Alkali metal dissolve in liquid ammonia to form deep blue solution which has free electrons or ammoniated electrons. 

\mathrm{M}+(\mathrm{x}+\mathrm{y}) \mathrm{NH}_3 \rightarrow\left[\mathrm{M}\left(\mathrm{NH}_3\right) _\mathrm{x}\right]^{+}+\left[\mathrm{e}\left(\mathrm{NH}_3\right) _\mathrm{y}\right]^{-}

The free ammoniated electrons make the solution of \mathrm{Na} in liquid \mathrm{NH}_3 a very powerful reducing agent.
