The standard electrode potentials $(E_{M^{+} / M}^{o})$ of four metals $A, B, C$ and $D$ are $- 1 .2 V,$ $0 .6 V$ , $0 .85 V$ and $- 0 .76 V$ , respectively. The sequence of deposition of metals on applying potential is

Options:

Answer:

Solution:

In complete cation electrolysis at cathode, the species having higher reduction potential is preferably reduced at cathode
$E_{C}^{\circ} > E_{B}^{\circ} > E_{D}^{\circ} > E_{A}^{\circ}$
Hence, $C > B > D > A$
will be the preference of deposition of these metals on competing.
