Question
The reducing power of a metal depends on various factors. Suggest the factor which makes Li, the strongest reducing agent in aqueous solution.
Options
Sublimation enthalpy
Ionisation enthalpy
Hydration enthalpy
Electron-gain enthalpy
Solution
Hydration enthalpy
Explanation:
Li due to its small size it has a high value of hydration enthalpy. Due to the high hydration enthalpy of Li atom, it is the strongest reducing agent in the aqueous medium.
