  • question_answer
    Standard reduction electrode potentials of three metals A, B and C are respectively + 0.5V, ? 3.0V and ? 1.2 V. The reducing powers of these metals are      [IIT 1998; AIEEE 2003]

    A)                 B > C > A             

    B)                 A > B > C

    C)                 C > B > A             

    D)                 A > C > B

    Correct Answer: A

    Solution :

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