question_answer 40)

  The reducing power of a metal depends on various factors. Suggest the factor which makes lithium, the strongest reducing agent in aqueous solution : (a) sublimation enthalpy                                               (b) ionisation enthalpy (c) hydration enthalpy                                                   (d) electron gain enthalpy

Answer:

  (c) Li is the strongest reducing agent due to high hydration enthalpy of Li-ion as it has very small size.
