The reducing power of a metal depends on various factors. Suggest the factor which makes $$Li,$$ the strongest reducing agent in aqueous solution.
A.
Sublimation enthalpy
B.
Ionisation enthalpy
C.
Hydration enthalpy
D.
Electron - gain enthalpy
Answer :
Hydration enthalpy
Solution :
With the small size of $$L{i^ + }$$ ion, lithium has the highest hydration enthalpy which accounts for its high negative $${E^ \circ }$$ value and its high reducing power.
