A solution of sodium metal in liquid ammonia is strongly reducing due to the presence of
A.
sodium atoms
B.
sodium hydride
C.
sodium amide
D.
solvated electrons
Answer :
solvated electrons
Solution :
The free ammoniated electrons make the solution of $$Na$$ in liquid $$N{H_3}$$ a very powerful reducing agent.
NOTE : The ammonical solution of an alkali metal is rather favoured as a reducing agent than its aqueous solution because in aqueous solution the alkali metal being highly electropositive evolves hydrogen from water (thus $${H_2}O$$ acts as an oxidisng agent) while its solution in ammonia is quite stable, provided no catalyst (transition metal) is present.
