cell, consisting of Mg | MgSO4 (aq 1M) as the anode and the standard hydrogen electrode as the cathode, is set up.
Then, the emf of the cell ismeasured and this measured emf is the standard electrode potential of themagnesium electrode.
Here,
for the standard hydrogenelectrode is zero.
