Stadard reduction electrode potentials o...

Stadard reduction electrode potentials of three metals A,B and C are respectively `+0.5V, -3.0V` and `-1.2V`. The reducing powers of these metals are:

A

`BgtCgtA`

B

`AgtBgtC`

C

`CgtBgtA`

D

`AgtCgtB`.

Text Solution

Verified by Experts

The correct Answer is:
A
Higher the R.P. easier to reduce hence b etter O.A. thus species with higher reducing power (better R.A.) has a lower R.P. Therefore, correct order of reducing power is
`BgtCgtA`
