An aqueous solution containing one mole per litre of each `Cu(NO_(3))_(2), AgNO_(3),Hg(NO_(3))_(2)` is being electrolysed using inert electrodes. The values of standard electrdoe potential in volts (reduction potential) are
`Ag^(+)|Ag=+0.80 2 Hg^(2+)|Hg=+0.79`
`Cu^(2+)|Cu=+0.34 Mg^(2+)|Mg=-2.37`
With increasing voltage, the sequence of deposition of metals on cathode will be
