JEE Main 2014 — Electrochemistry Question with Solution

JEE Main 2014 (09 Apr Online)

Question

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

Correct answer
CC > B > D > A

Step-by-step explanation

In complete cation electrolysis at cathode, the species having higher reduction potential is preferably reduced at cathode
E C ∘ > E B ∘ > E D ∘ > E A ∘
Hence,  C > B > D > A
will be the preference of deposition of these metals on competing.
