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 enthylpy

C

Hydration enthalpy

D

Electron-gain enthalpy

Text Solution

Verified by Experts

The correct Answer is:
C
With small size of `Li^(+)` ion, lithium has the highest hydration enthalpy which accounts for its higgh negative `E^(@)` value and its high reducing power.
