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

`Y gt Z gt X`

B

`Y gt X gt Z`

C

`Z gt X gt Y`

D

`X gt Y gt Z `

Text Solution

Verified by Experts

The correct Answer is:
C
As the electrode potential drops , reducing power increases .
So , `Z (-3.0 V) gt X(-1.2 V) gt Y (+ 0.5 V)`
