Standard electrode potential of three me...

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

A

`BgtCgtA`

B

`AgtBgtC`

C

`CgtBgtA`

D

`AgtCgtB`

Text Solution

Verified by Experts

The correct Answer is:
a
Higher the `E^(c-)._(o x i d ation)` or lower the `E^(c-)._(reduction)`, better is the reducing agent. So, `BgtCgtA.`
