Standard electrode potential of three me...

Standard electrode potential of three metal `X, Y` and `Z` are `-1.2 V, +0.5 V` and `-3.0 V` respectively. The reducing power of these metals will be:

A

`Xgt Ygt Z`

B

`Ygt Zgt X`

C

`Ygt Xgt Z`

D

`Zgt Xgt Y`

Text Solution

Verified by Experts

The correct Answer is:
D
A reducing agent reduces the other and gets oxidized. Thus, the reducing power is inversely related to the value of reducation potential i.e., higher the reduction potential, lower the reducing power. Thus, the correct order is
`Z(-3.0 V)gt X(-1.2 V)gt Y(+0.5 V)`
