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 2Hg|Hg^(2+)=+0.79`
`Cu|Cu^(2+)=+0.34 Mg|Mg^(2+)=-2.37`
With increasing voltage, the sequence of deposition of metals on cathode will be
