The standard electrode potentials (E(M^(...

The standard electrode potentials `(E_(M^(+)//M)^(@))` 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

A,C,B,D

B

B,D,C,A

C

C,B,D,A

D

D,A,B,C

Text Solution

Verified by Experts

The correct Answer is:
C
As the value of reduction potential decreases the reducing power increases i.e.
`C lt B lt D lt A`
`(0.85), (0.6),(-0.76)(-1.2)`
