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

Options

  1. ASublimation enthalpy
  2. BIonisation enthalpy
  3. CHydration enthalpy
  4. DElectron-gain enthalpy

Correct answer

C. Hydration enthalpy

Step-by-step solution

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