Question

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`

Answer 1

Correct Answer - A
`{:(" "A", "B ", "C),(E_(cell)^(@)", "+0.5V","-3.0V","-1.2V):}`
The reducing power follows the followig order `BgtCgtA`
