Standared reduction electrode potenitals...

Standared reduction electrode potenitals of three metals `A, B` and ` C ` are ` =0.5 V, - 3.0 V`, and ` -1.2 V` respectively. The reducing power of these metals are :

A

` B gt C gtA`

B

` A gtBgtC`

C

`C gt B gtA`

D

` A gtC gtb`

Text Solution

Verified by Experts

The correct Answer is:
A

More is reduction potntial , more is the power to get itself reduced or lesser is reducing power or greater is oxdising power.
