Question

Standard reduction electrode potentials of three metals A, B and C are respectively + 0.5 V, – 3.0 V. and – 1.2 V. The reducing powers of there metal is.

Options

• A >  B > C

• C > B > A

• A > C > B

• B > C > A

Answer 1

B > C > A

Explanation:

The greater the negative value of reduction potential, the greater the reducing power. As a result, B > C > A.
