  • question_answer
    Four alkali metals A, B, C and D are having respectively standard electrode potential as ?3.05,?1.66,?0.40 and 0.80. Which one will be the most reactive [MP PMT/PET 1988 ; CPMT 1983; MNR 1993; UPSEAT 2002]

    A)                 A            

    B)                 B

    C)                 C            

    D)                 D

    Correct Answer: A

    Solution :

                    More negative is the standard reduction potential, greater is the tendency to lose electrons and hence greater reactivity.
