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

`XgtYgtZ`

B

`YgtZgtX`

C

`YgtXgtZ`

D

`ZgtXgtY`

Text Solution

Verified by Experts

The correct Answer is:
d
Lower the `E^(@)` stronger is the reducing agent thus the reducing power decrease in the order
`Z(-30 V)gtX(-1.2 V)gtY(+0.54V)`
