How would you determine the standard electrode potential of the system (Mg^(2+) )/ Mg ?

Explanation

We have to set up a half cell in which magnesium wire is dipped in 1 M magnesium sulphate solution. Couple this electrode which standard hydrogen electrode and measure the EMF of the cell so formed. Since the single electrode potential of SHE is zero, the measure EMF will be the standard single electrode potential of `Mg^2+(aq)/Mg` system. Since oxidation occurs at the magnesium electrode, its standard electrode potential will have negative sign
