The standard reduction potentials of three metals `A,B,` and `C` are `+0.5 V , -3.0V,` and `-1.2V`, respectively. The order of reducing power of these metals is

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.`
