A solution containing one mole per litre of each Cu(NO3)2; AgNO3; Hg2(NO3)2; is being electrolysed by using inert
electrodes. The values of standard electrode potentials in volts (reduction potentials) are : (1984 - 1 Mark)
With increasing voltage, the sequence of deposition of metalson the cathode will be :
  • a)
    Ag, Hg, Cu, Mg
  • b)
    Mg, Cu, Hg, Ag
  • c)
    Ag, Hg, Cu
  • d)
    Cu, Hg, Ag
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
A solution containing one mole per litre of each Cu(NO3)2; AgNO3; Hg2(...
The reduction potentials (as given) of the ions are in the order :
Mg2+ (aq.) will not be reduced as its reduction potential is much lower than that of water (–0.83 V). Hence the sequence of deposition of the metals will be Ag, Hg, Cu.
