Why does the solution of alkali metals in ammonia is conducting in nature?

Expert Answer
Alkali metals dissolve in liquid ammonia to give deep blue solutions that are conducting in nature. This happens because the alkali metal atom readily loses the valence electron in ammonia solution. Both the cation and the electron combine with ammonia to form ammoniated cation and ammoniated electron.
The ammoniated electron is responsible for the blue colour of the solution. The solution is made conduting in nature by both ammoniated cation and ammoniated electron.
On standing, the solution slowly liberates hydrogen as:
