  • question_answer
    The reducing power of a metal depends on various factors. Suggest the factor which makes \[Li\] metal the strongest reducing agent in aqueous solution:

    A) Sublimation enthalpy

    B) Ionisation enthalpy

    C) Hydration enthalpy

    D) Electron-gain enthalpy

    Correct Answer: C

    Solution :

    [c] Due to high hydration energy of \[L{{i}^{+}}\] cation the standard reduction potential of \[L{{i}^{+}}\] more negative among all alkali metal cation hence \[Li\] act as strong reducing agent water.
