A solution containing one mole per litre each of `Cu(NO_3)_2, AgNO_3, Hg_2(NO_3)_2` and `Mg (NO_3)_2` is being electrolysed by using inert electrodes. The values of standard electrode potentials in volt (reduction potentials) are,
`Ag|Ag^+ =0.80.2Hg|Hg_2^(2+) =0.79,Cu|Cu^(2+)=+0.34` and `Mg^(2+)=-2.37`
With increasign voltage, the sequence of deposition of metals on the cathode will be :
