NEET Chemistry The s-Block Elements Questions Solved

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

(a) Sublimation enthalpy            (b) Ionisation enthalpy

(c) Hydration enthalpy               (d) Electron-gain enthalpy

(c) Due to high hydration energy of Li+ cation, the standard reduction potential of Li+ is more negative among all alkali metal cations hence Li acts as strong reducing agent in water.
