Question

Standard reduction electrode potentials of three metals A, B and C are +0.5 V, −3.0 V and −1.2 V respectively. The order of reducing powers of these metals is ____________.

विकल्प

• B > C > A

• A > B > C

• C > B > A

• A > C > B

Answer 1

Standard reduction electrode potentials of three metals A, B and C are +0.5 V, −3.0 V and −1.2 V respectively. The order of reducing powers of these metals is B > C > A.

Explanation:

The decreasing power is proportional to the reduction potential.
