Hydration energy

Vedclass · Answer

(B) The reducing power of a metal in an aqueous solution depends on the electrode potential,which is determined by the sum of sublimation energy,ionization energy,and hydration energy. Although $Li$ has the highest ionization energy,it has the highest hydration energy due to its very small ionic size. The large magnitude of hydration energy compensates for the high ionization energy,making $Li$ the strongest reducing agent in aqueous solution.

List-$I$	List-$II$
$(a)$ $Li$	$(i)$ Absorbent for carbon dioxide
$(b)$ $Na$	$(ii)$ Electrochemical cells
$(c)$ $KOH$	$(iii)$ Coolant in fast breeder reactors
$(d)$ $Cs$	$(iv)$ Photoelectric cell

Which of the following is the most important factor in making lithium metal the strongest reducing agent?
