Highly pure dilute solution of sodium in liquid ammonia:

Answer»

on EVAPORATION yield metals
exhibits electrical conductivity
produces sodium AMIDE and hydrogen GAS instantly
acts as POWERFUL reducing agent

Solution :`M+(x+y)NH_3 to [M (NH_3)_x]^(+) + [e (NH_3)_y]^(-)`.Blue colour of the solution is due to ammoniated electrons and good conductor of electricity because of both ammoniated cations and ammoniated electrons.
