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 X gt Z`

B

`Z gt X gt Y`

C

`X gt Y gt Z`

D

` Y gt Z gt X`

Text Solution

Verified by Experts

The correct Answer is:
B
(b) `E_(X)^(@)=-12V`
`E_(Y)^(@)=+0.5V`
`E_(Z)^(@)=-3.0V`,
`:. Z gt X gt Y`[`:.`higher the reduction potential, lesser the reducing power. ]
