A solution containing 1 mol per litre of each Cu(NO3)2,AgNO3, and Hg2

1.	A solution containing 1 mol per litre of each Cu(NO3)2,AgNO3, and Hg2(NO3)2 is being electrolyzed by using inert electrodes. The values of standard electrode potentials in volts (reduction potential) are Ag\|Ag⨁=+0.80,2Hg\|Hg2+2=+0.79Cu\|Cu2+=+0.34,Mg\|Mg2+=−2.37with increasing voltage, the sequence of deposition of metals at the cathode will be (IIT-JEE, 1984)
Answer» A solution containing 1 mol per litre of each $C u (N O_{3})_{2}, A g N O_{3},$ and $H g_{2} (N O_{3})_{2}$ is being electrolyzed by using inert electrodes. The values of standard electrode potentials in volts (reduction potential) are $A g \| A g^{⨁} = + 0.80, 2 H g \| H g_{2}^{2 +} = + 0.79$ $C u \| C u^{2 +} = + 0.34, M g \| M g^{2 +} = - 2.37$ with increasing voltage, the sequence of deposition of metals at the cathode will be (IIT-JEE, 1984)
