The standard electrode potentials 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 :
A, C, B, D
B, D, C, A
C, B, D, A
D, A, B, C
The higher the standard electrode potential of the metal, greater is its tendency to get reduced and get deposited on the electrode.
Order of the given
The order of deposition will be C, B, D, A.
Hence, the correct answer is Option (3)
