A solution containing one mole per litre of each `Cu(NO_(3))_(2), AgNO_(3), Hg_(2)(NO_(3))_(2)` is being electrolysed by using inert electrodes. The values of standard electrode potentials in volts (reduction potentials) are  `Ag^(+)//Ag = +0.80 V, HG_(2)^(2+)//Hg = +0.79 V`  `Cu^(+)//Cu = +0.34 V, Mg^(2+)//Mg = -2.37 V` With increasing valtage, the sequence of deposition of metals on the cathode will b
