    Select Question Language :


    A solution containing one mole per litre of each Cu(NO3)2, AgNO3, Hg2(NO3)2 and Mg(NO3)2, is electrolysed by using inert electrodes. The values of standard electrode potentials in volts are Ag/Ag+ = +0.80, 2Hg/Hg22+ = +0.79, Cu/Cu2+ = +0.34, Mg/Mg2+ = -2.37. With increasing voltage, the correct sequence of deposition of metals on the cathode will be

    Options :-

    1. Ag, Hg, Cu and Mg
    2. Mg, Cu, Hg and Ag
    3. Ag, Hg and Cu
    4. Cu, Hg and Ag
