Why sodium in liquid ammonia acts as reducing agents?

Hey mate ....
In ammoniacal solution, sodium metal eventually produces stoichiometric quantities sodium amide and dihydrogen gas. When the metal is introduced to the ammonia, a deep blue colour developes that is attributed to the solvated electron that eventually reduces the hydrogen of ammonia. Sometimes electrons couple to give a bronze colour. Preparative reactions in ammonia generally use a bit of iron salts to facilitate the electron transfer.
