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 these metals are:

• A. $\text{A}>\text{B}>\text{C}$
• B. $\text{C}>\text{B}>\text{A}$
• C. $\text{A}>\text{C}>\text{B}$
• D. $\text{B}>\text{C}>\text{A}$

Answer 1

Answer: (D)

More is the value of reduction potential, more is the power to get itself reduced or lesser is reducing power or greater is oxidizing power.
