Dilute solutions of alkali metals in liquid NH_(3) are blue. It is the ammoniated electron which is responsible for the blue colour of the solution, and the electrical conductivity is due to the ammoniated cation, [M(NH_(3))_(x)]^(+) as well as the ammoniated electrons, [e(NH_(3))_(y)]^(-) , values of x and y depend on the extent of solvation (by NH_(3) ). Dilute solutions are paramagnetic due to free electrons. What happens if alkali metals is allowed to react with concentrated liquid ammonia?
